There is one thing for which a "read" status is very useful is so you know your message have actually been received. One big gripe I have with email is that with some providers, is that unless I receive a reply or a bounce, I never know if my email was actually received. Was it ignored? Sent to the spam folder? Though now that I think of it, you could have a lying "read" status, where everything that is sent to the spam folder is marked as "read".
