April newsletter ideas to spread beauty

World Art Day (April 15)

French Tunisian artist eL Seed has said, “This is the purpose of art: To bring people together and bring back the humanity as well.” Across the world, World Art Day is a great reason and a great way to bring your customers and supporters together.

  • Showcase local talent. Art runs through the veins of many small businesses and organizations, from schools showing off their students’ creations, to local makers sharing their artistic endeavors with their customers. This World Art Day, consider tapping into the art that’s at the heart of your business or your community and shining a spotlight on it.
  • Give back. Consider partnering or raising awareness of local art-centered charities and giving your subscribers good ways to learn more.
  • Encourage creation. Have fun with it! Treat your subscribers to a wine and painting event, host a coloring contest for your young (and young at heart) subscribers, or find other fun ways to wake up the artists in your audience.

Earth Day (April 22)

Each year, EarthDay.org drives awareness and action across the globe about the health and future of this planet we call home. And because we all call it home, it’s something that all businesses and their subscribers can relate to.

  • Do good. Evaluate what your business can do (or already does) to be good, green citizens. Share your business’s plans or actions with your audience in your newsletter, then challenge them to do good and share with you!
  • Be a resource. Curate content and share simple tips and actions to make a difference.
  • Support your community. Sponsor a green space, hold a cleanup event, or have a recycling challenge! Or, partner with other businesses or community orgs already holding events, and keep your subscribers in the loop.

April newsletter ideas that make you want to get up and move

London Marathon (April 27)

  • Challenge your readers. Do a “training” challenge leading up to the marathon date for your subscribers, whether it’s running and fitness, or something related to your business and industry.
  • Support your local runners. For businesses in the UK, consider sponsoring a runner or spotlighting those in your community who will be participating in the big day. Host a “Finish Line” watch party virtually or in-person.

International Dance Day (April 30)

  • Be a resource. Use this opportunity to teach your subscribers the “steps to success” when it comes to your product, service, or industry. Supply expert tips and advice that your readers will find valuable.
  • Have fun with it. Share photos and videos of you and your teammates dancing while you work, or tell your subscribers how your business dances to the beat of your own drum.
  • Be a partner. Partner with dance schools, theater troupes, and other organizations in your community to celebrate and reach new subscribers.

TIP: Whatever holiday you highlight in your newsletter this month, whether you issue a challenge, offer advice, or ask your readers to share, include a branded hashtag and a custom hashtag — along with a corresponding post on social media — so you can easily find and like what they post!
