Is there a difference between a reliable message delivery system and a guaranteed message delivery system?

There is:

A reliable message delivery system uses a protocol and/or a reliable transport mechanism and depending on its scope, it retransmits messages which failed (for a few times) to arrive or even persists messages between sessions/restarts.

Apart from the realm of marketing departments, there is - in contrast - no such thing as a guaranteed message delivery system. You doubt? Simply detonate the receiving/transmitting/both box while the message is being transmitted. It will never arrive.
