I'd rather have a "successful delivery response". It's enough to know that the email was delivered to a device you are responsible for. Tracking who's opening it and when seems a little creepy, also you'll have false positives if the email is blind forwarded. Having worked with attorney's. "I didn't get the email" is common. I'd like just to have a list of the response codes from their server to prove that they accepted delivery.
