Sizzlin’ hot summer newsletter ideas for 2024

Quite the opposite—summer is a time to bring new life into your email marketing campaigns!

Use this season to complete long-overdue email maintenance tasks, shake up your content, and play around with your summer newsletter design.

Go get a refreshment and find a shady spot. We’re about to summerize your newsletters.

There are as many summer newsletter ideas as there are ice cream flavors, especially when you take into account all of the bank holidays and special occasions. 

So when you’re running out of ideas, why not use an event to create newsletter content year-round?

The biggest summer happenings to mark on your email calendar are Father’s Day, the 4th of July, Labor Day, and the last and first day of school.

And if that’s not enough, no worries.

At some point in time, someone, somewhere decided that July would be Hot Dog Month, August 3rd Watermelon Day, and August 6th (wait for it) Fresh Breath Day.

Malaysian booze delivery service Boozeat celebrated our personal favorite, World Martini Day on June 19th, with this newsletter.

Design

Color: Summer means COLOR! Bring out the brights, the lights, the tropicals, the neons, and the pastels. Summer is the ideal time to experiment with different color palettes and tones, just make sure that it fits your branding plus, choose a theme and stick to it to remain consistent. Here are some examples of Summer color palettes you can use.E

Using bright colors enhances your click rate. Try styling your buttons in yellow—this color not only gives off major summer vibes, it’s also recommended by psychologists to stimulate curiosity. This is why people tend to click yellow buttons more. Discover more color hacks in our blog post on what colors are best for email marketing. 

Typography: The fonts you use in your template designs are an excellent way to imbue your emails with the fun, carefree vacation vibes that make Summer so great. For best results, keep the main content of your templates the usual font that you use and experiment with the fonts used in your graphics or headlines. 

Background: Set the mood and inspire subscribers with Summery colors and imagery for your email template backgrounds. Yellows, oranges and blues are great if you want to go for a solid color, while tropical plants, beach scenes, and summer landscapes are images that make and impact.

Content

Summer is all about relaxing, having fun, and making the most of the beautiful weather—it’s a happy time! You want your email intro, headers and main content to use language that reflects this, connects with the reader, and inspires them.

Adjusting your tone of voice to be more casual and friendly is a nice way to do this, but only if it’s appropriate for your brand! You’ll also want to sprinkle in Summer-themed language, references—and if you’re a bit cheesy like we are—some fun Summer puns.

Imagery

Your images, icons and patterns should all play into the Summer theme. Use beautiful photos to make your subscribers feel warm and fuzzy. There are plenty of great photos online that you can use for free (check our blog post about the best free resources for beautiful newsletters). Our tip? Use your own photos to be more personal. Some ideas for imagery include:

• The beach/sea

• Swimming pools

• Plants/flowers/palm trees

• Fruit

• Swimwear

• Sunglasses

• The sun/sky

• Cocktails

• Grilling/al fresco cooking and dining

• Ice cream

• Travel

Interactive elements

Swimming, jogging, dancing, hula-hooping—summer is all about movement! Put some action into your summer newsletters and play around with GIFs, videos and countdown timers.

Accessibility

A lot of people already read their newsletters on mobile devices. Once the temperatures rise, this number will only increase. Make sure your newsletter is responsive and uses bright, contrasting colors so the content is easy to read outside. Check out this email accessibility guide to learn more.

With the hustle and bustle of everyday life, it’s easy to forget about email maintenance.

When was the last time you sat down and took a fresh look at the different aspects of your email marketing? How’s your subscriber segmentation, the health of your email list, and your subscriber forms?

Use the Summer season to get your email marketing back into a healthy shape.

1. Segment your readers

How can you get more personal with your readers? Analyze your list and group subscribers based on things like location, previous purchases, gender, age group, interests, and so on.

Marketers who use segmented campaigns note as much as a 760% increase in revenue, so this task is definitely worth getting sweaty for.

For example, when you know your reader’s location, you can send them flight offers for nearby airports or suggest weekend trips to neighboring cities.

Missing this information? Ask! Ulta Beauty does this in an engaging, interactive way in their monthly recap emails.

You can also gain customer insights by asking for feedback. This is easily done by embedding an email survey into your summer newsletter template. 

Now that things are a little quieter, you'll have the time to really go through the survey answers, listen to your readers and brainstorm ways to strengthen your brand.

2. Verify subscribers: Dust off your email list

Regularly cleaning your email list ensures that you’re protecting your sender reputation and improving your deliverability.

With a tool like MailerCheck, you simply need to upload your email list to verify subscribers. Once your emails are analyzed, you can import your cleaned email list and enjoy subscribers that are in top shape. This will save you money when sending your next summer campaign.

3. Refresh and optimize your landing pages and forms

Summer is a good time to check your stats and see what works best for your landing pages and which metrics you can improve. Maybe the wording can be more convincing or your images could use a touch-up. Small tweaks can make all the difference.

If you don’t believe me, ask copywriter Cole Schafer.

4. Send your newsletters at the right time

Have you experimented with the best time to send emails to your subscribers? Looking at our own data, we found that Thursday is the best day of the week to send, as this is the day emails get the most opens. We also found that most opens occur between 11 AM and 12 PM. You’ll want to test out different sending times to see what works best for your audience.

In MailerLite, you can also use the Smart sending feature, which allows you to send out your newsletter individually to each subscriber at the time they are more likely to open it.

Check out our guide on the best time to send emails to learn more.

5. Split test your emails

Carrying out A/B tests for your emails allows you to see which content, subject lines, CTAs, and design elements perform the best among a small selection of your audience. The winning email is then sent to the remainder of subscribers. Continuously split testing emails over time allows you to keep optimizing your emails based on real performance, so you can make informed decisions about what color buttons to use, whether to use emojis in your subject lines, and much more.

6. Use AI to help

AI is a wonderful thing, as long as we remember that it’s there to help us, not replace us! Use AI to help with content ideas, creating newsletter copy templates, or creative subject lines that you might not otherwise think of.

Use the summer to get your email marketing strategy in excellent shape and surprise readers with fresh content and eye-catching newsletter designs.

If you do, you won’t need to stress about your business suffering from summer fatigue. On the contrary, your readers will want to engage with your newsletters and celebrate summer with you.
