For the past 8 years I have been receiving Christmas cards addressed to an incorrect name. It annoys me so much, I'd really rather not get a card at all.
As gently correcting the (repeat) offerders on my name clearly isn't working, I'd like to just tell people to not send me any cards at all.
I'm preparation for next year I'd like to figure out how can I do this in a forceful but polite way.
