Ok… I’ve had an idea.
When I send out an email, i want to know if and when the recipient opens the email. I was wondering if there was a way to implement PHP into an email. I was thinking to have it record the time and email address of the person (the latter I have no idea how to do) into a MySQL table. That’d be handy 
I’m guessing, though, that there’s an existing message-tracking service available…
I don’t want to use receipts. No user intervention.
Thanks in advance! :cons:
