Something else that should be mentioned is that there are privacy
implications with this situation as well. I don't really want you to
know when I open your email, lest you have some marketing (or equally
sinister) motivation in mind. If you were seriously evil (read:
marketing) you could argue that opening your email established a
business relationship with me and use it as an excuse to telemarket in
a way that the Do Not Call list would allow.

That might be extreme. Bottom line is, you don't need to know when I
open your email.
