Becasua Christmas is coming, I want to send Christmas emails to friends.
This would be a good time for you to start.
We usually send our Christmas emails a few days before Christmas, perhaps the 28th or 19th of December. However, if the person is using a work email address and they won't see your email until after the holidays, then we prefer to send the email earlier.
Thank you, Andi and Bruce. Merry Christmas to you!
