Since our built-in HTML editor does not offer advanced features to handle Cascading Style Sheets, designing the message in an external HTML editor can be especially useful if you make extensive use of CSS. If you use Cascading Style Sheets, however, remember that not all email clients offer the same support for CSS (e.g. background images are not supported in Outlook 2007, among other things) and that typically external CSS documents are not supported. All CSS styles need to be defined inside the message.
