Timing of Sending Mailers During the Holidays?

[STRMLDR]

what is your experience on sending mailers and closing stuff during november and december? is it pointless? do you get an average response?
what about sending them say mid december and timing it so they get it at the beginning of the new year?
please advise
thanks

i have never steadily mailed them, but i am about to start to and am looking at timing
