Pet Rescue Saga on PC is the only King game that does not have a message envelope.  You get 5 lives each time you log in, but that is it, no more.  Try refreshing your game when you've used those 5, if you are lucky more friends may have sent some.

It might be due to the information given here:

It might be that you're not receiving them in the game in the first place. I also think if you refresh the game you lose any stored messages so keep that in mind!
