The problem if I understand correctly is that email was never intended to support embedded HTML but plain text (just as HTML was never intended to evolve to what it is today, beyond using it for sharing scientific information). I can't recall where I read it but sending a page to be rendered in an email is considered an aberration and one of the reasons to do that is for advertising/spam (and now also scam) purposes.
