Webmail surpassed mobile as the top way to read email with 48.8% of email client market share between April and June of 2020. This coincides with the start of the COVID-19 pandemic, causing people to be in front of their computers—instead of their phones—for more and varied hours. However, as the year came to a close, mobile gained ground again as the #1 way to read email.

Apple iPhone has taken back the crown with a nearly 4-point lead in global market share. Together with Gmail, these two’s dominance has increased 17% since 2019.

Apple Mail grew to be the #3 most popular email client, up from #5 a year ago. And Outlook Mobile broke into the top 10 for the first time.

Yahoo! Mail’s rank went up, but its actual email client market share went down.

Apple iPad has seen the biggest loss in email client market share, now a fifth of what it had in 2019.
