For retail marketers, summer is a season with genuine commercial momentum: customers shopping for vacations, updating their wardrobes for weddings and festivals, buying gifts for Father's Day, or bracing for back-to-school. 

However, as consumers spend more time outdoors and offline, many brands find that open rates, click-through rates, and conversion rates soften. And for brands whose products aren’t inherently ‘summery’, the challenge is even more significant.

As we gear up for the sunnier months ahead, we compiled our top tips for thriving through the summer season, from campaign inspiration and creative ideas to personalization best practice and Black Friday prep.

Tap into the big cultural moments

Tying your campaigns to big cultural moments is a reliable way to add relevance to your sends, especially for brands whose products don't naturally map onto the season.

Here are the occasions worth building into your plan.

Big summer days

Key dates:

• Memorial Day — May 25th, US
• Pride Month — June, international
• Father's Day — June 15th, US and UK
• 4th of July — July 4th, US
• Summer Bank Holiday — August 25th, UK

Ways to tie in:

• Themed product edits or curated gift guides work well for Father's Day and the 4th of July across apparel, homeware, food and drink, and outdoor categories
• Pride Month rewards a thoughtful approach: campaigns that connect to your actual brand values, community, and any organizations you support will always land better than purely cosmetic efforts
• The Summer Bank Holiday is a natural window for end-of-season clearance or a late-summer push

Patch Plants created a natural link between Father’s Day and their product range, highlighting giftable products with male names and copy with subtle references to the occasion.

Music festivals

Key dates:

• Coachella — April, US
• Primavera Sound — 4th–6th June, Spain
• Ultra Europe — 10th–12th July 2026, Croatia
• And many, many others

Ways to tie in:

• Festival-inspired product edits and editorial-style campaigns work well for fashion, beauty, and outdoor lifestyle brands
• Food and drink and travel brands have a natural angle in the experience and escapism of festival culture
• The occasion lends itself to brand-building content as much as direct commercial messaging

EGO targeted festival shoppers with this broadcast send, segmenting by customers that had viewed but not purchased from the category, and those that had previously bought from the category.

Sporting events

Key dates:

• FIFA Club World Cup — June 14th to July 13th, US
• Wimbledon — June 23th to July 6th, UK
• Tour de France — July 5th to July 27th, France
• US Open — August 25th to September 7th, US

Ways to tie in:

• Wimbledon and the Tour de France carry strong associations across lifestyle, apparel, and food and drink categories
• The FIFA Club World Cup is the standout new addition this year: a genuinely global audience with strong crossover appeal for sportswear, apparel, and lifestyle brands
• Even tangential tie-ins (viewing occasion food and drink, sports-adjacent fashion) can perform well when the messaging is specific rather than generic

Back-to-school

Key dates:

• July onward in most US states
• August peak in the UK

Ways to tie in:

• The most obvious categories are clothing, footwear, stationery, sports equipment, and tech, but the window is wider than it first appears
• Working professionals often experience a similar seasonal reset. Thinking about back-to-school as a broader “new season, fresh start” occasion, rather than a purely family-focused one, tends to bring more of your customer base into scope

Give your automation emails a summer boost

Your core automation flows (welcome series, abandoned cart, post-purchase, win-back) are an extremely valuable part of your CRM strategy year-round, so it’s worth keeping the creative and copy fresh to ensure they stay relevant to the current seasonal moment.

A few updates worth making:

• Swap out hero imagery for something seasonally relevant
• Update copy to reflect the time of year, even in small ways: a reference to the season in a subject line, a line of preview text, etc.
• