10 best tips for creating an engaging September newsletter

Before diving into September newsletter ideas below, let’s first look at some tips you should follow when creating a newsletter.

The most important rules are:

  1. Fuel customer engagement: Tell your brand’s story, offer loyalty programs, and showcase noteworthy social moments to generate interest.
  2. Create a strong subject line: A compelling subject line entices your recipients to open the email, so craft it carefully to grab their attention and hint at what’s inside.
  3. Maintain consistent email branding: Consistency in design, fonts, and colors ensures your subscribers can easily identify your emails in their inbox.
  4. Make it easy to read: Use clear and concise language, break up text with headings and subheadings, and use bullet points to improve readability. A cluttered layout can discourage readers.
  5. Give customers an effective CTA: Every newsletter should have a clear CTA that guides readers on what they should do next. Whether it’s to click a link or make a purchase, the CTA should be compelling and easily visible.
  6. Consider your mobile audience: Make sure your newsletter is mobile-responsive, with a layout and font size that’s easy to read on smaller screens.
  7. Offer exclusive incentives: Give your subscribers a reason to stay subscribed. Exclusive offers, discounts, or early access to content can incentivize them to stay engaged with your emails.
  8. Keep the layout simple: A cluttered design can overwhelm readers. Stick to a clean, organized layout that directs the reader’s focus to the most important content.
  9. Use high-end visuals: High-quality images and graphics will make your newsletter visually appealing.
  10. Test before sending: Check for broken links, formatting issues, and how the email appears on various devices and email clients. This ensures a smooth and error-free delivery to your subscribers.

September newsletter ideas

When creating a newsletter it’s crucial to understand who your audience is. Age, marital status, place of residence, interests, needs — all of this makes a difference to the information they want to receive. Remember, the more information you have about your audience, the easier it will be to personalize your newsletters.

Don’t send the same email to all the subscribers on your list. Use email personalization to cater to the specific interests of each recipient. There’s no need to reinvent the wheel here. Personalization can be very basic, like using their first name or location. You can also go deeper and use information from the recipient’s purchase history and other behavioral data. This tactic will help your engagement grow. 

This is also where national or international days come into play: you can use them as part of a personalization effort. That being said, let’s dive into major September events and newsletter ideas you could adopt.

September 1: National Lazy Mom’s Day

Being a mom is one of the most challenging jobs in the world. This holiday is a reminder to give all moms a well-deserved break from their daily tasks. The only permitted chore on this day is to sit back and relax. 

Newsletter idea: There are never too many gifts for mothers, and September 1 is no exception. You can send newsletters with gift ideas or offer discounts on products for mothers. Congratulate them on the fact that their children are finally going back to school and they will have more personal time again.

September 2: World Beard Day and World Coconut Day

The second day of September celebrates two things: a man’s favorite accessory and a critical piña colada ingredient. There’s something about a beard that makes people admire and respect it, so it deserves its own day of celebration. As for World Coconut Day, the main goal is to educate people on the numerous benefits of this fragrant fruit.

Newsletter idea: September 1 was all about mothers, so on the second day of September you can give some appreciation to men. If you sell men’s beard or skin care products (that contain coconut oil, for example), it’s a great day to greet customers and offer them some coconut-related products.

September 4: Labor Day

This day not only celebrates the achievements of American workers but also marks the unofficial end of summer. It’s a public holiday, so people get to enjoy an extra day off by celebrating Labor Day with picnics, sports events, and street parades. 

Newsletter idea: This holiday is a perfect opportunity to offer end-of-summer deals to your customers or help them get ready for fall by introducing a new collection. If you want to add more color to your email, use traditional red, white, and blue in the design. Images or emojis related to the US (flag, monuments, famous places, etc.) are also welcome as they will draw the attention of your customers. You can even include a message that shows your pride in being an American.

September 5: International Day of Charity

A day that spreads awareness about charity and why it’s essential to help those in need. This special holiday provides an ideal platform for various charitable opportunities to happen.

Newsletter idea: Tell your customers about foundations and charity organizations your brand supports, and encourage them to participate by donating. If a percentage of sales from your products goes directly to a charity, highlight that in a newsletter to your customers and share the story. Here is an excellent example from Haus Labs by Lady Gaga:
