How does a one way transmitter ensure the message is received? Does the sender just have to hope the recipient is in range at the time of sending?

With one way pagers, there is no way to ensure the message is received. The transmitters can be hundreds of watts and the signal is narrow band and uses forward error correction. As long as the pager is on and in the coverage area, there is a pretty good chance the message will get through. The signals will penetrate much deeper into buildings than cell signals. Of course if you are underground or in a shielded room the signal will not get through and you will not know that you missed a message.
