Email Open Rates: A Scientific, Step by Step Guide for 2021 (2022)

Post summary:

  • The success of your email campaigns depends on email open rate. If no one opens your email, then you cannot generate new business from email marketing. So, what is a good email open rate?
  • We share open rate numbers by industry, by device, by out send time and more – all backed by research from 50 email marketing statistics to help you increase email open rates.
  • Withour unique case study, we show you how we earn an average 40% email open rate for every single email we send (based on over 99,000 emails sent). Plus, learn how we generated a 94% email open rate!

How do you measure the success of your email campaigns?

The chances are that you measure the success by the number of people who open the mail (email open rate) and the number of people who click on a link (click-through rate).

That's how I used to measure it.

And while there's nothing wrong with that, what gets overlooked is that the click-through rate is entirely dependent on the open rate, because unless people open your email, there’s no chance they can click on it!

Therefore, in order to get a better click-through rate, you need people to open your email.

So, how do you get more people to open your email?

There’s a lot of opinions on the web about how to increase email open rates, but I’m only interested in the concrete data behind email open rate success - which is why this article is stacked fullof more than 50 email marketing statistics!

Since launching SuperOffice Marketing,we've helped thousands of companies useemail marketing to engage with their subscribers.It's also given us access to data and insight onhowpeople open, respond and engage with email campaigns - which we'll be sharing in this report.

The science and data presented to you in this article will help you get more people to read your email marketing campaigns and help you increase email open rates, which in turn positively impacts the overall performance of your email marketing strategy.

But, first...

What is an email open rate?

Before I dive into the data, you and I need to understand this metric. You see, most people consider the open rate as the number of people who open your email.

Sounds logical, right?

Unfortunately, that's not the case. An email is only counted as opened when one of the following occurs:

  1. The reader enables images in your email to be displayed in the preview pane or in a full view of the email.
  2. The recipient clicks a link in the email.

OK, easy enough. But, how are email open rates calculated?

Email service providers (ESPs) calculate the open rate by taking the number of people who open the email and dividing it by the number of emails sent that did not bounce, i.e. failed to reach the recipient.

For example, if you send 100 emails, and 10 of them bounce, this leaves you with 90 delivered emails. Of those 90 emails, let's say that 10 are opened. This means that your email campaign open rate is 11% (10 emails opened from 90 delivered).

Emails that are not delivered cannot be opened, which is why this number is not included in the open rate percentage.

What is the average email open rate?

Given that B2B email marketing has been the most popular marketing channel for several years' and that the average number of promotional emails sent to readers continues to increase, you would think that email open rate is on the decline.

For the most part, that wasn't the case.

Between 2015 to 2018, the average open rate for email was steady - hovering at 24% globally.

However, in 2020, the average open rate dropped to 21.3% (a slight decrease compared to 2019).

Email Open Rates: A Scientific, Step by Step Guide for 2021 (1)

Does a decrease in email open rates signal the death of email marketing?

Of course not.

It's not the first time open rates will fall and it's not the last time.

The good newsis that based on historical data, we can see that each time thereis a decrease, it's always followed by a strong period of growth. So, we can expect to see an increase again in 2022.

Before you get more people to read your emails, you first need to understand where you stand.

How many people currently ready your emails? What is your current email open rate?

This is where industry benchmark open rate reports comes in.

How do I compare to the industry average?

Benchmark reports are important in understanding of how the industry is changing on the whole and you should find out your own benchmark based on your email campaign performance. You should be able to pull this number from your email service provider.

Here's a look at our own open rates based on an email campaign we ran back in 2020:

Email Open Rates: A Scientific, Step by Step Guide for 2021 (2)

As you can see, open rates differ from country to country.

How do your own email open rates compare?

In 2020, the average open rate across all industries was 21.3%. In 2021, the overall average open rate dropped again and stood at 16.97%, with a 10.29% CTR.

When it comes to your individual results, numbers may differ. After all, you know your email subscribers better than anyone else. For example, if you consistently reach a 15% open rate, which is below average yet your campaign is delivering results, it's obvious that you are not under performing even if the "industry average" says you are.

Of course, averages are to be taken lightly. Open rates in the insurance industry, for instance, differ from those in the health care industry. And open rates in Europe differ from those inNorth America.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (3)

The first challenge you need to work on is getting your email to your subscriber list. It’s no use spending hours crafting a perfectly optimized campaign if it ends up in your readers’ spam folder, is it?

How do I get more emails delivered?

Think about this:

More than 20% of marketing emails never make it to a subscriber’s inbox. That's more than one in five emails!

Of course, just like open rate, average deliverability rates differ by region.

For example, only 66% of emails reach a reader's inbox in Asia compared to 86% in Europe.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (4)

This makes a huge difference to your email open rates!

So, how can you make sure your emails are delivered to your readers?

Here are a few tips on how you can increase delivery rates.

  • Use double opt-in. Double opt-in means that the subscriber will verify that she wants to receive emails from your business (although this not a requirement under GDPR). You don’t want to send emails to people who don't particularly care about them; otherwise, they will not read them and lower your open rates.
  • Ask your readers to add you to their trusted address book. By simply asking your readers to add the "from" email address to their contact lists, you can increase the number of emails delivered.
  • Cleanse your email list. If a subscriber does not open an email from you three times in a row, the chances are that she is no longer interested in your company. Gmail and Yahoo Mail are smart enough to understand this, so if you continue to send emails to subscribers who do not open them, they might be directed to the spam folder, so consider cleansing your list (like JD Whetherspoon did before GDPR).

The more emails that are delivered to your audience, the better chance you have of getting more people to open them.

How do people read my email campaigns?

The way people read emails can provide key insights in how you create your email marketing campaigns.

For example, the type of device they read it on.

Marketers' can no longer ignore mobile and tablet devices.

Email open rates from mobile devices have grown by more than 100% since 2011and the percentage of open rates from mobile continues to grow eachyear!

Email Open Rates: A Scientific, Step by Step Guide for 2021 (5)

Today, 81% of all emails are now opened and read on mobile devices.

Can you guess what your readers do when you send them an email that isn't optimized for mobile?

They delete it. In fact, 80% delete the email immediately!

And companies are realizing the importance of email marketing optimization. As many as nine in ten businesses are developing a strategy to optimize their email layout.

Worse still, our own email marketing benchmark report found that only 20% of email campaigns are optimized for mobile devices.

Have you seen how your own email campaign templatereads on a mobile device recently?

If not, you should take a look. If you haven't optimized your email campaigns for mobile devices yet, now is the time.

When should I send my email campaign?

Timing is important to open rates. To know when to send your email campaigns, you have to know your audience.

If you sell software, most of your customers will be enjoying family time on the weekends. That means sending an email campaign on the weekend will lead to fewer opens, if any at all!

So when should you send your email?

Research by Get Response found that the best day to send emails in order to get the highest open rate is on Tuesday.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (6)

Now that you know on which day to send your emails, what about the time of day?

Further research shows that subscribers are most likely to read your email at either 10am, after they arrived at work, or at 1pm, whenthey are catching up on their emails after lunch.

And that 23% of all email opens occur during the first hour after delivery.After 24 hours, an email's chance of being opened drops below 1%!

Email Open Rates: A Scientific, Step by Step Guide for 2021 (7)

As you see, the timing of when you send your email is crucial to the success of your campaign. If you send it on a day when people are less likely to read your email, then you could be missing out on a lot of interested customers.

So, when it comes to sending out your email campaign, Tuesday, after 1pm. is your best bet.

How do I increase email open rates?

The sender name and subject line of your emails are the most important factors in getting them opened and read.

For example, our own research found that 45% of subscribers say they are likely to read your email because of who it’s from, and 33% of email recipients open an email based on the subject line.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (8)

What sender name do you use?

Do you send your emails from company XYZ, or do you use a specific person's name?

Believe it or not, but thiscan make a huge difference!

(Video) Cold Email Tutorial For Beginners (Step By Step Guide) 2021

Research from Pinpointe marketing found that by using a specific personal name, rather than a general email address or company name, you can increase open rates by as much as 35%!

Which is why it's surprising to find that that our own B2B email marketing research found that 89% of email marketing campaigns are sent from a company name.

When it comes to subject lines, have you heard the phrase "you should spend as much time writing your headline as you spend on writing the content"?

Well, the exact same phrase applies to your subject line.

A well-crafted subject line shouldn't be the first thing you think of. Instead, it should take time. And you should use research and data to help guide you.

A report by Retention Science found that subject lines with 6 to 10 words deliver the highest open rate, making 8 words an ideal number for a subject line.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (9)

If a subject line is too long, it will get cut off and your reader will not know what the email is about (and could ignore it).

This is especially important for mobile readers as the subject line character length is even shorter - which is why more than85% of subject lines are shorter than 90 characters!

Another reason for opening an email is if the subject line is addressed to the recipient, as subject lines personalized with a recipient’s first name, for example, can lift open rates by as much as 20%!

Personalized subject lines are still popular, but the results have dropped in 2019.

There is only a 2% improvement if you use personalized subject lines. Today, it’s not enough to add “Hey John” to your subject line to increase open rates. What’s important is how relevant and compelling your message is.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (10)

Using a recipients name in a subject line is simple, if you use a CRM.

Of course, if you are feeling super creative, you can take it one step further.

Retention Science found that subject lines with movie titles and song lyrics have an average open rate of 26% (Tweet this!)!

Here's some ideas for you to start testing with:

  • Subject line #1: "Imagine all the people..." got free shipping today!
  • Subject line #2: Gone with the wind? Book your summer vacation now
  • Subject line #3: 10% discount on all products! I'm all shook up, uh huh huh

(OK, they might be a little lame, but hey I tried!)

If you link to a video within your email, you can also include the word "video" in your subject line. It's something we have tested and including the word video increased our open rates by 6%!

Are there any words I should use or avoid?

By analyzing billions of emails sent and opened, Dan Zarellawas able to find out which words to use and which to avoid in the subject line.

Here's a look at the findings:

  • Most clicked-on emails include these words in the subject line: "secrets", "e-sales" and "awesome".
  • Emails mostly reported as spam included the words "confirm", "features" and "upgrade".
  • People are less likely to open emails that include a question mark (?) or a hashtag (#).

Creating the perfect subject line that includes key words proven to increase open rates, and sending the email from a known sender should now be at the top of your to-do list for when you next send out an email.

But wait, what about emoji's? Should you use emoji's in your email subject lines?

Well, according to the latest research from Neilsen, the answer is no.

The research compared email subject lines sent with and without an emoji in the subject line and found that emojis in subject lines increase negative sentiment toward an email and do not increase the likelihood of an email being opened

(Video) Step-by-Step Guide on How to use Email Marketing as a Sales Tool

"...all things being equal, adding an emoji to the email does not make people more likely towant to open that email"

Email open rate case study

By now, you're probably thinking:

"Steven, this sounds really great, but does it work?"

And you know what? If I was reading this article, I would be thinking the same thing!

The good news is that I've tested the science. And it works!

Earlier in the post, I referenced that the average open rate in 2019 was 22.15%.

Using the techniques listed above and based on data of more than 99,000 emails sent during the last 10 months, my average email open rate is 40.9%.

That's right - 40%!

That's 85% higher than the average open rate.

Email Open Rates: A Scientific, Step by Step Guide for 2021 (11)

If you're looking to increase your own email open rates, then try one or two ofthese techniques the next time you send out a campaign!

Howimportant is segmentation?

Earlier this week, I conducted an email campaign test.

In the test, I sent two emails. The first email was sent to a segmented list (based on interest) and the second was sent tomy mainblog subscriber list.

The subject line was the same.

And the email content was the same.

Upon viewing the results, the mainblog subscriber listgenerated my average response of a 40% open rate.

I was happy.

But, what happened next blew my mind...

The segmented list earned a staggering 94% open rate!

Email Open Rates: A Scientific, Step by Step Guide for 2021 (12)

The sad part is that 89% of marketers do not segment their email list.

Perhaps now is a good time to start segmenting your lists?

(On a side note, the campaign also generated a 30% click-through rate. Improving your click through rate starts with the design. Use these B2B email marketing examples to help you craft a template that's designed for maximum clicks.)

Conclusion

So there you have it!

I’ve provided the science behind email open rates and the ways you can use the data to make actionable decisions about your email marketing.

Here’s the key points for you to take away and use the next time you send an email to increase email open rates:

  • Use 6 to 10 words in your subject lines to get the best open rate
  • Send your email campaigns during the work day and after lunch
  • Personalize subject lines with the reader's name
  • Use a recognizable sender name
  • Optimize your email campaigns for mobile
  • Bonus: Segment your email lists

Of course, the best option for you might not be to use any of the above. It depends entirely on what your reports tell you. But you can start with the data provided in this post and use the science to guide you to more get more emails opened.
