I've talked to a few families that claim their invitations never arrived. I know the addresses were right, but they must have have gotten lost in the mail. Out of 65 invitations, at least 2 completely disappeared in transit and were never even returned to sender.
I guess the point of my post is two-fold:
1) To find out what ratio of disappearing invitations everyone else had.
2) To serve as a PSA that sometimes invitations get lost, so always follow up with your invited guests.
