We analyzed 12 million outreach emails to answer the question:

What’s working in the world of email outreach right now?

We looked at subject lines. We looked at personalization. We even looked at follow-up sequences.

Along with our data partner for this study, Pitchbox, we uncovered a number of interesting findings.

Here is a Summary of Our Key Findings:

1. The vast majority of outreach messages are ignored. Only 8.5% of outreach emails receive a response.

2. Outreach emails with long subject lines have a 24.6% higher average response rate compared to those with short subject lines.

3. Follow-ups appear to significantly improve response rates. Emailing the same contact multiple times leads to 2x more responses.

4. Reaching out to multiple contacts can also lead to more success. The response rate of messages sent to several contacts is 93% higher than messages sent to a single person.

5. Personalized subject lines boost response rate by 30.5%. Therefore, personalizing subject lines appears to have a large impact on outreach campaign results.

6. Personalizing outreach email body content also seems to be an effective way to increase response rates. Emails with personalized message bodies have a 32.7% better response rate than those that don’t personalize their messages.

7. Wednesday is the “best” day to send outreach emails. Saturday is the worst. However, we didn’t find an especially large difference in response rates between different days that messages were sent.

8. Linking to social profiles in email signatures may result in better response rates. Twitter was correlated with an 8.2% increase, LinkedIn an 11.5% increase, and Instagram a 23.4% increase.

9. The most successful outreach campaigns reach out to multiple contacts multiple times. Email sequences with multiple attempts and multiple contacts boost response rates by 160%.

10. Certain types of outreach get higher response rates than others. Outreach messages related to guest posting, roundups and links have an especially high response rate.

We have details and additional data from our study below.

Most Outreach Emails Are Ignored or Deleted

You may have heard that it’s challenging to get people to reply to cold outreach emails. According to our data, poor response rates do appear to be the norm.

In fact, we found that only 8.5% of all outreach emails receive a response.

Only 8.5% of all outreach emails receive a response

This response rate is similar to what several cases studies, like this one from the Moz blog, have previously found.

The fact that 91.5% of cold outreach messages are ignored may not come as a surprise. After all, generic outreach emails like this are extremely common:

Generic outreach email

Fortunately, our research found several factors that helped certain outreach emails outperform the average. We will cover these findings later in this post.

But for now, it’s important to note that very few outreach emails receive a response.

Key Takeaway: 91.5% of outreach emails are ignored.

The Ideal Outreach Email Subject Line Length Is 36-50 Characters

Our study found that long subject lines get a significantly higher response rate than shorter subject lines.

Specifically, subject lines between 36-50 characters get the best response rate.

The ideal length for subject lines is 36-50 characters

To compare subject line response rates, we placed them into 5 buckets: short, medium, long, very long and extremely long.

And we found that long subject lines outperformed short subject lines by 32.7%.

Long subject lines get higher response rates than short subject lines

Why do long subject lines do best?

It’s likely because longer subject lines give you an opportunity to fully describe the content of your message.

For example, imagine a super short subject line like: “Quick Question”.

Subject line too short

At 13 characters, it’s impossible for your recipient to know what your email is about. It could be a question about their sales process. Or their lunch plans.

Plus, because it doesn’t note anything specific, it makes your outreach email seem generic before they’ve even opened it.

Contrast that with a subject line like: “Quick Question About Your Latest Blog Post”

Ideal subject line length

This subject line is much more specific. That way, if the recipient decides to open your email, they know what to expect.

However, it’s possible for your subject line to be too long.

For example, “Quick Question About Your Latest Blog Post About The Top 10 Paleo Diet Myths” is an extremely descriptive subject line. But it’s likely to get cut off by most inboxes (like Gmail):

Subject line too long

Key Takeaway: Long subject lines get 32.7% more responses than short subject lines.

Sending Follow-up Messages Significantly Improves Response Rates

Should you send follow-up messages to people that don’t reply to your initial outreach?

According to our findings, yes. We found that multiple outreach messages work better than a single message:

Multiple outreach messages result in higher response rates

While sending 3 or more messages results in the best overall response rate, sending just one additional follow-up can boost replies by 65.8%.

A single follow-up message can boost replies by 65.8%

Why do follow-ups work so well?

Simply put: people receive lots of emails in their inbox every day. In fact, The Radicati Group found that the average office worker receives 121 emails per day.

With 100+ emails to sift through per day, the chances of your single outreach email getting seen, opened and replied to is pretty slim.

But when you send more than one message, you have yet another chance to stand out and push through the noise in someone’s inbox.

Of course, there’s a right and wrong way to send follow-up messages.

Annoying follow-ups like these can damage relationships, lead to spam complaints, and overall, do more harm than good.

Annoying follow-up email

However, gentle follow-ups that provide additional context can improve conversions without burning bridges.

Gentle follow-up

Key Takeaway: Follow-ups can significantly improve outreach conversion rates. In fact, a single additional follow-up message can lead to 65.8% more replies.

Reaching Out to Several Contacts Increases the Odds of a Response

We looked at the effect that reaching out to several contacts at the same organization had on outreach conversions.

And we found that, compared to a single contact, sending emails to more than one contact improves response rates by 93%.

Reaching out to several contacts increases response rate

We also looked at how outreach success rate correlated with number of contacts. We found a clear pattern that more contacts leads to more responses.

