We gathered the most recent and relevant email marketing statistics for 2023 – knowing them will push you to the front of the pack in the new year.

Let’s dive right in!

Email is it.

If you’re reading this, you probably have a hunch that this is true, but let me tell you there are plenty of statistics to back that up. Here’s one for starters:

The total number of emails sent and received in 2022 was more than 333.2 billion. Already in 2023, the number is at 347.3 billion.

So with all of these emails going every which way, that means a lot of people have email addresses, right?

The number of people who use email is at 4.3 billion currently.

With the total population of earth being around 8 billion, that means if you put all of the people on the planet together, more than half of them have an email address.

But, is there any room for growth? Apparently!

The number of email users is expected to be more than 4.6 billion in 2025. That’s an average increase of 100 million per year over the next 2 years.


That’s what most marketers see when they think about the future of email marketing.

So, if your organization is not using email to communicate and market to clients, you’re missing out. And there’s no time like the present to start!

Think about the amount of time every day Americans spend just checking their email. As of 2021, people spend 321 minutes each workday. What?!?

Furthermore, according to the DMA, the average ROI for email marketing is $36 for every $1 spent.

With a ROI like that, you can see why email marketing is worthy of your attention. Because of this tremendous potential, a person sharing their email address should not be taken lightly.

The average value of an email address is $113.48.

Email marketing statistics for 2023: What you need to know

As you can see, we’ve already shared some fascinating figures. Now, let’s get into more data and look at the most important changes and trends in the email industry.

What has changed in email marketing in 2023?

First, it’s worth taking a second to understand the impact on email of the pandemic, lockdowns and the Great Resignation.

Many businesses have decreased their operating hours, while some closed their walk-in spots to become strictly online. Lockdowns, increased restrictions, unemployment, and changing consumer habits have contributed to many changes to email.

Email became the main lifeline between businesses and their customers. It’s the number one channel companies used, in 2022, to share updates and important announcements.

Are we in the inbox? Deliverability could use a boost

Landing in the inbox is every email marketer’s goal. Nonetheless, many senders are struggling to arrive there, as you’ll see in the stats below.

  • According to current data from Talos Intelligence, 84.82% of all emails are spam. Russia was the most significant source of unsolicited emails. Global spam rates are on the rise again, though: in 2012, 69% of the world’s emails were spam.
  • In 202, the average spam rate around the globe was 0.01%. Keep in mind that a natural email spam rate is less than 0.1%, meaning one complaint for every 1,000 emails.
  • The average deliverability is 78.67%.  That means for every 100 emails sent, an average of 21 don’t make it to the inbox.
  • 31 billion emails bounce every day.
  • 16% of all emails land in the spam folder.

It’s a big assumption that when you send an email, it goes into the inbox. Sometimes it ends up in spam, and other times, it doesn’t get delivered at all.

Your delivery rate refers to the number of emails that reached a server, which could be either the spam or the inbox folder. Your deliverability means the number of emails that made it to the inbox.

Open rates: How do you stack up?

Ask any email marketer and they’ll tell you the metric they care the most about is their open rate. For good reason: open rates tell you a lot about the quality of your content and also, the health of your email list.

Here’s what statistics say:

  • The average open rate across all industry types is 21.33%.
  • Government-related emails lead the pack at a 28.77% open rate.
  • Emails relating to hobbies follow at 27.74%.
  • Emails about religious matters come in third place at 27.62%.
  • Germany has the most engaged subscribers. The country’s average email open rate is 40.67%.
  • Companies sending one newsletter a week can expect an average open rate of 33.40%.
  • Plain-text emails tend to get higher open rates than HTML emails.

With all of this in mind, remember there are things that can help increase your open rate.

Bonus tips: Make sure the content you send is resonating with people. Also, finding your best sending frequency is crucial. Finally, email hygiene is a must for maintaining a good sender reputation and landing in the inbox. If your bounce rate is higher than 2% and your opens are low, you know it’s time to give your list a scrub.

We break for click rates

Your click-through rate (CTR) is another significant metric to keep an eye on. The CTR is the percentage of your email subscribers who clicked your content at least once. It means they not only thought your email was worth opening, but something you communicated compelled them to click.

Knowing the average CTR is valuable knowledge.

  • The average click-through rate across all industries is 2.3%.
  • Education emails get the best click-through rate at 4.4%.
  • Real estate and design related industries do especially well at 3.6%.
  • Outdoor related industries, like agriculture, forestry, fishing and hunting, also get a respectable CTR of 3.4%.
  • Construction, contracting, and manufacturing get a rate of 3.2%.
  • Smaller lists perform better. Email lists of 1,000 to 2,499 subscribers have the best click-through rate: 3.98%. Databases of 2,500 – 4,999 people come second with a CTR of 3.35%.
