“Do you remember… the 21st night in September?” I wonder if when Earth, Wind and Fire wrote that song they were singing about the International Day of Peace?

Whether or not they were singing for world peace, September 21st is indeed a day to celebrate and strive for peace on Earth. But that’s just one of eighty (yes, 80!) special events we’ve compiled to inspire your September newsletter ideas.

From events that hold cultural significance like Hispanic Heritage Month and World Afro Day, to our favorite goofy unofficial holidays, like Talk Like a Pirate Day, you’ll find plenty of ways to keep your subscribers engaged in this September roundup.

Before you begin…

Remember that relevance is key. Pick newsletter topics 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 email marketing strategy, remember to be sensitive and considerate. 

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