Outreach reply rate is proportional to number of contacts

However, we did find a point of diminishing returns at 5+ contacts.

If you’re reaching out to a single-author blog, you probably don’t need to worry about sending messages to several different contacts.

However, multiple contacts becomes important when reaching out to large websites with dozens of employees. That’s because it can be hard to tell who exactly is responsible for which task (even with the help of an org chart and “About Us” page).

For example, let’s say that you’re sending an outreach message to a large publisher as part of a link building campaign. Should you email the author of the article? Or the editor of the blog? Or maybe the best person is the head of content.

It’s almost impossible to know without an intimate understanding of the organization’s inner workings. That’s why it usually makes sense to reach out to a single person. Then, if you don’t hear back, try again with another contact. That way, over time, your message should get in front of the person that is most likely to add your link to the post.

Key Takeaway: Having multiple contacts to reach out to increases your chances of getting through. In fact, outreach emails sent to multiple contacts can boost response rates by 93%.

Personalized Subject Lines Lead to More Replies

Personalizing emails is considered an outreach best practice. However, to our knowledge, there hasn’t been any research done to support this strategy.

That’s why we decided to investigate the effect of personalization on outreach email replies. Specifically, we compared the response rates between messages that did and didn’t use personalized subject lines.

Our data showed that personalized subject lines got nearly 1/3rd more replies than those without personalization.

Personalizing subject lines lead to more replies

Why do personalized subject lines lead to more responses?

Although it’s difficult to fully answer this question from our data alone, my theory is that personalized subject lines help you stand out in someone’s crowded inbox.

For example, take a non-personalized subject line like: “More Leads”. For someone that’s hurriedly scanning incoming emails from their iPhone, “More Leads” doesn’t compel them to see or open the message.

Non-personalized subject line

On the other hand, adding a bit of personalization makes your subject line much more compelling to the person on the receiving end of your message.

Personalized subject line

Key Takeaway: Emails with personalized subject lines boost response rate by 30.5%.

Personalizing Email Body Copy Can Significantly Improve Response Rates

As we just outlined, personalized subject lines are correlated with higher response rates (likely due to a higher email open rate).

However, we wanted to see if the benefits of personalization extended to the outreach email body itself.

Our data showed that personalizing the body of outreach emails also improved conversion rates. Specifically, personalized messages received 32.7% more replies than those that weren’t personalized.

Personalizing email body copy can significantly improve response rates

Generic outreach messages are easy to spot. For example, here’s one that I received a few days ago:

Generic outreach email – Guest posting

The telltale “Hi,” or “Hello,” is usually enough to let you know that this exact same email has been sent to hundreds of other people.

On the other hand, even a relatively small gesture, like using the person’s first name, can go a long way.

And for those that are interested in getting the highest reply rate possible, writing outreach emails from scratch (or working from a template with lots of room for personalization), seems to work best. Here’s an example of one such outreach email someone recently sent me:

Personalized follow-up email

According to our research, personalizing subject lines and body copy is correlated with above-average response rates. Yes, personalizing takes more time and effort. But the data suggests that this extra work pays off.

Key Takeaway: Emails with personalized bodies boost response rate by 32.7%.

Wednesday Is the Best Day To Send Outreach Messages

Several industry studies have set out to answer the “best day to send emails” question. However, most of these studies (like this one from GetResponse) are specific to newsletter messages. They also tend to focus on open rates, not reply rates.

Which is why we decided to look at how response rates differed based on the day of the week that messages were sent out.

Our data showed that Wednesday had a slight edge over the other 6 days of the week. Also, Saturday appears to have the worst response rate.

Best day of week to send outreach emails

However, I should note that the differences in response rates were somewhat small.

For example, when we looked at the response rate for the “best” day (Wednesday) to the “worst” day (Saturday), we found that messages sent on Wednesday had a 1.99% higher overall response rate.

Comparing outreach response rates Saturday .vs. Wednesday

In other words, according to this data, sending outreach emails on Wednesday vs. Saturday could theoretically boost your response rate from 6% to 7.99%. If you’re only sending a few dozen outreach messages per month, this may only lead to an additional reply or two.

However, this finding is more significant if you’re doing outreach at scale. That’s because, while 1.99% may not mean much in absolute terms, it amounts to a 33.1% higher relative response rate. Which is significant for those that send out a large amount of outreach emails every month.

We also compared response rates for messages sent during the week vs. those sent on the weekend.

And we found that outreach emails sent Monday through Friday had a 23.3% better conversion rate than emails sent on Saturday or Sunday.

Outreach emails sent on weekdays get significantly more replies than those sent on weekends

Key Takeaway: Outreach emails sent on Wednesday get more responses than any other day of the week. However, most small-scale outreach campaigns don’t need to organize their sequences based on the day of the week.

Linking to Social Profiles May Slightly Improve Outreach Response Rates

Do social profile links in the email signature affect response rates?

According to our study, they do. Messages that contained links to social profile links in the sender’s signature had an 9.8% higher average response rate compared to messages without them.

Linking to social profiles may slightly improve outreach response rates

We also broke down the impact of social signature links by social network. We found that linking to Twitter, LinkedIn and Instagram profiles positively affect response rates. However, linking to Facebook profiles didn’t seem to make a dent.

Links to Instagram, LinkedIn and Twitter may lead to more outreach replies

Why would social profile links lead to more responses?

I have two theories:

First, links to social profiles make you seem like a living, breathing person.

Brian email signature

I doubt that many recipients actually click on these social signature links. However, their mere presence may suggest: “I’m not an outreach robot. I’m a person that’s reaching out to you”.

Second, it’s possible that social profile links may not have any direct impact on responses at all. It could be a case of correlation, not causation.

For example, people that tend to be transparent may also spend more time personalizing their messages, which is the true underlying cause of the improved response rates.

While it’s impossible to glean the exact effect of social profile links on outreach response rates, they don’t appear to hurt conversions. Which makes them something worth testing.

Key Takeaway: Outreach emails that contain links to social profiles have a 9.8% higher response rate than those without social profile links. Links to Instagram and LinkedIn appear to be most effective.

Email Sequences That Involve Multiple Contacts and Multiple Messages Perform Best Overall

As I covered earlier in this write-up, follow-up messages and sending multiple contacts are correlated with higher outreach reply rates.

We also decided to investigate the combined effect that these two strategies had on conversion rates. Specifically, we compared reply rates between a single email to a single contact with a 3-part email campaign to several different contacts.

Our data showed that more contacts combined with sequencing yield a 160% higher response rate than sending a single message to a single contact.

Email sequences that involve multiple contacts and multiple messages perform best overall

Key Takeaway: Taken as a whole, campaigns that involve sequences that go out to several contacts perform significantly better than one-off emails to a single person.

Outreach Emails About “Links”, “Guest Posting” and “Roundups” Have Especially High Response Rates

We investigated reply rates between eight common email outreach topics.

Specifically, we looked at the reply rate for outreach emails related to:

  • Link building
  • Guest posting
  • Sponsorships
  • Infographics
  • Resources
  • Reviews
  • Mentions
  • Roundups

And we found that outreach emails about guest posting, roundups and link building all had an above-average response rate.

Outreach email response rate by topic

This is an especially interesting finding considering that many content marketing and SEO experts consider guest posting and roundups “dead”.

Guest-posting collage

However, at least according to our study, site owners are still largely receptive to pitches for guest posts and expert roundup invitations.

Emails related to sponsorships also tended to get a fair share of replies. I found this noteworthy as Influencer Marketing, which relies heavily on paid product placement and promotion, is growing. It appears that influencers are still happy to receive pitches from brands that want to sponsor their website, YouTube channel or Instagram profile.

Our data also showed that messages about infographics receive relatively few replies.

This may be due to the fact that infographics have lost the novelty they once had. Or that the most infographic-focused outreach is untargeted.

For example, I got this infographic pitch in my inbox a few months ago:

Infographics pitch

My site has never written about or even touched on holiday promotions. This was clearly someone that created a mediocre infographic with the hope that mass outreach would help get the word out.

Key Takeaway: Emails about guest posts, roundups, links and sponsorships tend to get the best response rates.


I’d like to thank Michael Geneles from Pitchbox for providing the data that made this study possible. I also want to give a shout out to Alex Gopshtein for digging deep into the data and making it easy to understand and digest.

And for those that are interested, here’s a link to our study methods.

Now I’d like to hear from you:

What’s your #1 takeaway from today’s study?

Let me know by leaving a comment below right now.

    1. Thanks Niyi. I 100% agree. It just makes sense that a signature would help you seem like a real person vs. an automated spam machine.

      1. Social links in the signature might help you build your credibility but , if it’s mass outreach the it doesn’t work, as of my testing spam filters can easily detect your mass signatures and email may end up in spam!

        1. I don’t think that’s true. It’s perfectly normal to have the same signature (Especially if you personalize the actual message).

  1. Thanks for this. Tell me though the results of your own email blast about this post. Which of these guidelines here did you observe, and what was the result? Note that I got your email on a Tuesday. Maybe you should have waited a day? 😉

  2. My biggest takeaway is that it may be most effective to focus on more personal 1:1 outreach emails rather than trying to use a mailmerge. A 50% response on 20 personal emails vs a 10% response on 100 emails would still net you the same amount (10) of responses, and the first group would probably actually talk to you again in the future. Seems like 1:1 might be the best long term solution.

    1. Hey David, great comment. And I 100% agree: you usually get the same amount (or more) replies from personalized emails than you do with a blast. Plus, you’re not burning bridges, getting lots of spam complaints, etc. Personalized is the way to go.

    1. Hi Richard, thank you. Yup, that was interesting. There seems to be a “sweet spot” when it comes to subject line length.

  3. Incredible post Brian!

    Outreach is what I do all day everyday and this has to be one of the most useful posts you’ve ever written 🙂

  4. As I receive your email Brian, I see that you do not use any templates. You keep them as simple as possible. I use a simple mailchimp template. I will read more on this article and see what can be even better after all your findings. Again, thanks for another awesome post!

  5. Very Informative, learnt lot of new information from the post. Great analysis. Tons of thanks for coming up with such awesome article.
    Have a great day!

  6. Great share, I am also running the infographic outreach email campaigns, but not getting much results.

    But with your listed ideas and results, I will definitely going to update my campaigns

    1. Sounds good. I’ve been getting a lot of horrible infographic pitches lately. So I think people are tuning out anything infographic-related right now unless the pitch is amazing (and our data backs this up).

  7. Hi Brian,
    Great post as always. Quiet surprised that long subject lines get better responses. Did you investigate the use of emoji in the text or subject of emails? I believe these do add to the friendliness of emails and possibly to reponse/open rates?

    1. Hi Michael, thank you. We didn’t look at emojis. That would be super interesting to look at in a future version of this study for sure.

    1. Thanks François. That’s likely the case. We didn’t look into niches and industries. But it would make sense that B2B would have higher open and response rates during the week than B2C.

  8. Fantastic resource Brian. I’m just about to start a somewhat large email marketing campaign so this is very timely info! Interesting to see that email marketing is not totally dead (as many say), however, I would say that mass-produced, scatter-gun email marketing is.

    1. Hey Ian, thank you. As someone that does email marketing (outreach and newsletter-based) all the time, I can confirm that email is NOT dead. Far from it.

    1. Thanks Akhil. I was fortunate enough to have an amazing data partner (PitchBox) that helped provide the data. This made the process a lot easier.

  9. Very interesting insight, our outreach emails only have an open rate of 2%. We will be changing them now especially length of title!

    Cheers Brian another great experiment

    1. Hey Matt, Sounds good. A 2% open rate is pretty low. I’d look at your deliverability rates too. That could be part of the issue.

  10. I was about to shut my mac and your email just pop up brain and I instantly hook with this yet another resourceful study. I always thought it’s all about quantity when it comes to outreach and never intended to personalized my message. This Study would surely help me.


    1. Hey Dan, there’s an element of quantity in that you need to reach out to enough people to make a campaign work. But it’s more important than ever to personalize every email that you send out.

  11. Brian, this is some really eye-opening stuff. As outreach is such a staple in my everyday job, this helps shine some light into what works, what doesn’t seem to work, and things to change for the future!

    Thanks again!

      1. Your research seems to be right in line with much of my personal experience. In a much smaller sample (500<), heavily targeted, and personalized approach, I've seen open rates of 35% and click/interaction rates of around 25%. Avoiding burning those bridges and finding relevant sites seems to help the overall campaign. Additionally, outreaching to multiple contacts is HUGE!


  12. Amazing! Already shared it to my colleagues. Thanks, as always, Brian for your brilliant posts and doing all the hard work for most of the digital marketing community. Also, thanks to the Pitchbox team! You guys are awesome!

  13. This is really good with some amazing insights.

    Just wanted to ask you for a long time now, which tool you use to create such amazing graphics/images?

  14. Brian….THANK YOU. This is great info. I appreciate the work that went into this. I need to read it more slowly and implement it into my email campaigns. Seriously good stuff. This takes a lot of the confusion out of what to do and not to do. THANK YOU
    Have a gentle day.

    I follow your videos on UT. Thank you for all you do.

    1. Hi Betsy, you’re welcome. Trust me, I’ve been there. When I first got started with email outreach I had no clue what I was doing. I sure wish I had industry studies like this to help me back then!

  15. Less than 30 mins and I’m already comment no >46!

    Great post Brian, loved the examples of great follow up messages. Should have totally read this post before sending you my follow up email *face palm*.

    Great read!

    1. Hi Lily, that’s what happens when you send a newsletter to 130k subscribers, LOL. No worries. I actually saw your followup, which was good. I’m just not doing any roundups right now.

  16. Hi Brian,

    Email outreach is still one the effective and best way to get quality links as well as building relationship with like minded person.

    You have elaborated very well each steps to email outreach. I’m gonna try them.

  17. Great post Brian.

    The ‘Hey, I saw your post about ” and thought it was an amazing piece of content!’ has got to be the most cliched outreach email ever! I manage the inbox for several crypto publications and I swear 50%+ of outreach emails have a fake compliment like that.

  18. This was very informative, as always. It would be interesting to see a follow-up post from you comparing the various email outreach providers, including Pitchbox.


    1. Hey Ian, thanks. That would be interesting. Do you think there’s a big difference in terms of clients that use different outreach tools?

      1. I am not sure, and my perspective might be skewed based on the number of reviews I have seen, the bulk of which tend to focus on outreach for guest posting as a way to building links.

        I’ve been spinning wheels over the last several days trying to decide which tool has the best overall features that includes lead prospecting to grow my business.

        I figured if I am going through this decision analysis there may be others going through the same exercise and who better to provide an unbiased overview than Brian Dean.

  19. Thanks Brian for this article! I appreciate you taking the time to do this study and sharing your results with the rest of us who are still trying to figure out what works in outreach. You’ve talked a lot about response rate as a success metric, but I wonder about the overall conversion rate when it comes to people saying “yes” to whatever you’re proposing. Let’s say you’ve hit a 50% reply rate to your link building emails. How many of those actually include your link in their content? What does it depend on? It might be an entirely different post I suppose 😉 I’m asking because as a person who gets tons of those emails every day, I actually respond to those personalized ones (where I see someone clearly made an effort) but most of the times the response is “no”.

    1. Hi Marta, you’re welcome. That’s true: reply rate isn’t a perfect way to see what’s working. After all, I’ve received a lot of replies from people that are a lot worse than “no”!

      However, we didn’t have “conversion” available as a metric. Plus, in my experience, replies at least mean you’re doing something right. The truly horrible outreach messages are completely ignored. Hope that makes sense.

      1. It does! I also think that a reply (apart from those worse than “no”) usually opens doors to more conversations, whether it’s a partnership, learnings exchange, or more.
        From your experience, though, how many of those who reply, convert (if it’s a link request for example) ? 🙂

  20. Specifically, I’m going to focus more on the subject line.


    I have a small question
    What if we include the name of the person in the starting of the outreach email body?
    Will it help to get the user attention?
    Or else just start with simple (Hi)

    What’re Brian thoughts in this?

  21. Hi Brian – by far, your content is my favorite on so many subjects; the seo practical advice, the copywriting tips, the YouTube tips— all of it.

    You do the hard work and I wanted you to know that I am forever grateful and in general awe.

    But this outreach subject – uuugh. As a publisher I am inundated with these emails. They are all asking me to invest valuable time on poor content with very little return.

    I would advocate outreach emails being sent ONLY AFTER you’ve built a relationship with the publisher. For example; comment on their articles, share their articles, engage on social.

    Knowing who you are and that you’ve already done something for them will trip the reciprocity trigger – and if your content is good. BOOM. They will comply.


    1. Hi Ivana, thank you. I really appreciate it.

      You raise a great point. As a fellow publisher, I know exactly the emails you’re referring to. They’re annoying. And as our data shows, they don’t work.

      Even though we didn’t look at relationship building here, you’re right: it’s a smart move and something that can increase the odds of success by 10-20x.

  22. These are great and helpful findings, but how to you reconcile the idea of personalized message with better response in multiple recipients?

    1. Good question, Craig. I don’t recommend reaching out to multiple contacts at the same time. We looked at sending a sequence of messages to someone else at the organization after the first person doesn’t reply. Does that make sense?

      1. Glad you clarified this. I had the same question and was hunting thru the comments hoping to find an answer. Much thanks.

  23. I think my #1 takeaway would have to be creating follow up messages with additional context.
    Also, the example follow up email included really great actionable advice for persons wanting to grow an email list from scratch.
    Really great article, as always 🙂

  24. I have been doing trying it the wrong way. Let me see how it goes following your procedures.

    I’d love to learn how to improve my blog too.

    Thanks Brian
    Waiting for answers

  25. Maybe I missed this in the study but I didn’t see an analysis on the size of the content. Do longer or shorter emails work?

    1. Hi Gabby, we didn’t look at email length. That would be something cool to check out in a future study for sure.

  26. Hey Brian,

    I noticed you did not use socials in your email, no personalization, and your subject is 13 characters, I am guessing this is due to you having a different purpose? Curious, if you have any examples of the best way to display social networks. Icons vs the full words?

    1. Hey Richard, I think you’re talking about today’s newsletter email? That’s really different than email outreach. In terms of icons, you can use something like

  27. Personalized messages having a higher response rate makes sense to me. At the end of the day, it’s a human reading the e-mail. Plus, if it’s too much of a canned message it most likely will be detected as spam.

    I love all the data you presented Brian, keep up the great work!! Your advice has been a big help in growing my money and bills blog. Cheers! Scotty B.

    1. Thanks Scott. Great point: with all the numbers being thrown around it’s easy to forget that there’s an actual person on the other end of your message.

  28. This is a great research Brian, I definitely needed something like this to read about the email outreach.

    I still haven’t figured out how to make it work the email outreach process and I hope this helps me in that regard.

    Thank you, you are awesome:)

  29. Hi Brian,

    Great post. I’m curious. Did you measure the positive vs. negative responses per category? Did the greater response always parallel the positive response? And by positive response, I mean… “Thanks for sending. We’re going to share your article on our blog.” vs. “Get lost kid.”


    1. Hey Shad, we didn’t look at that actually. Just overall responses. I’m sure some responses were of the “get lost kid” variety. But in general, a response is usually a good sign with outreach.

  30. Love your articles Brian! Really help keep us on the ball with SEO related topics.
    Would you ever consider doing an article like this about Email Marketing Open-Rates & Responses?

      1. I think he was saying that he got the email address from a website/company where didn’t show the exact name of this email address. How to personalize the email body? how to say Hi xxxx?

  31. We regularly run reach out email campaigns targeting the US real estate market. The personalization tactic is one solid way to increase open rates and get responses. Even in India, when we send to lists that contain many Gmail users, personalization allows us to avoid the promotions tab and land emails in the main inboxes.

  32. Brian,
    thank you for this in depth study.
    Its good to see that guest posting still works well.
    Also the best day for sending emails is a Wednesday.
    Information like this helps no end in targeting with email campaigns!

    1. Hi Ged, you’re welcome. Yup, it seems that publishers are still open to guest post pitches (especially compared to infographics).

  33. Be honest, be upfront about your offer and know that I know my value to you and offer something useful to me in return. Hint $5 or $50 or exposure to your 200,000 followers not interested in my content does not cut it. I am bombarded with outreach emails daily and rarely respond. Most are deleted instantly because they clearly come from a fake person and demonstrate no knowledge of me or my business. To me demonstrating authenticity and value is basic business and human etiquette. People who approach publishers thus way will be incredibly successful

    1. Hey Katy, that’s a great point that’s lost on a lot of people that do outreach: be up front. I’m surprised at how many outreach emails I get where I have no clue what the person actually wants me to do.

  34. Sweeet!
    I’ve been looking for a study like this for a while now and who else could make it more awesome than Brian Dean. I’ve been following you since the “200 ranking factors” and your emails are my favorite that land in my inbox, no need for special subjects to catch my attention, 100% open rate 🙂
    Anyhow, thanks for another great study, I’ve been sending some banner advertising promotions lately and tips from here will surely be put into practice in the following ones.

    1. Hey Jure, awesome! That’s from back in the day for sure. I published that post 6+ years ago. Time flies! Anyway, great to have you as a subscriber and I’m glad you enjoyed today’s post.

      1. Maybe just one thing I forgot to add in the original comment. That “multiple contacts” option seems a bit hard for us now in Europe since the introduction of GDPR, as we can only target non-personal emails like info, sales or, not directly to name@.. without consent. And of course, this affects the personalization part as well, as unless clearly stated on the website, you’ll never know where that info mail is gonna end up.
        “Lucky us”.

  35. Thanks for the great info! It makes sense that expanding your pool of contacts would increase the likelihood you get a response. And personalization has long been an important factor, so I wasn’t surprised to see that it was effective. Although I’ve been using personalization in my email content for a while, I hadn’t thought about putting it in my headlines, so that’s definitely something to consider.

    1. Hi Alison, you’re welcome. Personalizing subject lines (with their name, website or something else unique to them) is totally worth testing. It really helps those messages stand out in a crowded inbox!

  36. Hey Brian! I’m your regular blog reader. This post is also awesome as the other ones. You just did a great job. I just inspired from you and thinking to work as you do, awesome. Your work is really great. You just did very few people ever do. If possible, can I reach to you? If yes, how?

  37. Hey Brian,
    This is awesome guide, you are the king of content writing.
    Just Waiting your YouTube video please let me know when you will make it.


  38. Thank you so much for these ingenious insights!

    I’m not the outreach type of person, but with this, I’ve gotten lots of pointers towards the right direction.

    Thank you Brian!

  39. Hi Brian Dean, i got your mail…. i read the post, But i think its a very taking time process to find your targeted users. Also some times outreach work only 2% out of 100

  40. I’m going to set an auto response to send this article to all the crappy outreach emails I get – maybe they can stop bothering me with stupid copy & paste spam 🤣🤣

  41. I can definitely speak to the personalized subject lines.

    I’ve had to do a double take a few times and sometimes click when intuitively I knew that I had no contact with this person before.

    Anyways, thanks for the great post!

    1. Hey Arash, same here. I think it’s partially due to the fact that a personalized email shows that the person put in some effort. But like you said, it’s mostyle due to the simple fact that a personalized subject line simply stands out.

  42. Hi Brian,

    I haven’t started using email outreach just yet, but when I do (very soon), I’ll be coming back here to re-read your post! Great work, once again.

    Thanks a lot

  43. Few interesting facts I came across specifically the long subject line. Obviously, a title like “Quick question” never worked but the character count you mentioned is something different. As usual another amazing work, Brain.

  44. Fantastic article backed with data from a great tool. Thank you for sharing Brian.

    Fyi, your email with the short title brought me here lol

    1. Thanks Simon. A lot of people have pointed that out, LOL. But this was a newsletter email which is different than an outreach email.

  45. Thanks for the awesome content! Just wondering when we (business owner) use social profile as signature, should we use a personal or company social profile? What’s your thoughts on this ?

  46. As a new creator of an affiliate website, I am not at the stage of outreach yet. However it crossed my mind in the past, what seems like a confusing set of tasks for outreach is now, thanks to your great post here, a systematic approach to link building in the foreseeable future.

    Thanx, as always Brian, for the superlative resource of information you amazingly produce. I don’t know how you do it given the seemingly large magnitude of work involved. Great Job!

  47. Love this research 🙂 I’m an avid user of Pitchbox and was hoping Backlinko and Pitchbox would marry on a study. While I’ve used most of these strategies, I haven’t tried the social media link in the signature (definitely something I’ll try out). However, from the campaigns I’ve run for guest posting, using a subject line similar to “RE: (recent blog post title)” seems to work really well.

    I theorize this is more successful because the publisher recognizes the article title that they recently published (unless it’s such a huge blog with many editors) and they want to hear what you have to say about it. Is there any research conducted on what type of personalization to include in the subject line? For example, should you use the word “contribution” compared to “guest post”?

    Thanks again for the great read!

    1. Hi Joseph, thank you. That makes total sense and matches what we found: that personalizing subject lines help open/reply rates. We didn’t look into the type of personalizing that works best. But I’d say that their name, website (or as you pointed out) a recently post title can all work.

  48. Another great article Brian – the biggest takeaway for me was about adding social media profiles to the subject lines. That is something frankly I haven’t done a lot, and if the data suggests that I would get a better response- then I should !!

  49. Many of these comparisons show no statistically significant difference between the groups and yet you cite the data as if it is meaningful. Not good.

    Also, some of the charts are missing the x-axis.

  50. Hi Brian, this guide is very helpful for me. As a furniture hardware exporter, I emailed lots of cold emails to target clients all over the world, but it got few results. After reading this post, I know the header, the email body, the signature is should offer people value to outreach instead of “it is all about me”.Anyway, we should offer others convenience or value to get a reply.

    By the way, do you have any good resource on email copywriting? Thank you in advance.

  51. Wow, Brian. I can certainly tell that a lot of effort went into creating that article, and what an article it was too. I found that it was very illuminating and super helpful also. In particular, I liked the bit about the correct length of the subject line. Most helpful. So, thank you so much.

    I will save it for future reference.



    1. Thanks Simon. You’re right: Pitchbox put a ton of effort into collecting all of this data. So most of the kudos should go to them. And I’m glad to hear that you enjoyed the post.

  52. Wow. Just Wow! I like all your case studies. It provides really practical insights.
    Email marketing is the most important channel in marketing world and the kind of Outreach messages that get high response rate was a great takeaway for me. Also, the way you explained how writing a subject line little differently can change the response rate, I’ll keep that in mind before sending emails. Thanks for such post 🙂
    You are a gem.

  53. Besides the article, I have read every comment, in total 133 and you replied to each one (also a learning point for me). Since you devote so much time to research and statistical proof for the strategy and tactics you are employing in your on-line marketing, it is worthwhile to mimic what you do, and this also persuaded me to become a loyal customer.

    The feedback for this article: you know how sometimes you do these checklists in .pdf form? Executive summary could serve nicely for download, so people are reminded by the checklist, what they should actually do when writing the outreach emails, especially if this is not our every day practice.

  54. Hello Brain,

    Amazing piece of content.

    You said that correct. Email outreach still works. One must have to follow the data, which you just shared above.

    I am following your guestographics technique which is working really well for me.


  55. Thanks, Brian for sharing this such an amazing information about email outreach.

    Most people are thinking that guest posting is dead but based upon the analysis your email got a great response for guest posting and I personally think that it is still at large. What do you think?

    Have a wonderful Wednesday.

  56. Hi Brian,

    Thank you for the study.

    Quick Question:
    – When you say emailing multiple contacts increases the response rate:
    a) are you referring to adding multiple contacts as a recipient in the same email or b) sending multiple contacts separate emails?

    1. Hi Boni, you’re welcome. We’re talking about sending one contact a series of messages. Then, if you don’t get a reply, emailing another contact.

  57. Since starting to follow you, I’m seeing lots of increases in my traffic. Now, I need to go through my drip campaigns and modify them to get the best response rates. Thanks for your insight! 🙂

    1. Nice! You’re welcome Brent. To be clear: this study looked at outreach emails (not newsletter-style emails).

  58. This is great info. We personalize our emails and have had about the 8% estimated success that would be expected. I like the Saturday vs Wednesday info, I feel sorry to anyone who thought Saturday was a good day to send out a reach out email. Thank you for this info, I just recently subscribed after viewing some of your Youtube info and I appreciate all your hard work.

    1. Thanks Javier. Well, I can’t blame people for trying out Saturday, LOL. Also, thanks for your kind words. I appreciate that.

  59. Great article. Biggest takeaway is Wednesday being a good day, Saturday not. And also the longer headlines and personalization on headlines is helpful. Definitely putting it into use immediately!

  60. Dude Dude Dude, Brian, you are the gem you always add a tremendous amount of value in your posts.

    It really shows your dedication level and hard work.

    The easy to understand presentation of your post is amazing.

  61. Thanks for sharing this. I’ve got different results. I’ve sent more than 200 emails in the recent period and managed to get 8 guest blog posts, which is good. But, after that, I sent over 100 outreach emails and nothing. I will try to personalize emails as you suggest. I hope it will help.

  62. Hey Brain,

    This is amazing read & I learned quite a bit of useful information from it. I appreciate you taking the time to study, analyze, and post this data.

    I am going to repost it tomorrow!

    Best Wishes!

  63. Great research.
    But pitchbox shared the details of the emails that their customers sent out? Wow..
    I would never use pitchbox.

  64. Hey, Brian

    I’m a reagualr reader I’m always following your valuable ideas for my blog… thanks for your tips… to email outreach mistakes.. and study about…

    great job.

  65. Thanks for this study Brian!
    It aligns with everything I have experienced with my blog email outreach, especially the point regarding “personalized emails”.
    I have a short list of email subscribers right now! So, I ask them to reply back with their questions. This has helped me connect better with my readers.

  66. Really useful information, Brian. I’m with you on Wednesday as the best day of the week. I find Tuesdays quite good as well. Mondays and Fridays are the most popular days for people to take off or are just days where everyone’s workload is heavy, hence the days when my emails will most likely be ignored.

    1. Hi Hazel, that’s been my experience too. Midweek seems to be a little bit quieter in people’s inbox, which helps your outreach get noticed.

  67. Hey Brian

    I have just started my journey in the SEO field and I just have to say that I love reading your content. The precision with which you describe and prove things makes it impossible to not digest. So, thanks for all your efforts. It is really amazing and very much helpful.

  68. The Skyscraper Technique carries the day yet again! Thanks for the incredible insights, Brian.
    My biggest takeaway from this is personalization. Sending hundreds of generic emails just doesn’t work anymore.
    The social link is an interesting discovery as well. Will definitely be testing it soon.

  69. Great article Brian. My 1 big question is about multiple contacts outreach. Is this sending an email to multiple contacts at one time to try to solve who the right Buyer is, possibly via a referral? Is it just referring to trying different contacts at a company to get a better response rate for that company. I typically look at response rates by contact.

    Any clarification you can provide would be great.

    1. Thanks Ned. It’s sending to a single contact. Then, sending emails to another contact if person #1 doesn’t get back to you.

  70. Great post Brian as your other posts and I love how you always replay back on comments 🙂

    I have a question, do you recommend putting the post date in SERP?


      1. No I mean for example Yoast SEO tool lets you show the publication date in the SERP, you can enable or disable it.

        It shows the user if the content is fresh or old… I guess it could be good to show for news sites or sites that keep updating their old blog posts.

        You often talk about updating your blog posts with fresh content, do you also make the publication date visible in the SERP to show the post has been updated?

        Hope this helps what I was trying to say 🙂

        1. I see what you mean, Emin. Not to split hairs, but Yoast SEO lets you show your publication date in your HTML. Google ultimately decides whether or not to show it in the SERPs. I’ve seen lots of cases where they don’t.

  71. Super interesting blog post. Thanks for sharing! Interesting how some data totally aligned with data Salesloft shared with us… and a few are actually opposite.

    Did you (assuming you had the data) look at the B2B vs. B2C dimension in your study? I found the information on Instagram very surprising and was wondering whether this could be because of a mix of B2B and B2C emails.

    1. Thanks Olivier. We didn’t look at B2B vs. B2C. But I agree: there could be some interesting differences there.

  72. My top takeaway is that personalization always wins. It’s more effort, but well worth it. I would love to read your analysis of link building software options, if you create one.

  73. thanks for sharing the details. I got one question. The email tends to be triggered as spam if you sent bulk emails daily or send too many using the same email. How to fix this?

  74. @ Brian,

    Love this – and, I have done exactly your post – often.

    Here’s a few thoughts.

    1) Make sure the email you send to, is the email of someone whom will share, at the company you are targeting

    2) Send 2, 3, or 4 emails over maybe 2 or 3 weeks – whats the harm in sending different emails, a few times?

    3) Content of email is important – give them a reason to share or link

    4) We also contact them via Facebook (or twitter or insta etc) – email is getting outdated with some depending on biz

    5) Re read the outreach email – subject line, top to bottom, email signature – make sure it sounds good to you — would YOU share it if you received it?

    1. Nice! Great checklist. I especially like #5. It’s amazing how many people send out complete crap outreach emails because they skip this important step.

  75. Great article!

    It seems to me that personal touch is the most important part.

    For one I know I hate being approached with a generic email, that I know was sent out to at least 100 other contacts.

    Another thing I consider important is demonstrating who you are. I guess that’s partially done by including your social profiles, so people can look you up and judge if what you’re offering is worth it or not.

    Anyway, thanks for the detailed info!

  76. Thank you!
    I was actually just a little proud that my outbound campaigns checked several of these boxes, but the ones I can evaluate and improve on are:
    – providing more context/value in follow up emails
    – longer, personalized, subject lines
    – not being afraid to reach out to multiple people on the same team. I definitely get stuck in the “want to get just the right person” mindset

  77. Great post, Brian, as always! As a rule of thumb, I personally try to make my outreach emails as personal as it gets, this practice tends to bring quite high positive feedback. Also, love your follow up email advice.

  78. Brian,

    Based on your experiences, after how many days should someone send a follow-up email?

    As of now, we are sending follow-up emails after 7 days.

    Just wanted to learn if 7 days is ideal or is it too late?

    Looking forward to hearing from you.


  79. Thanks Brian, if there’s one thing I suck at it’s email outreach 🙂 Appreciate your help as always.


    1. Hi David, no worries. Outreach is hard. I hope this study makes things easier for people who might have struggled with outreach in the past.

  80. Couldn’t agree more with you Brian! Luckily, a few hacks can make your outreach campaign work like magic like personalization is key. Another thing I have noticed is that most people respond at final follow-up. Maybe it’s about FOMO, but it works.

  81. Hi Brian,
    Thanks for this great article. I’m embarking on this great freelance writer adventure, and your post will significantly help me to achieve my goals.

  82. Hey Brian
    Thanks for sharing this Blog.
    We have been struggling with low open rate, low click rate and but finally figured out that some of our emails were going into spam.
    Your insights are great, we will surely want to take decision based on the insights.
    Thank you

  83. Hi Brian,

    I have one question open:

    What is the best way to open up a sales pitch and lead the potential customer to the landingpage in a brand new Email outreach?

    No Prior Contact Whatsoever – Products fits to company

  84. Hi Dean,

    thanks for that great piece of content! If you have a larger website or magazine it might also help to just call the office and ask, who is the right contact for you. That might save time in the end.


  85. That was so helpful! I had no clue Wednesday was the best time to send out emails.
    A follow-up email is also a great idea if you really believe your content needs to be read- will definitely be trying that 🙂
    Awesome article!

  86. Good job, Brian.
    Last time I started to use different services for automating outreach process.
    1) Parsing the email addresses behind any website with
    2) Create drip campaign with
    3) A full package of instruments for email outreach in
    4) With Snovio you can find emails, verify them and run your email campaigns

  87. Hi Brain,

    This blog was an awesome resource for us. We used to send e-mail but never thought of sending up the follow-up email. That Idea could surely work for us

  88. Thanks for this.

    I would like to know if the follow up emails should come as a thread under the first one or as a single email?

  89. Thanks, great read! I see that in your subject line character count examples you’re not including spaces. Am I correct to assume that your recommended length of 36-50 characters also does not include spaces? Thanks a lot!
