Why Doesn’t My CSS Work in the Campaign I’m Sending?

Updated on: February 24, 2015 Category: Campaign Building, FAQ, Troubleshooting

Make sure your CSS is inline rather than in HEAD or BODY tags.

Browser-based email applications (Yahoo, AOL, Hotmail) strip CSS out of HEAD and BODY tags by default, so unlike web browsers, many email clients won’t properly render CSS inside HEAD and BODY tags.


Since BODY tags are stripped, in order to change background color of an email, you must put a 100 percent wide TABLE wrapper around the mail.
