67 special events to inspire your December newsletter ideas

Sales Manager, Andreea, working from Barcelona.

Love it or hate it—it’s that time of year again! Get ready to deck out your email campaigns with some fresh new content for December (hint—there’s a lot more going on than just Christmas and NYE)!

Yes, the end of the year is upon us, meaning it’s time to add some Christmas cheer and New Year’s joy into your email marketing campaigns (cue the repetitive festive songs). But laying Christmas newsletter ideas aside, there are plenty of other special dates and occasions during the holiday season to inspire your next email, from the Winter Solstice to Green Monday. 

Zip up your puffer jacket—or put on your shades, depending on the hemisphere 😎—and let’s sleigh-ride into these 67 December content ideas. 

Before you get started…

Remember that relevance is key. Pick events that relate to your business in some way—even if it is as simple as adding a P.S. to remind your readers of the special day. 

Bear in mind that some of these days hold special cultural and/or religious significance, so if you choose to refer to them in your newsletters, remember to be sensitive and considerate. 

Use this as a guide to help plan your email newsletter calendar for December. We encourage you to experiment and to keep it Lite!


1. Hanukkah newsletter (28 November—6 December 2021)

Beginning on 28 November, Hanukkah also plays a starring role in our November newsletter ideas guide. This year, the Jewish festival draws to a close on 6 December this year, with candles being lit, and people sharing traditional games and meals with their loved ones.

  • Newsletter idea: Wish all of your subscribers a happy Hanukkah, and suggest 10 ways they can share the love during this holiday season 

2. Christmas newsletter (25 December 2021)

A religious and cultural festival celebrated by people worldwide, Christmas is a time to gather the family, exchange gifts and eat a special meal together, with special traditions including Santa Claus, Christmas trees, carol singing, holiday sales and more.

  • Newsletter idea: Set up a Christmas campaign with a time-sensitive coupon and gift guide in the run-up to the big day, along with a festive GIF to catch the eye

In this Christmas email example from Paravel, they promote their selection of perfect gift ideas—"Sustainable and Santa approved.”

3. Boxing Day newsletter (26 December 2021)

Celebrated the day after Christmas, Boxing Day is known for its big sales—although it originated as a day to offer gifts to the poor. Some countries (including Germany, Poland, Romania, Scandinavia and the Netherlands) also celebrate the 26th as a second Christmas day.

  • Newsletter idea: Encourage your subscribers to give back this Boxing Day, listing some relevant nonprofits 

In this newsletter example, J. Crew uses the humorous slogan “Get yourself the things they forgot - we won’t tell” to share their Boxing Day discounts.

3. Safe Toys and Gifts Month

In the US in 2010, 251,700 toy-related injuries had to be treated in emergency rooms. Since then, there have been widespread campaigns to improve toy safety and precautions—especially during the holiday shopping season.

7. Operation Santa Paws

This month is all about recognizing the value animals and pets add to our lives, but also raising awareness for the many that end up in shelters after Christmas, as people underestimate the responsibility of caring for a pet.
