I came across an interesting article from Marketing Profs recently with the latest email marketing statistics based on device.

If we apply this to email marketing, it shows that the digital age is here and mobile devices have taken over. This means more emphasis should be put on the message and design of an email, and less on the day and time it is sent. An email is likely being read on a small screen while the viewer is on the go, not sitting at a desk. Therefore, make sure your email marketing content has a clean look and concise message built for multiple devices.
