The short answer: The best Christmas email campaign ideas for a Shopify store follow the calendar: a gift guide straight after Cyber Monday (30 November 2026), a shipping cut-off reminder in the week of 14 December, gift cards from 18 December, a short Christmas Day greeting, then a Boxing Day sale and a New Year email on 1 January 2027.
Below: the 2026–27 dates, ten email ideas with subject lines to adapt, a day-by-day plan, and the segments that keep December sends out of spam.
Key Christmas and New Year dates for 2026–27
December emails are driven by two things: the holidays and your carriers' last shipping days.
| Date | Moment | What it means for your emails |
|---|---|---|
| Monday 30 November | Cyber Monday | The end of BFCM. Christmas emails start the next day. |
| Friday 4 to Saturday 12 December | Hanukkah | Early this year. Send any Hanukkah gift email by the start of December. |
| Thursday 17 to Saturday 19 December | USPS recommended send-by dates (lower 48) | First-Class Mail 17 December, Priority Mail 18 December, Priority Mail Express 19 December. |
| Friday 18 to Wednesday 23 December | Royal Mail last posting dates (UK) | 2nd Class 18 December, Tracked 48 19 December, 1st Class and Tracked 24 21 December, Special Delivery Guaranteed 23 December. |
| Thursday 24 December | Christmas Eve | Last-minute digital gifts only. |
| Friday 25 December | Christmas Day | A short greeting, no hard sell. |
| Saturday 26 December | Boxing Day | Post-Christmas sales start. In England and Wales the bank holiday moves to Monday 28 December. |
| Thursday 31 December | New Year's Eve | Year-in-review or a last offer of the year. |
| Friday 1 January 2027 | New Year's Day | New Year offers and "fresh start" content. |

When should you start sending Christmas emails?
Start the day after Cyber Monday, Tuesday 1 December 2026. Your list has just had a week of Black Friday offers, so open December with something useful rather than another discount: a gift guide. If you are still planning BFCM, our Black Friday and Cyber Monday email calendar covers November day by day.
December then has three phases: physical gifts until about 18 December, gifts that still arrive in time (gift cards, pickup, express delivery) until 24 December, and from 26 December, people buying for themselves.
10 Christmas email campaign ideas, through to New Year
1. The gift guide (1 to 4 December)
Group products by who they are for ("for the cook") or by budget ("under $25", "under £50"). It helps undecided shoppers and needs no discount. Link each group to a Shopify collection.
Subject line idea: "Gifts for everyone on your list, sorted by budget".
2. A Hanukkah email, if it fits your customers (by 3 December)
Hanukkah begins at sundown on Friday 4 December this year, three weeks before Christmas. If your products suit it, send a short gift email at the start of the month; if not, skip it.
3. Your bestsellers (week of 7 December)
A plain "what everyone is buying" email does the choosing for people. Only mention low stock when it is true.
Subject line idea: "The 5 gifts our customers are buying most".
4. The shipping cut-off reminder (week of 14 December)
This is the email your customers most need from you in December. Give your own last order date for Christmas delivery, based on your carrier's date minus your handling time, and put it in the subject line or the preview text. Send a short reminder the day before it.
Subject line idea: "Order by 16 December for Christmas delivery".
5. Last-minute gifts: gift cards and pickup (18 to 24 December)
Once standard shipping closes, switch to gifts that still arrive. Shopify gift cards are available on all Shopify plans and reach the customer or recipient by email with a unique code (Shopify Help Center). If you have a shop or studio, pickup in store is another option to promote.
Subject line idea: "Too late to ship? Send a gift card by email".
6. A customer thank-you (around 21 December)
A short note from the founder, with no discount, thanking this year's customers.
7. The Christmas greeting (24 or 25 December)
A few lines and an image. Add holiday opening times and how to reach you, nothing more.
Subject line idea: "Merry Christmas from all of us".
8. The after-Christmas sale (from 26 December)
Boxing Day is on Saturday 26 December, and the UK bank holiday falls on Monday 28 December, so a sale that runs from the 26th to the 28th covers both. Lead with the offer and the end date, and feature things people might have wanted but didn't get.
Subject line idea: "Our after-Christmas sale starts now, until Monday".
9. "Spend your gift card" (27 to 31 December)
People who received your gift card over Christmas already intend to shop with you. Show them what their card could buy: new arrivals, or products under your most popular gift card value.
10. The New Year email (30 December to 2 January)
Pick one angle. A year-in-review email ("what you loved in 2026") suits New Year's Eve. A "fresh start" email about goals or routines suits 1 or 2 January. Keep any New Year discount to a short window.
Subject line idea: "New year, new [routine / wardrobe / kitchen]: our picks".
A day-by-day Christmas to New Year email plan
Here is how the ideas fit together for a store that ships in the US or UK. Move the cut-off dates to match your carrier and handling time.
| Date (2026–27) | Send to | |
|---|---|---|
| Tuesday 1 December | Gift guide | Engaged subscribers, then the wider list |
| Wednesday 2 December | Hanukkah gifts (optional) | Everyone, or customers who bought Hanukkah items before |
| Tuesday 8 December | Bestsellers | Engaged subscribers who haven't bought this season |
| Monday 14 December | Shipping cut-off reminder | Everyone you email regularly |
| The day before your cut-off | Last day to order | Subscribers who opened or clicked in December but didn't buy |
| Friday 18 December | Gift cards and pickup | Non-buyers this season |
| Monday 21 December | Customer thank-you | Customers who bought this year |
| Friday 25 December | Christmas greeting | Engaged subscribers |
| Saturday 26 December | After-Christmas sale launch | Everyone you email regularly |
| Monday 28 December | Sale last call | Openers and clickers who didn't buy |
| Wednesday 30 December | Spend your gift card / year in review | Recent customers |
| Friday 1 January 2027 | New Year email | Engaged subscribers |
That is 12 sends over five weeks, but no subscriber gets all of them: the "send to" column keeps volume reasonable.
Who should get which Christmas email?
- Engaged subscribers (opened or clicked recently) get the full sequence, and get each email first.
- Recent buyers should be left out of "last chance" emails for an offer they have just used. Send them the thank-you and the gift card email instead.
- Repeat customers are the right audience for the thank-you note and early access to your after-Christmas sale.
- Subscribers who have never bought get the gift guide and bestsellers.
- Long-inactive subscribers are best left out. Mailing them at peak volume raises complaints and hurts delivery for everyone.
Christmas email subject line ideas
Clear and specific beats clever in a crowded December inbox. Ideas to adapt:
- Name the deadline: "Last day for Christmas delivery is Wednesday".
- Name the person: "Gifts for dads who say they want nothing".
- Name the price: "20 gifts under £30".
- Say what changed: "Shipping has closed, but gift cards haven't".
- Keep greetings short: "Happy holidays from the [store name] team".
- Be plain after Christmas: "The after-Christmas sale: up to [your offer] off".
Put the date or the offer in the preview text, and keep subject lines short enough for a phone screen.
What to check before December starts
- Your automations. Abandoned cart, welcome and post-purchase emails do much of December's work. Check they are on and don't promise a delivery date you can't meet.
- Your sender authentication. Google requires anyone sending more than 5,000 messages a day to Gmail accounts to use SPF, DKIM and DMARC and support one-click unsubscribe (Google email sender guidelines).
- Your discounts. Create the codes in Shopify (Discounts in your admin) before you schedule the emails, with start and end dates that match the email copy.
- Your shipping message. Use the same cut-off date on your site banner, product pages and emails.
How tinyAlbert plans Christmas and New Year emails for you
tinyAlbert is an AI email marketing app for Shopify stores. It plans a year of campaigns, writes them and your core automations in your brand's voice, and sends them. Its AI campaign calendar is built from your store's category and the retail moments in your market, so the Christmas season is already mapped out when you open it. In our test store it had queued campaigns including "Christmas sale", "Christmas Customer Appreciation", "Merry Christmas", "After Christmas sales", "Resolution Inspiration" and "Exclusive New Year's Discounts", each written for the store and waiting for review.
- Review, edit or regenerate. Each campaign has a desktop and mobile preview, an editor, a test send and a Regenerate button for a fresh AI rewrite.
- Set the dates yourself. Schedule any campaign for a date, time and time zone, so you can move sends to fit your own shipping cut-off.
- Your tone and language. Emails are written in one of 7 tones of voice and 10 languages you choose at set-up.
- Ready-made segments. Pre-built segments such as New customers and Frequent buyers help you send the thank-you and sale emails to the right people.
- Automations included. Abandoned cart emails pull in the shopper's own cart products, and welcome and thank-you emails switch on with one toggle.

Frequently asked questions
When should I send Christmas emails?
Start on 1 December 2026, the day after Cyber Monday, with a gift guide. Send your shipping cut-off reminder in the week of 14 December, switch to gift cards and pickup from about 18 December, send a short greeting on Christmas Day, and start your after-Christmas sale on Boxing Day, 26 December.
What are good Christmas email subject lines?
Good Christmas subject lines say exactly what is inside: a deadline ("Order by 16 December for Christmas delivery"), a recipient ("Gifts for dads who say they want nothing") or a price ("20 gifts under £30"). Keep them short enough for a phone, put the offer or date in the preview text, and treat every idea as a starting point for your own voice.
What is the last day to ship for Christmas 2026?
It depends on your carrier and service. USPS recommends sending by 17 December (First-Class Mail), 18 December (Priority Mail) or 19 December (Priority Mail Express) within the lower 48 states. Royal Mail's last posting dates run from 18 December (2nd Class) to 23 December (Special Delivery Guaranteed).
What should I send after Christmas?
Send an after-Christmas sale from Boxing Day, 26 December, with a clear end date, then a "spend your gift card" email to customers who received one, and a New Year email around 1 January. After Christmas people shop for themselves, so feature what they might have wanted rather than gifts.
Can tinyAlbert write my Christmas and New Year emails?
Yes. tinyAlbert's AI campaign calendar includes Christmas, after-Christmas and New Year campaigns written in your brand's voice. You can preview, edit, regenerate and reschedule each one, then switch it on, alongside abandoned cart and welcome automations that keep running through December.
