A print publication won't support an animated gif. Since a print publication
by definition means it will be printed that only makes since. A web
publication would support an animated gif, though they are easy for the user
to break the animation. And I'm thinking that even converting a web to email
may do just that. And I'm thinking that even if the latter is not the case,
that it is likely the receivers email client would kill the animation, as
email clients lock down on html email in the name of security. Because of
security concerns and email client compatiblity differences email should be
plain text not html. If you need to send a richer format then send pdf's.
