The primary way readnotify works is though the use of iframes, not web bugs. To say that is NOT to say that readnotify does NOT use webbugs. Instead, it's to say that web bugs are not the primary way. Iframes are the primary way because they are harder to defeat than web bubs. Email isn't very good for nuance, is it?

This method is easy and :works on all platforms (Linux/mac/pc). If you use a mail :client that doesn't auto download referenced images, then the :the server hosting the image can't tell you have read the :message.
