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.
