Recently MailChimp posted about their mobile e-mail research . A lot of people read their e-mails on cell phones – 57% in Japan and 41% in the US, so it starts to be a bit consideration.
Lots of suggestions on the report:
- Use a instapaper URL link to make it easy for people to read your e-mail later, on the desktop.
- Avoid single columns that require left-right zooming.
- Apple recommends a font size of 17-22pts.
- Have big, easy to click buttons instead of tiny links on your calls to action.
- On two column templates, have a smaller left column – otherwise your reader might not see that there is a right column.
- On Gmail, the head element is removed so only inline CSS works. It also cuts content at 102 KB.
