Well I take your point, but we had a designer make us a really cool template, so i'm fairly sure my boss would be upset if I ditched it and went with a plain text email instead :)

It is a good point though, especially when users are downloading emails on portable devices for example, so it would be a good idea to reduce the size of the message considerably, which i'm fairly sure we could. Infact I expect its not that big, I was just using 100k as its an easy size to work out bandwidth requirements with, and to play safe.
