Running low on inspiration for your summer campaigns? Don’t sweat it.

If you’re looking to spark engagement, grow your email list, or turn up those conversions, you’re in the right spot. These 15 summer marketing ideas are designed to bring the heat—and the sales.

Let’s jump in and make sure your store is ready to shine this season.

15 innovative summer marketing ideas for your online store

Each idea on our list is tied to a seasonal moment in June, July, or August. We’ve included a mix of actionable strategies, examples, and ready-to-use templates to help you get these ideas up and running fast.

June marketing ideas

1. Build your SMS list

If you’re not collecting SMS subscribers yet, why not start as part of your summer marketing plan? SMS marketing gives you a direct line to your audience—without the distractions of crowded inboxes or social feeds.

With open rates hitting 99%, SMS is perfect for flash sales, limited-time offers, and personalized messages. Plus, during the summer months when inboxes go quiet, SMS is an immediate way to connect with potential customers.

Use these summer-themed popups to capture phone numbers in style:

Want to give your list-building efforts an extra boost? Incorporate marketing strategies like using a countdown timer to create urgency and drive more signups.

2. Offer free shipping for Father’s Day

We celebrated moms in May—now it’s time to give dads some love.

A free shipping offer for Father’s Day can be the nudge summer shoppers need to hit “Buy Now.” Especially for gift-givers who might be shopping last-minute, free shipping removes a key barrier and makes your exclusive deals even more enticing. This is a perfect opportunity to encourage customers to take advantage of these offers.

Use a free shipping bar to make your offer impossible to miss. You can even customize it with a fun Father’s Day theme.

Make sure to promote it a few days ahead of the holiday—timing is everything for gift purchases.

3. Celebrate Pride month

Pride Month is more than a marketing moment—it’s an opportunity to stand for inclusivity and show what your brand believes in.

Whether you support a campaign, donate to LGBTQ+ organizations, or simply amplify diverse voices, your customers are watching. And yes, they notice when a brand actually walks the talk.

Make your store feel more inclusive with Pride-themed designs.

These popups can help:

Tip: Keep your messaging genuine. Your audience can tell when it’s performative vs. when it’s authentic.

4. Create a limited-edition summer product or bundle

Scarcity + seasonality = a marketing win.

Whether it’s a tropical-flavored product, a summer-themed bundle, or a special edition in bright, beachy colors, limited-time offers create urgency and give shoppers a reason to act now.

Here’s an example from Acqua Summer, who offered a limited edition bundle for the summer holidays:

And here’s another example from State, who offered a “Big Kids Travel Bundle”:

Pro tip: Name it something catchy like “Sunshine Set” or “Hot Days Essentials.” Make sure to highlight the limited quantity in your promos.

5. Host a summer challenge or giveaway

Challenges and giveaways are perfect for engagement, and they give people something fun to do.

Try creating a 7-day summer challenge (e.g., “7 Days of Summer Self-Care”), or run a giveaway where users can enter by sharing content, tagging friends, or signing up for your email list.

You can even promote your giveaways with an influencer to maximize your reach, like Credo Beauty did:

This is powerful, because it builds community and grows your audience. Remember, people love low-effort ways to win free stuff.

July marketing ideas

6. Add a countdown timer to boost urgency

There’s a reason countdown timers are a staple in conversion optimization: they tap into our fear of missing out.

Whether you’re running a July flash sale or promoting a limited-time bundle, a countdown timer adds just enough pressure to move the needle. Combine it with a strong offer—like 20% off or free shipping—and you’ve got a killer combo.

Add this popup to your homepage or product pages:

Keep the timer realistic—24 to 72 hours works best. Anything longer and it loses urgency.

7. Run a 4th of July promotion

The 4th of July is a natural sales opportunity, especially for American audiences. Patriotic themes, BBQ vibes, and long weekend shopping sprees—it’s all fair game.

Incorporating the 4th of July into your summer marketing ideas can significantly enhance your brand’s visibility and engagement.

Create a limited-time sale, offer bundles, or launch a “Red, White & New” collection. Whatever you do, market it in advance through email and popups to enhance your offer’s visibility.

These marketing strategies can help you capture the attention of summer shoppers and drive sales effectively.

Don’t forget to create a little buzz before the holiday. Brands like Happy Socks have nailed this by teasing their promos early and building anticipation.

Need a fast way to roll out your campaign? Use a themed popup to drive traffic to your July 4th deals:

8. Use an exit reminder

Discounts aren’t always necessary to convert. If you want to maintain your margins while still reducing cart abandonment, exit-intent popups are your friend.

They’re triggered when a user’s cursor movements indicate they’re about to leave, giving you one last shot to re-engage them.

Use exit-intent popups to remind shoppers about what’s in their cart, highlight fast shipping, or ask for feedback on why they’re leaving. You might be surprised at how effective a simple reminder can be.

It’s a smart, non-intrusive way to stay in the game—without handing out discounts like candy.

9. Partner with influencers for a summer collab

Summer is prime time for influencer content.

Partner with creators to feature your product in vacation vlogs, poolside hauls, or “what’s in my beach bag” posts. It’s authentic, visually appealing, and feels like a recommendation from a trusted friend.

These collaborations can effectively drive sales by reaching new audiences and enhancing your brand’s credibility.

Here’s an example from a partnership between Kendall Jenner and H&M.

Although Kendall Jenner is a major celebrity, you don’t need celebrity-level influencers. Micro-influencers with loyal niche followings often deliver better ROI.

August marketing ideas

10. Use full-screen popups

By August, most customers have tuned into “sale season.” This is your moment to stand out—and full-screen popups are a bold way to do it.

Use them to promote your end-of-season clearance, last-chance summer items, or an early back-to-school push. Because they take over the screen, full-screen popups are hard to ignore (in a good way).

Pro tip: Keep the message clear and the CTA strong. One offer, one goal. Don’t overcrowd the design.

11. Publish summer-themed content (blog + social)

Your audience is searching for summer tips, inspiration, and how-tos. So give it to them during August with engaging blog content that resonates with their needs.

Write blog posts that tie into your niche with a seasonal twist, and don’t forget to share them as social media posts for broader reach. Think along the lines of things like:

“How to Stay Cool While WFH”
“Top 5 Must-Have Accessories for Summer 2025”
“The Ultimate Guide to Summer Skincare for Busy Moms”

Check out GoodFair’s summer-themed blog article:

Remember to repurpose that content into Instagram Reels, carousels, and email newsletters.

12. Gamify your popups

If your usual “10% off” offer isn’t getting clicks, try gamification. Popups like lucky wheels or scratch cards bring a fun, interactive twist to your store—and make visitors more likely to engage, especially during summer promotions.

This isn’t just about entertainment. Gamification taps into reward psychology. People love the thrill of “winning” something, even if it’s the same discount you were offering anyway.

Just be sure to tie the reward to your business goals: email signups, SMS opt-ins, or immediate purchases.

13. Tie your brand to a summer cause

People want to support brands that stand for something, so it’s a good idea to align with a cause that resonates with the season and fits your brand.

Consider donating a percentage of summer sales to a cause tied to the season—like ocean conservation, outdoor youth programs, or heatwave relief. Then, share that mission through storytelling and customer updates to keep both new and existing customers informed.

This approach not only enhances your summer marketing mix but also builds an emotional connection between you and your audience. It shows that your brand is about more than just selling, which helps foster loyalty among customers.

14. Host a summer photo contest

This idea is perfect for August, when engagement starts dipping.

People love showing off their summer moments—whether it’s beachwear, backyard setups, or cute pets in sunglasses. Tap into this with a themed photo contest, which can effectively engage your customer base.

Check out this example from Voice of Health, who asks their audience to share tips for beating the heat.

Ask customers to share pictures using your product for a chance to win a prize. Highlight entries in emails or popups to boost visibility and build trust.

15. Back-to-school campaigns

Back-to-school isn’t just about notebooks and backpacks—it’s a huge retail moment. According to NRF, over 50% of parents start shopping in July, and the momentum continues into August.

If your products fit the season—think fashion, accessories, tech, home decor—start promoting them early to reach potential customers. Even if you’re not in a typical school niche, you can still position your offers around “fresh starts” or productivity.

Use these popup templates to promote your back-to-school deals:

FAQ

Do these ideas work for non-seasonal products?

Yes, and they often work even better. The key is to align your messaging with the season, even if your product isn’t summer-specific. By incorporating summer marketing ideas, you can enhance relevance and timing to capture the essence of the season.

What’s the best channel for seasonal marketing?

Ideally, a mix of on-site popups, email, SMS and social media works best. Popups capture attention on your site, while email and SMS drive external traffic back in.

Should I promote these summer campaigns on social media, too?

Definitely. Social media is the perfect place to build hype around your summer marketing ideas and boost engagement. Use Instagram Stories, TikTok videos, or carousel posts to tease promotions, share user-generated content, and drive traffic back to your store.

Pairing your popups with social campaigns creates a consistent customer journey and amplifies your reach.

Recap

Summer might be short, but it’s packed with high-impact opportunities. Whether you’re running a flash sale, building your list, or launching a campaign for Pride or back-to-school—you’ve got options.

So pick your favorite summer marketing ideas, test different strategies, and make this your most profitable summer yet.
