If you'd had no contact at all with someone for over a decade one would expect them to get crossed off the list, otherwise you'd still be sending Xmas cards to people you last spoke to in 1965. Services? You're telling me there are people who cannot even be bothered to write out their own Christmas cards? As far as I'm concerned if you don't write them yourself you might as well not bother sending them, because you can't care that much about the person they're going to. I know you said your family sends out "over a hundred", but how many of them actually need to be sent? No one has that many friends and family.
