Narrative:

This flight was handed down to me at shift turnover with a laundry list of various mels. I was told they were all accounted for on the release; no other stories. Once [the] aircraft was airborne; I happened to notice one of the alerts that the swing dispatcher had acknowledged was for a MEL addition; specifically MEL 26-xx-xx: engine no. #3 loop B - inoperative. I also noticed that there didn't seem to be a broadcast message via acars to give the new MEL to the crew along with time/initials. I contacted the crew via acars and they confirmed that they did not receive the amendment; either via acars or voice; that they had lost track of it with all the other mels on the aircraft. Normally; I would not give a MEL amendment once the aircraft was airborne; but in this case; since the MEL had been added correctly by maintenance before departure; in fact before my shift ever started; I went ahead and sent time/initials to add the MEL.not sure [about the cause]; you would have to speak with the swing shift dispatcher. This aircraft already had 6 mels; this one made it 7; so it could very easily have been lost in the shuffle or the dispatcher overlooked sending it while dealing with the numerous other flights he was following. You would have to ask him.
