October email calendar for Shopify stores
October 2026 email calendar for Shopify stores: key dates in the US, Canada, UK and Australia, eight send ideas with subject lines, and how to set up November.
Key dates, October 2026
October has two key dates and one big job: getting your list ready for November.
It's also the quiet month that the holidays are measured against. Adobe compares holiday demand with October spending: on Cyber Monday 2025, US online sales of Bluetooth headphones and speakers were up 1,850% on their October average (Adobe), and across the whole season video game sales were up 415% on October levels (Adobe). Whatever you sell, November and December will look nothing like October. Use the calm to prepare.
Australia is heading into spring and summer, so seasonal angles flip for Australian customers.
Breast Cancer Awareness Month is only worth an email if your brand gives to a related cause all year. A pink product in October with no link to a real donation reads as borrowing a cause. If you do give, say how much and to whom.
| Key dates, October 2026 | 2026 | Where |
|---|---|---|
| Breast Cancer Awareness Month begins | Thu Oct 1 | US |
| Canadian Thanksgiving | Mon Oct 12 | Canada |
| Columbus Day | Mon Oct 12 | US: federal holiday, not a sales moment |
| Autumn and back-to-routine | All month | US, CA, UK |
| Halloween | Sat Oct 31 | US, CA, UK, AU |
| Diwali (gift sends start in late October) | Sun Nov 8 (NYC DOT) | Where relevant to your customers |
Take it with you
Eight send ideas
1. Autumn routine reset. "Your October routine, sorted." Education, no discount.
2. Canadian Thanksgiving hosting. "Hosting this weekend? Start here." Canada only.
3. Best sellers, with reviews. "The three things people reorder most."
4. Founder note. "Why we make it this way." Builds trust before November's noise.
5. Halloween. "Nothing scary in here." Only if it fits your brand.
6. Black Friday early-access signup. "Want in before everyone else?" The most important October email.
7. Gift guide preview. "Holiday gifts, sorted early." For gift-heavy stores.
8. Winback. Lapsed customers, before the Black Friday rush crowds the inbox. See the winback flow.
How to write the early-access email
This is the one October email that pays off in November, so give it care:
- Promise something specific. A day's head start, first pick of limited stock, or a gift with the first orders. "Exclusive access" on its own means nothing.
- Say when. Black Friday 2026 is Friday, November 27, 2026. Tell people when their access starts, even if you haven't set the offer yet.
- Make joining one click. A button that adds them to the early-access list, not a form.
- Send it twice. Once in mid-October to everyone, once in late October to people who opened but didn't join.
Get November ready now
Next: November email calendar.
- Clean your list, so November emails reach engaged inboxes. People who haven't opened in months can go into a winback flow or be left out of November's sends.
- Grow your early-access segment.
- Check stock on likely best sellers.
- Set shipping messaging for gift buyers.
- Check your welcome flow works, because new subscribers from your early-access form will arrive all month.
- Decide your Black Friday offer now, not the week before. The free BFCM planner dates every step back from November 27.
Plan it with Tilly
The email calendar plans October from the dates for your store's country. A US store gets Breast Cancer Awareness Month from Thursday, October 1, 2026, Columbus Day, Halloween and Amazon's Prime Big Deal Days, which the calendar treats as a window rather than a date because Amazon announces it each year. A Canadian store gets Thanksgiving and Halloween; a UK or Australian store gets Halloween. Every send comes with a reason, and you can switch off any date that doesn't fit your store. Planning the month costs no credits. Building every email in it costs 8 credits an email, and each one waits for your approval before it goes to Klaviyo as a draft. To try the dates first without connecting anything, use the free email calendar generator.
