Number of e-mail users worldwide from 2017 to 2023 (in millions)

Despite the growth and prominence of mobile messengers and chat apps, e-mail is an integral part of daily online life. In 2018, the number of global e-mail users amounted to 3.8 billion and is set to grow to 4.4 billion users in 2023.
Global e-mail audiences In 2018, approximately 281 billion e-mails were sent and received every day worldwide. This figure is projected to increase to over 347 billion daily e-mails in 2023. Recent industry data shows that the trend towards mobile also holds true for e-mail: in December 2018, 43 percent of e-mail opens were via mobile. Desktop e-mail clients’ open share had declined to 18 percent, and webmail accounted for 39 percent of opens. Based on the dominance of mobile, it is no surprise that the iPhone e-mail app was the most popular e-mail client, accounting for 29 percent of e-mail opens. Gmail was ranked second with a 27 percent open share. Gmail is a free e-mail service owned by Google, and the company reported 1.5 billion active Gmail users worldwide in October 2018.
Malicious mail Many online users use e-mails for website and newsletter signups and brace themselves for the inevitable flood of spam and marketing communications. Whereas most unwanted e-mails are annoying yet ultimately benign, consumers are right to be wary of malicious e-mail that can be used to compromise their digital accounts and devices. Overall, consumers are pretty aware of the dangers of unknown e-mails and according to a global survey in February 2019, 45 percent of internet users reported that they avoided opening e-mails from unknown e-mail addresses.
