Did you know that the first email ever was sent 50 years ago? Half a century later, people have developed a strange love-hate relationship with electronic mail. Many of them check their emails first when they wake up, but an even higher number of people aren't happy with the volume of emails they receive daily. This communication channel has become an inevitable part of our lives and has been steadily popular in marketing. The question is, how many email users are there?
In 2020, the number of email users reached the 4 billion mark, which means that over 50% of the world's population was using email. The latest reported number in 2021 exceeds 4.1 billion. For the next three years, the predicted user growth rate is 3%, or around 100 million more each year. So, in 2024, the number of email users worldwide should be approximately 4.5 billion.

This figure includes both consumer and business emails. In 2022, the number of emails sent daily will grow by 4.3%, resulting in 333.2 billion emails a day.

Since the global pandemic started, remote work and online interactions have surged, and the volume of email grew 7%. The highest increases in volume were reported in March and July of 2020.

The number is changing by the minute, but since we have the data on how many email users are there, as well as the average number of accounts, the estimation is there are about 7 billion email accounts. The number of email users worldwide is growing as email usage by age penetrates in groups younger than 15 and over 65. When we add the factor of multiple accounts per person, the conclusion is the number will rise steadily over the years.

Considering how many people use email, it's no wonder cybercriminals are using it as one of the main delivery methods to get to them.
In April 2020, Google revealed an enormous increase in spam emails because of the pandemic. There were 18 million daily malware and phishing emails in one critical week and 240 million additional COVID-19-related spam emails. One of the principal reasons Gmail's number of users is continuously increasing is that Google successfully blocks 99.9% of spam emails, including phishing. However, as email can be a huge safety liability, you'll need to use some kind of email encryption software if you want to protect your data. This is especially relevant for businesses.

As smartphones are becoming our primary devices, open rates for emails on mobile grew to 81%. The importance of mobile-friendly and optimized content for various devices, in general, has never been higher.
