People spend more during holidays, so tying your email campaigns to key dates throughout the year works especially well for e-commerce brands. Technically, almost every day is a celebration 🎉 But not all holiday campaigns are a good fit for all industries and customers.
For your convenience, we’ve picked the most important and interesting holidays for email marketing campaigns for each month of the year. Use our holiday marketing calendar — and grow your business with flying colors!
What is a holiday marketing calendar?
A holiday marketing calendar is a year-round schedule of holidays, shopping events, and observances your brand can build campaigns around. For ecommerce, it helps you plan promotions, email content, and other marketing activities so you never miss a high-intent date.
Why you need a holiday email marketing calendar
You probably know some email marketing milestones like Black Friday or Christmas by heart — why do you need a holiday calendar? A calendar can help you improve your emails in several ways:
- It makes planning easier. If you have an email marketing calendar, you can come up with a content plan for the entire year and start working on content copies in advance instead of cramming overnight.
- It helps you keep track of everything. Especially if you’re a solopreneur with no employees to do all the marketing for you! A calendar will bring some structure into your life and make it easier and less stressful.
- It makes your email strategy more intentional and aligned with your brand values. The choice of holidays can be an important part of your brand image and policy. Everyone sends Christmas emails — what about Blue Monday? Use the calendar to create outstanding email campaigns and give your subscribers interesting and relevant content no one else has done before.

- Blue Monday (the third Monday of the year, Jan. 19th) It’s often described as the most depressing day of the year (even though the “formula” behind it isn’t scientific). Use it as an opportunity to cheer up your customers with discount codes or uplifting articles from your blog.
