How can we separate Mother's Day and Father's Day from the rest of Holidat campaign, so we can send to the right people? For example: If have 1000 people in the holiday campaign (600/men and 400/women). I want them all to receive holiday greetings like Easter, 4th of July, thanksgiving, and so on. This seems to be ok until May when I dont want to send mothers day emails to my 600 men . What do I do then? Then what do I do in June for Father's Day? Then what do i do after Father's Day
