I have specified background-color for the body of my email email.
It works in all desktop clients - according to design testing - but not in Yahoo Mail, Mail.com, Earthlink and AOL Web.
Does anyone know a trick to force these to display background-color?
Yahoo Mail, at least, definitely supports background color - see http://www.campaignmonitor.com/css for our test results.
Perhaps you are doing something tricky with your code, or have a typo somewhere?
Me tricky? Nah...
Seriously, no, nothing unusual at all.
Anyway, I'm just going to try and also apply bg color to the overall containing table (if that makes sense) as well as to the body.
New test shows that worked.
