What exactly is email client market share and why is it important?

Litmus has reported on email client market share over the years to help email marketers everywhere understand monthly market trends for email clients, like Gmail, Apple Mail, and more. Knowing these movements empowers marketers to make better decisions when it comes to strategy and prioritization for design, coding, and overall email program focus.

With Apple’s release of iOS 15 in 2021, email client data for Apple mail clients will be completely skewed, as will overall market share data. However, this page will still show trends, and as we navigate through the iOS 15 release, updates will continue to be made. For more information on this release, visit our Apple Mail Privacy Resource Hub.

Email client market share

About these stats
This leaderboard of the most popular webmail, desktop, and mobile email clients is compiled from data collected worldwide by Litmus Email Analytics, and displays figures for the top 10 email clients. These statistics have traditionally been updated each month, and are current as of September 1, 2021.

Since determining the client in which an email is opened requires images to be displayed, the data for some email clients and mobile devices might be over- or under-represented due to automatic image blocking.

Variations in market share are expected for individual audiences and demographics. More email clients can be detected using Litmus Email Analytics.
