Email user statistics: 2022–2026

According to a study that has been tracking email user statistics since 1993, the number of email users is set to hit 4.37 billion worldwide in 2023. This is a 2.7% increase from the previous year and represents more than half of the global population.

Analysts expect this number to continue rising in the coming years, growing by 2.5% to 4.48 billion in 2024 and another 2.5% to 4.59 billion the following year. By 2026, the number of email users worldwide is projected to hit 4.73 billion.

In other words, in just four years, the number of people using email around the world is forecast to grow by 11.1%.

How many people use email: top drivers

According to experts analyzing email user statistics, this increase is driven by both consumers and businesses, both of whom rely heavily on email as part of their online experience. Personal users, for instance, are often required to use their email accounts to gain access to online platforms like social media sites

It’s also not uncommon for some personal users to have multiple accounts, each for a different purpose. In fact, experts estimate that the average email user in 2022 had 1.86 accounts.

Meanwhile, businesses—especially ecommerce businesses—depend on email marketing to communicate with their customers. In this regard, key uses include notifying buyers of their orders, sending shipping updates, reminding them of unfinished purchases, and more.

The growth in the number of email users is in line with the number of emails sent and received per day, which is also set to increase over the next few years and top 392.5 billion by 2026. 

That said, what email service providers do most people use? The most popular email client worldwide is Apple Mail, the go-to choice of more than half (65%) of all email users worldwide. This is followed by Google’s Gmail, with 24%. The third most popular email client is Microsoft Outlook. At 3.4%, its market share is just a fraction of Apple’s.
