Designing an HTML email that renders consistently across the major email clients can be very time consuming. Support for even simple CSS varies considerably between clients, and even different versions of the same client.
We’ve put together this CSS support in email clients guide to save you the time and trouble of figuring it out for yourself. With 21 different sets of results, all the major email systems are covered, both desktop applications and webmail.
Here’s the list of email clients we tested for the 2008 CSS guide. We didn’t see any huge improvements across the board this year (there wasn’t a whole lot of updating going on) but Entourage 2008 certainly gained some ground. Hopefully it’s a sign of things to come from Redmond. source
