People around the world send and receive emails all day, every day. It's a common form of communication in the business world. It's also necessary for everyday internet life since many websites require an email address to create an account. But, how many email users are there worldwide, exactly?

There were more than 3.8 billion email users during 2018, according to a recent Radicati Group study. That means over half of the planet uses email right now. Radicati expects that number to reach 4.2 billion by the end of 2022.

The Radicati Group's estimates have been a bit high in the past. It's possible the real number will fall short of their projections.

How Many Email Accounts Are There?

Since many people have multiple email accounts, the number of worldwide email accounts is growing at a faster pace than the number of worldwide email users, Radicati said. The average number of email accounts per user ratio was about 1.75 in 2018. By 2022, that ratio will reach 1.86 accounts per user.

The number of active email accounts around the world was around 4.4 billion in 2015, which is up from 2.9 billion in 2010 and ~3.3 billion in 2012.

How Many Gmail Users Are There?

Google had over 1 billion monthly active users in early 2016. In May 2015, they had 900 million users worldwide, which was even higher than their 2012 report of around 426 million monthly active users.

How Many Outlook.com Users Are There?

In early 2018, Outlook.com had a reported 400 million active users. However, that number hasn't changed as drastically as the Gmail statistics.

How Many Corporate Users Are There?

Both consumer and corporate users comprise the Radicati Group's estimate of 3.8 billion email users in 2018. Because it isn't clear how the email accounts are differentiated between consumer and business users, it's hard to measure the statistic's accuracy.

In 2010, the Radicati Group reported 730 million business email inboxes worldwide, which at the time, was 25% of all email accounts.

How Many Emails Are Sent Each Day?

About 281 billion total business and consumer emails were reportedly sent and received per day in 2018, and that number will reportedly grow to over 333 billion in 2022.
