Majority of Email Opens Take Place on Mobile Devices Studies Show

Over the last year we have seen multiple studies from firms like Experian Marketing Services and Yesmail showing an interesting and important trend: the number of people opening their emails on mobile devices continues to rise, with 50 percent or more email opens occurring on the mobile platform.

As the year comes to an end, yet another study by Return Path, yields similar findings. Their research shows that in December 2013, 51 percent of email opens happened on some kind of mobile device. The study also marks the first time ever that Return Path has observed mobile email opens getting a majority of the platform share.

Most notably, the highest percentage (62 percent) of mobile email opens occurred over Christmas, likely caused by the deluge of holiday greetings and shopping transactions made by consumers. Perhaps

Similar Findings by IBM: Online Shopping

Further supporting this, IBM also reported having 48 percent of all online shopping traffic coming from mobile devices on Christmas day. Results are up by 28.3 percent compared to Christmas Day in 2012, while also surpassing the traffic share of last year’s Black Friday and Cyber Monday shopping blitzes. Mobile also accounted for 29 percent of all online sales on Christmas Day for IBM, showing a significant increase of 40 percent compared to last year.

Other noteworthy findings by IBM include a clear pattern—and a continuing trend—indicating more purchases happen on tablet devices, with browsing occurring predominantly on smartphones. IBM’s research shows smartphones account for more traffic compared to tablets, at 28.5 percent and 18.1 percent respectively, but account for only half as many sales, at 9.3 percent and 19.4 percent respectively.

More Shopping Traffic on iOS than Android

Another interesting find by IBM is how iOS devices reportedly drove more than twice as much shopping traffic, compared to Android devices on Christmas Day, at 32.6 percent versus 14.8. Return Path also showed a similar disparity, this time on the email front. The market research firm found that 86 percent of mobile opens happened on an iOS device on Christmas day—58 percent of opens occurred on an iPhone, 28 percent on an iPad.

A similar study by Movable Ink also found a major imbalance between emails opened on Android and iOS mobile devices.

More Findings

It also comes as no big surprise that Return Path found that the majority of email messages on mobile devices were opened on weekends and holidays, while emails opened on traditional desktop computers spiked during Mondays. In other words, mobile opens happened when people were away from work, and desktop opens while at work.

For Internet service providers (ISPs) and email service clients in the United States, vast increases in email opens occurred on Gmail in December, which Return Path correlated to a recent change Google made to display images, which are now enabled by default.

If anything, these findings show what we’ve been telling our clients throughout the previous year, that is, not to forget to design emails for the mobile format. Mobile email opens are no longer just a trend—they’re here to stay, and will only continue to grow.
