One basic problem with trying to do anything "fancy" in an e-mail (i.e., anything other than plain, simple text) is that you have absolutely no control over the program that the recipient uses to view the e-mail. They could be using Outlook 2003, Outlook 2007, Outlook Express, the Gmail Web-based interface, the unique Web-based interface provided by a particular ISP (Internet Service Provider), etc. Each of these programs typically handles the "fancy" things (e.g., embedded images, stationery, etc.) in a slightly different way.
Additionally, the options that the recipient uses in viewing their e-mails (e.g., plain-text display rather than HTML display) affects the appearance of that e-mail on the receiving end
. That is, what you see when you send the e-mail is not necessarily exactly the same thing the recipient will see when they receive and view your e-mail.
Below are some links about animated GIF files in e-mails:

Even seemingly simple links in e-mail can cause problems. Again, this is usually due to the program that the recipient is using to view the e-mail, and the settings of certain options in that e-mail program.
