I've been using Mailchimp for a few years now, mostly sending out simple newsletters and mailing campaigns to my small (3k) subscriber list.
The thing that's bugging me is that my campaigns look great on a desktop, but rubbish on a phone. The reader constantly has to scroll left/right to read all the text. I've tried creating new templates, using existing templates, all sorts, but nothing seems to make much difference.
Can anyone help?
