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:
https://en.wikipedia.org/wiki/Email_read_receipt
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.

Thanks... i couldn't think what to look up. google on "email tracking" or receipt would have helped. In that link is in fact what i needed to know i think the email client inserts a line in the header. But one always knows that an email has arrived by 'delivery status failure' or whatever words similar which i think depends on the server.
