Your Black Friday calendar ends on 2026-11-30.
December has 3 fixed dates nobody writes down: the shipping cutoff, the window after it where only gift cards work, and the stretch between the holidays.

That is every email you have before 2026-11-27, October sends included.
Now count what the plan asks for.
