January sales email calendar.

A January sale needs its own plan separate from Christmas, with a clear start, a clear end and a defined audience. Announce early to your best customers, open to the full list next, and close with a last chance email, so the sale feels like an event instead of a permanent discount.

Key dates (UK)

  • From Boxing Day through January, with brands choosing their own start and end

Last reviewed 12 October 2026. Dates are calculated from the rule for the day, so they stay correct each year.

Why it matters.

Shoppers expect reductions after the holidays, so the question is how to take part without training your list to wait. A sale that has a reason, such as clearing a season or a stock reset, is easier to defend than one that simply exists.

January is also when budgets are tight and attention is split, so shorter emails and a single clear offer usually serve readers better than a wall of products.

Common mistakes.

This is a planning structure, not a promise of results. Your offer, stock, list and shipping options decide what is right, so test and adjust.
