Whether you’re a marketer or run a business, you probably agree that summertime isn’t for sadness. You can connect with your subscribers and drive sales even when they are on vacation. You could start by coming up with email subject lines and writing down newsletter content ideas.

Now, are you looking for examples of interesting summer emails? Need a refresher on summer email marketing and newsletter best practices? Either way, we’re here to lend you a hand! In our guide, you’ll find everything to make a splash with summer email marketing campaigns.

Summer email marketing holiday calendar

Before diving into the specifics, get to know the upcoming holidays and events. That’s where a holiday email marketing calendar comes in. It’s a great starting point if you want to send relevant and interesting emails in the summer.

Pride Month (June 1st — June 30th)

Pride Month is an annual celebration and commemoration of the LGBTQIA+ community that takes place throughout June. With that in mind, Pride Month marketing presents an opportunity to show support for the LGBTQIA+ community and promote inclusivity. It’s a time for advocacy, recognition, and acceptance of diverse sexual orientations and gender identities.

The Pride Month email from Starbucks ticks all the boxes. First, it features an eye-catching banner that’s relevant to the topic of the email. Second, it shows support for the LGBTQIA+ community by highlighting a relevant nonprofit organization. There’s also a CTA button that takes subscribers directly to that nonprofit’s website. 

Last but not least, the CTA button at the bottom of the message encourages readers to learn about other ways to support the LGBTQIA+ community. It makes the entire email much more effective by underlining that its purpose is both supportive and educational. 

Flag Day (June 14th)

Flag Day commemorates the adoption of the United States flag. It’s an opportunity to celebrate national pride and patriotism. You can incorporate patriotic themes into email newsletters. For instance, put the United States flag at the top of the newsletter message or come up with compelling subject lines that center around pride and celebration. Doing so creates a sense of unity and helps you connect with your subscribers.

If you need some inspiration, here’s a Flag Day email from a dinnerware company:

The heading of the Williams Sonoma campaign encourages the newsletter recipient to celebrate red, white, and blue. It makes for a nice and unique way to express patriotism. It’s not over the top. Instead, it plays into the theme of the holiday with class and elegance. To celebrate Flag Day, the company gave its customers 20% off an American flag dinnerware collection. The sale announcement is right below a photo of the collection.

Father’s Day (the third Sunday of June)

In 2023, Father’s Day is celebrated on June 19th. It’s a time to honor and celebrate fathers, stepfathers, and father figures. You can leverage Father’s Day email marketing newsletter to promote exclusive sales. Doing so is bound to resonate with subscribers who are searching for the perfect gift.

The newsletter email from quip is centered around a water flosser. It starts by creating a sense of urgency, as the special sale is going to last just one day. Then, the email outlines the benefits of the water flosser. 

The newsletter further emphasizes that the flosser is worth purchasing by mentioning that it won awards. A customer review is also used to highlight the quality of the product. Finally, the email ends with several call-to-action buttons, directing the reader to make a purchase.

Juneteenth (June 19th)

Juneteenth celebrates the emancipation of enslaved African Americans in the United States. Juneteenth email campaigns on this day can focus on promoting equality, Black history, diversity, and inclusivity.

Barnes & Noble did just that by promoting books about African American history and culture:

For starters, a colorful banner encourages newsletter readers to celebrate Juneteenth. Next, email recipients get a selection of books by African American authors. They are divided into sections, from cookbooks to novels, kids’ books, and, finally, history books. With this campaign, Barnes & Noble amplifies Black voices and educates its subscribers.

Independence Day (July 4th)

Independence Day marks the birth of the United States. With that in mind, focus on incorporating patriotic themes. Since Independence Day is traditionally celebrated with fireworks, barbecues, and gatherings, you could also promote products related to these traditions.

To give an example of an Independence Day email campaign, Spreadshirt showcases its wide selection of patriotic clothing:

The newsletter message above is written in a very positive tone. It begins with a photo of two people wearing Spreadshirt’s patriotic t-shirts. Underneath it is a coupon code for $5 off Spreadshirt’s products, which is meant to encourage readers to make a purchase. It’s accompanied by a CTA button leading to the company’s online store, as well as two patriotic headers (“Land of the free” and “More freedom-loving products”). 

In case the reader isn’t convinced, the email presents them with a few other products. This product selection includes aprons, pins, baseball caps, and other t-shirts. 

Labor Day (September 4th)

Labor Day is a public holiday that honors the contributions of workers. Although it isn’t a summer holiday, you can start Labor Day email marketing in August with exclusive sales. Make sure to highlight products or services that will help your newsletter subscribers make the most of their long weekend or end-of-summer plans.

Winc settled for offering a limited-time deal on wine bottles:

Unlike many Labor Day emails, this newsletter message is fairly simple and minimalistic. It features the company’s signature black, which brings out the email’s contents. It starts off with a header that draws the reader’s attention to a low product price. This, in turn, encourages them to make a purchase.

Under the header, there’s a CTA button and a picture of a bottle of wine in an ice bucket, as well as a discount code. Below is a fun and relatable paragraph connecting wine with Labor Day and yet another call-to-action button. It links to the company store, which makes it easier for the recipient to make a purchase.

Other email purposes to consider

Consider writing about other events that typically happen in the summer. In case you need help, read on! We created a short list of such events you can use as a handy point of reference.

  • Backyard barbecues. With warmer weather, people often gather for outdoor barbecues and picnics. Share grilling tips, recipe ideas, or recommend products that enhance the outdoor dining experience.
  • Beach and pool parties. Emphasize summer fashion trends, swimwear, beach accessories, and skincare products suitable for fun days spent by the water.
  • Summer travel. Encourage your audience to explore new destinations or provide tips for planning a summer vacation. Share travel-related content, such as packing lists, itineraries, or destination guides.
  • Outdoor sports and activities. Highlight outdoor activities popular during the summer, such as hiking, biking, camping, or water sports. Promote related gear, equipment, or adventure travel packages.
  • Music festivals. If your target audience includes music enthusiasts, promote upcoming music festivals, share lineup announcements, or give away tickets.
  • Summer reading. Recommend books for leisurely summer reading or create book club promotions. Consider partnering with authors for book signings or virtual author events.
  • Gardening and outdoor decor. Provide gardening tips, showcase outdoor furniture, planters, or tools for those interested in sprucing up their outdoor spaces.
  • Family fun. Mention family-friendly activities, such as visiting amusement parks, zoos, or local events suitable for kids during the summer break.

Using these summer events, you can add a sense of seasonal relevance to your campaigns. It should also help you create engaging and relatable content for your subscribers. Just remember to tailor the content of each email to the industry you work in. For instance, if you specialize in selling travel insurance, promoting local music festivals would probably be a bit odd.

Offer exclusive summer discounts and promotions
