The Top 10 world ranking email clients
If you're an email marketing specialist you'll almost certainly know Litmus for their awesome email analytics tool and great insights. We've featured them several times before, including this great infographic showing trends of Email client share. Here is the latest update from their Email client market share site which they update each month.
We would probably expect Apple to be dominating due to the surge of iOS mobile devices and growing popularity of Apple devices, though it's interesting to see that Outlook is still popular and it reminds us of the importance of testing the effectiveness of designs for Gmail on different clients. When interpreting these results, we need to bear in mind variation across desktop and mobile usage and demographics which Litmus have in their other reports.
Litmus collated over 835 million email opens worldwide, to share these trends. We know that it's only an estimate, due to image blocking email previews across different clients but a good source of statistics, to use with other sources to keep on top of trends.
