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?
If it was set up on the email client then somehow it could check on the server that it was sent to. I've used gmail UI for a long while now but i was wondering if there was something in the header on each email that one could check. One has received: IDxxxxxxxx and i wondered if from one of those digits was the signal.
