MailChimp’s Other Mobile Features
Mobile email templates
All of MailChimp's templates are mobile friendly right out of the box. You shouldn't have to think about whether or not your campaigns will look good on your subscribers' screens.
Mobile style editor
Easily adjust your template’s mobile view using the Mobile Styles tab in MailChimp’s Email Designer. Designers can code their own responsive email templates and set up editable CSS blocks, so subscribers can adjust scaling for their mobile devices.
MailChimp's preview feature has a mobile tab, so you can see what your campaign looks like on a small screen before sending. You can even push a preview to your own mobile device using MailChimp Mobile.
