Ignas, CEO of MailerLite.

The month of March is about to get more interesting for your subscribers thanks to these special events that you can add to your newsletters.

Thinking up new content ideas all the time is a lot of work so we have a shortcut for you! Take inspiration from these upcoming events in March and watch the new ideas roll in.

From National Women’s History Month to Tolkien Reading Day, there are plenty of March newsletter ideas to keep your email content fresh and engaging. There’ll also be some March email subject lines to get your creative juices flowing (and boost those open rates)!

Before you begin…

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. 

Some of these days hold special cultural and/or religious significance, so if you choose to refer to them in your content marketing strategy, remember to be sensitive and considerate. 

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