Use of mobile email clients is set to surpass desktop and webmail client usage by July, according to the results of a recent study by our friends at Return Path. After examining data from over 90 email clients, amounting for more than 130 million data points over a 6 month period, Return Path found that while webmail clients overall are on a slow decline, mobile views increased by 82.4% over the same period (March ’11 – March ’12). Mobile devices currently claim 16% of overall email client market share, with 85% of mobile email opens occurring on an Apple iOS device. This is comparable to our earlier findings.

Return Path also found that there is an uptick in mobile email readership during the weekend, which can be attributed to email recipients switching from the desktop to a smartphone outside of office hours. Conversely, it’s at its lowest on a Wednesday, when presumably folks are at their most busy tackling their Outlook, or OSX Mail inboxes.

The implications for email senders like you and I are fairly clear. As Tom at Return Path states in his summary:

“… those that aren’t tracking which device their subscribers are reading their emails on, or optimizing their emails or websites for mobile devices stand to lose out.  A poor user experience could mean no response, no action, or plainly put, no ROI.”

If you aren’t already optimizing your emails for mobile, now is the time. To set you on the right path, we’ve got a practical primer on email design, not to mention a neat template builder which can whip together mobile-ready campaigns in a matter of minutes.
