Well there are other ways to know if the email was opened. Google shows for example http://www.returnreceipt.com http://www.msgtag.com/Mail_Receipt_.html
These use the feature called "web bugs" http://en.wikipedia.org/wiki/Web_bug to let some server know when the mail was opened. Users with better security knowledge may prevent this from working. I suspect some of them likely exploit the poor security on windows which might let them run programs by just open the email.
