Gmail Statistics (Updated for 2021)
Let’s start with some statistics about Gmail itself.
1. There are more than 1.5 billion Gmail users.
Google usually keeps its user counts a bit under wraps, but in a tweet in late 2018, Google confirmed that Gmail has more than 1.5 billion active users around the world—a massive growth spurt from the 1.0 billion active user profile it had in 2016. I imagine this number will only continue to grow in the future as Gmail gets better, while remaining free to individual users (and inexpensive for business users).
2. There are more than 10 million spam and malicious emails every minute, all blocked by Gmail’s automated machine learning (ML).
Phishing messages, scams, and spam emails are constantly going out—and Gmail is constantly trying to protect users from them. More than 10 million of these messages are blocked automatically by Google’s anti-abuse machine learning software every minute, which is something like 14.4 billion every day. Even if you get annoyed by the occasional stray spam message, you can rest easy knowing for every one message that slips through, there are millions you’ll never have to deal with.
3. Only 0.1% of messages that make it to the inbox are spam.
What are the end results of these efforts? According to Gmail, only 0.1 percent of all messages received by users in their inboxes are categorized as spam. That’s just 1 in every 1,000 messages. And as long as you know how to identify suspicious messages, all it’s going to cost you is a moment to hit the delete button.
4. Only 0.05% of automatically spam-flagged messages are not actually spam.
Gmail also assuaged public concerns that desired messages were landing in the spam folder, automatically flagged as spam—less than 0.05% of wanted messages land here. That’s just 1 in every 2,000 messages. Still, it’s a good idea to periodically go through your spam folder and make sure nothing important got flagged as spam.

5. About 27% of all email opens are on Gmail.
According to a 2018 Litmus study, about 27 percent of all email opens occur on Gmail, a marginal increase from 2017, when it represented 26 percent of email opens. The only email client that ranks higher is Apple iPhone, with 29 percent of email opens. Apple iPad is in third, with 10 percent, and Outlook is surprisingly low, with only 7 percent of email opens. We’ve written before about Outlook vs. Gmail, and in line with these statistics, Gmail is noticeably better.
6. Gmail offers support for 105 languages.
Do you speak Catalan? Or what about Sinhala? Gmail supports those languages. There are 105 languages currently supported by Gmail, and Google is constantly adding support for more.
7. The average Gmail account is worth $3,588.85.
According to Backupify, the average Gmail account value is something like $3,588.85. That figure is a few years old at this point, so it might be even higher now. What constitutes an email’s value? In some cases, it refers to the value of assets being transferred or held in your inbox. In other cases, it refers to the opportunity value of ongoing conversations. Either way, if you suddenly lost access to your account, you can probably think of hundreds of ways it would negatively affect your life in the short term.
8. The average Gmail user has 1.7 accounts.
Nobody has a fractional Gmail account, but on average, people tend to have 1.7 Gmail accounts. Put more reasonably, most people have more than one Gmail account—like one for business and one for personal purposes.
9. The average Gmail account has more than 17,000 emails.
You thought your inbox was bad. Does it help you to know that the average account contains more than 17,000 emails? That includes multiple folders, but still—that’s a lot of information you’ll probably never need to reference.
10. About 75% of Gmail users access their email on a mobile device.
Roughly three-quarters of all Gmail users regularly access their Gmail account from a mobile device. Mobile is quickly becoming the device of choice for email users.
11. Among Americans aged 18-29, 61% use Gmail.
By contrast, among Americans aged 30-44, 54 percent use Gmail. That percentage decreases to 36 percent among Americans 45 to 64. Interestingly, the percentage of people who use Yahoo mail tends to rise with age; only 19 percent of the youngest age group uses Yahoo mail, but 31 percent of people aged 65 and older use Yahoo mail.
12. More than 20 billion emails have been migrated to Gmail.
Gmail offers a handy migration feature, and so far, more than 20 billion emails have been migrated—more than 28 million per day. Most migrations are able to be completed in less than a day, and in many cases, just a few hours, thanks in part to Google’s intuitive and reliable migration service.
13. More than 60% of mid-sized U.S. companies use Gmail.
Even more impressive, 92 percent of startups choose Gmail as their business email provider. That’s because Gmail (and by extension, G Suite) is ridiculously beneficial for businesses, yet is highly affordable, at somewhere between $5 and $25 per user, depending on the level of your service package.
14. More than two-thirds of incoming messages are promotional in nature.
About 68 percent of incoming messages are categorized by Gmail as “promotions.” Similarly, 22 percent of messages are classified as updates. That leaves about 10 percent of incoming messages that offer something of substance.
15. The read rate for promotional emails is 19.2%.
The same study found that the read rate for promotional emails was 19.2 percent, while the read rate for updates was 28, the read rate for social emails was 22.4 percent, and the read rate for forum messages was 21.1 percent. If anything, I’m surprised these numbers are so high.
Gmail History and Gmail Facts
The following items aren’t exactly Gmail statistics, but more interesting history and facts about Gmail. Gmail has a long and interesting history, with increasing benefits for users and only a handful of setbacks along the way.
16. The first Gmail account went live April 1, 2004.
Definitely not an April Fool’s joke, Google went live with its email platform April 1, 2004. It’s the kind of thing that seems like it’s been around forever, but it’s only been in existence for 15 years.
17. Gmail celebrated its first birthday with 2 GB of free storage.
On the 1-year anniversary of Gmail going live, Google gave users 2 GB of free storage, doubling the 1 GB of free storage that was given at launch. For most users (especially casual, personal users), 2 GB is a threshold that will never be met, but for high-volume and high-profile users, this upgrade was practically vital.

18. Google consolidated its user storage in 2013, with 15 GB of free storage.
Google continued to increase the limit for a while, to 10 GB at one point, and added separate storage limits for services like Drive and Google+. In May 2013, it consolidated everything with 15 GB of free storage—which you can still enjoy today.
19. Gmail was considered the best webmail service in 2006.
As you can imagine, Gmail has won its share of awards, but it was an early contender in the email game, winning “best webmail service” by Forbes magazine in 2006. Every year, new Gmail features, add-ons, and streamlined functionalities make Gmail even more impressive and useful.
20. The longest outage in Gmail history was 2.5 hours.
So far, the longest outage in Gmail history has been in February of 2009, lasting 2.5 hours and affecting more than 100 million accounts. Considering the 1.5 billion active users of the service, it’s remarkable that Google has done so well keeping their servers reliably active.
Email is by far the most popular and common communication platform in the professional world, due to its accessibility, convenience, and reliability. These email statistics, while not specific to Gmail, help illustrate just how powerful email is as a communication channel.
1. In 2020, there will be 306.4 billion emails sent.
In 2018, there were more than 281.1 billion emails sent. In 2020, that figure is expected to grow to 306.4 billion, and in 2021, that number will grow to 319.6 billion. That’s a rate of growth of about 5 percent per year, which may not seem like a lot, but it adds up quickly. This is largely due to the increased accessibility of email and digital devices in developing countries around the world.
2. The average worker gets 121 emails per day.
Though the most recent figure here is from 2015, the average worker receives at least 121 emails per day; it’s likely this figure has only grown. What’s your plan for managing these 121 emails without getting overwhelmed?
3. The click-through-rate (CTR) of emails averages 3.1%.
The CTR of emails is declining (largely due to distrust of marketing and sales emails), with an average rate of 3.1 percent.
4. 6% of emails are opened on mobile devices.
Mobile devices remain the most popular type of device for opening and reading emails, responsible for seeing 55.6 percent of email opens.
Email Sales Statistics

2. 69% of spam flags are based purely on a subject line.
Only 21 percent of people will flag emails as spam, but 69 percent of all spam flags are prompted purely from the content of the subject line. You better make those subject lines count.
3. 24% of email opens happen within an hour.
After that, the majority of email opens still happen within 24 hours.
4. The average email user deletes nearly half of the emails they receive.
Each day, the average person deletes 48 percent of all the emails they receive.
5. Salespeople spend more than a third of their time emailing.
