Sizzlin’ hot summer newsletter ideas for 2021

While summer can be a slow time for business with lower newsletter engagement, it's definitely not the time to stress. 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 summer’ize your newsletters.

With the hustle and bustle of everyday life, you easily 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 season to get your email marketing back into its healthy shape.

1. Segment: Group 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! KLM does this in an engaging, interactive way in their welcome email.

You can also gain customer insights by asking for feedback. This is easily done by embedding a 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

Cleaning your email regularly 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. Optimize: Refresh your landing pages and forms

Summer is a good time to check your stats and see what numbers 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.

Your business might suffer from summer slow motion, but don’t give up on your email marketing efforts. Instead, take inspiration from these engaging summer newsletter ideas.

Downloadable lists: Ready, prep, go!

Create a summer list. What to pack for a solo trip to Asia, how to get in shape in 31 days, 33 must-read books to finish this summer—you can create a list about practically anything.
