I found this amazing resource the other day when I was looking for something to help explain the importance of responsive emails to a colleague.
Free responsive email templates - Zurb Playground
An incredible amount of people consume email on their mobile phones and tablets these days – even more so newsletters and periodicals. I often save up emails like that to read when I am on the train or waiting for a bus or something ~ you can imagine how your click through rate is going to be affected if I can’t easily thumb-click the link you want me to or even read the email in the first place. It is essential to get your emails mobile ready and to help with that the smashing people at zurb have made 5 html/ css templates available to download.
Both of these are easy to get started with – let me know how you get on…
