Microsoft also released another email client for Windows 8. Windows Mail market share is expected to decline, as it no longer ships due to being replaced by Windows Live Mail. Windows Live Mail, the successor to Windows Mail, is slightly more popular with 3% market share - enough to place it at #8 on our list, right above Google’s Gmail webmail client. Despite being a deprecated email client, Windows Mail still enjoys 2% market share, placing it at #10 in our top ten. Windows is the world’s most popular operating system, which translates into free software shipping with it being popular as well. Both clients are free and relatively easy to use, making them a popular choice for consumers using Windows.

Windows Mail shipped with the Vista operating system, but was replaced by Windows Live Mail when Microsoft released Windows 7 and Windows Live Essentials. Windows Mail and Windows Live Mail are desktop email clients shipped with Microsoft’s Windows operating system.
