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.

Apple’s Mail Privacy Protection (MPP) went into effect on September 20, 2021, impacting Apple Mail users on iOS 15, iPadOS 15, and macOS Monterey devices, regardless of email services.

Marketers will no longer be able to see reliable open rates, open times, geolocation, or device usage for users who opt into MPP, impacting the way Apple market share is analyzed. As a result, we have broken market share information into two sections: Post- and pre-MPP launch.

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 March 1, 2024.

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.
