I was surprised by this claim as well -- my current expectation is that
i have *no idea* when my mail reaches the receiver's mailpile (and i'm
fine with that, tbh).

I know folks involved in heavy statistical marketing analysis and other
forms of user tracking and "customer management" like to believe that
they know when people open their mail, but i think most users actually
only know that someone got their message when they get a reply (or a
phone call about it).

Eleanor, where do you see the "existing user expectations" around
delivery status?
