E-mail doesn't look like the traditional business communication -- it has the feel of sticking a Post-It on somebody's desk. E-mail can be sent without a lot of reflection. Most employees don't really think of the fact that when you send an e-mail there will be a copy on your computer, the network backup tape, etc. It's frequently harder to get rid of an e-mail than a written document.
