Back to school email calendar.

Back to school is a window, not a date, and it starts earlier than many stores expect. Begin with a checklist email in late July, follow with category edits, and finish with a last minute list, timing each send to the school calendar of the region you sell to.

Key dates

  • Late July through early September, with timing that varies by country and school calendar

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

Why it matters.

School start dates differ by country and often by region, so a single national date can leave half your list behind. Where you have location data, use it. Where you do not, ask in a preference centre.

Parents and students buy differently, and so do teachers. A single email rarely suits all three, so segmenting by who is shopping is worth the extra effort.

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.
