We’ve gotten some whispers of it already— spring is on the way.

March newsletter ideas

With the first whispers of sunshine and spring flowers, March is full of colors, vibrancy, reasons to celebrate, and occasions to educate.

Find what fits with your brand and leverage it to build relationships with your readers and your community.

March newsletter ideas for bringing awareness and educating your audience

With March being awareness month for numerous diseases and causes, from Chronic Fatigue Syndrome to vascular anomalies, it might be a good idea to use a bit of space in your newsletter to bring awareness to a cause that’s important to you, your business, or one of your employees.

  • Be a reliable resource. Share some statistics and educate your readers. You don’t have to be an expert in the subject you want to bring awareness to. Instead, get with a local expert who is willing to answer some questions, then write a blog article or do create a video to share the expert’s information. Or, find an online article on a reputable website (like I did with the CDC and John Hopkins Medical Center above) and share the links with your readers. Include a small paragraph or two explaining why you’ve chosen to share it with them and why they should read it.
  • Be involved in your community. Partner with a nonprofit organization to help bring awareness to your community. You can take a poll to see what people already know about the cause and then share the correct answers in a future newsletter or on social media. Or better yet, host a fundraiser and raise awareness and funds at the same time.
  • Be relatable. If there’s a cause or occasion this month that’s particularly important to you, create a blog post about it and share an intro and link to it in your newsletter. Get personal and let your readers in. The more open and honest you are, the more they’ll be able to relate to you — which often translates to loyalty.

March newsletter ideas for having fun

Spring is coming. Go ahead, celebrate! Have some fun with your newsletter while driving traffic to your website and social media pages.

  • Share stories. Write a blog article telling a funny background story about your business, or a family adventure that relates to one of this month’s ‘holidays’. Then, share the link to it in your newsletter, along with a line or two from the article that will tease and entice your recipients to go to your blog to read more.
  • Create downloadables. With this month celebrating both flowers and crayons, this is the perfect month to use tools like Canva to customize some floral coloring pages and share them with your readers. HOT TIP: Incorporate your logo into the design and then use these same pages to entice new website visitors and Facebook followers to join your mailing list.
  • Create an online challenge or contest. Challenge your readers to complete a scavenger hunt based on one of the many March holidays. You can start with a trivia question whose answer provides the next clue. With tools like puzzle.org or quickhunts.com, this can be something you host locally or online for more participants. You can even hide extra hints on your website and give your newsletter readers a leg-up on the competition by telling them where to look for the hints.

Whatever holiday you highlight in your newsletter this month, whether you issue a challenge, offer advice, or ask your readers to share, include your social media links and any branded hashtags or custom hashtags you’ve created so readers can easily find your social pages and relevant content.
