I created several EDM marketing emails for a client of Thomas Leger design consultants. The client supplied the designs in InDesign. I then recreated them in Dreamweaver (remember that program) and passed on to the client for posting.
The layouts were tested in various email clients to ensure a consistent look.
Links within the e-shot were small summaries to lead to pages on a small website rather than put all of the content within the e-shot itself.
