Have you ever been troubled by the question “There are many free email services like Gmail and Yahoo Mail, but which ones should I check?” when doing HTML email design verification?
I’ll introduce a site called emailclientmarketshare.com that can help solve such concerns by showing global email client market share.
The market share for August 2015 was, from the top:
#1 Apple iPhone 29% +0.41 #2 Gmail 16% -0.58 #3 Apple iPad 11% +0.1 #4 Google Android 9% +0.4 #5 Apple Mail 8% +0.2 #6 Outlook 8% -0.25 #7 Outlook.com 4% -0.37 #8 Yahoo! Mail 4% -0.09 #9 Windows Live Mail 2% -0.04 #10 Thunderbird 1% +0.53
These results show that the top 10 clients account for 92% of the total market share.
For HTML email design verification and similar tasks, checking these top 10 clients should be sufficient.
Incidentally, the market share analysis is said to be compiled based on 1 billion open tracking data points from Litmus Email Analytics.
That’s all from the Gemba.
