Email is a delay/disruption tolerant network, and each hop in the network has a positive acknowledgment that the message has been committed to stable storage (a high bar). If the final destination rejects the message a delivery failure message is sent to the originator if one was specified (it's not mandatory), otherwise the postmaster is notified.
In general, I think whatever you are suggesting will not have all the same guarantees of delivery as email.

ACK is not to guarantee that messages are delivered though. It's a mechanism that ultimately would let the sender know the message was most likely not delivered.
