A Must-Read Resource For Every Email Marketer

Way back in March of 2006 I raved about Campaign Monitor's A Guide To CSS Support in Email so I was thrilled to see that they've done a follow up for 2007 called, appropriately, A Guide to CSS Support in Email: 2007 Edition

It's been just over 12 months since I posted our original Guide to CSS Support in Email and quite a bit has changed since. Sadly, the most significant of these changes was in the wrong direction, with Microsoft's recent decision to use the Word rendering engine instead of Internet Explorer in Outlook 2007. We've written plenty about it already including an explanation of the reasoning behind it. More on its impact on CSS support later.

It hasn't all been doom and gloom though, a number of vendors have maintained or improved their support for CSS, especially in the web-based email environment. The new Yahoo! Mail looks very promising and the old Hotmail will be making way for the new Windows Live Mail in the coming months. Desktop based apps tend to move a little slower and not a great deal has changed on that front, but traditionally they've been the best performers anyway. This year we added Outlook 2007, the new Yahoo! Mail and Mozilla Thunderbird for the Mac to our test suite, and also noticed some subtle changes in others.

If you are interested in what you can and cannot do in email formatting you really need to read this and bookmark it for future reference.
