I remember back about 2000 when i started using email there was a way that one could tell if it had been read. In those days i was using Outlook. How did it work?
I don't know if this is a good place to start:

I do remember some story many years ago about an email read tracking service that would have a hidden iframe with an 1x1 px image at a unique URL that would load and let a paying customer see if it was loaded. Not sure what happened to that service.
