As emailing designer (and HTML integrator) I follow the strict rules regarding maximum width, fixed URL's, image tagging, font colours and inline CSS and I respect the additional limitations imposed upon us by certain email clients regarding backgrounds and the type of media and the kind of bitmaps that are allowed to go into an email. A good copy in bitesize portions is important as well, just as an unambiguous and prominent call to action.

The examples here below give you an idea of different types of newsletters or emailings. Some (such as the Vampire emailing) are done within a very limited timeframe of a few hours, creation of the HTML included.
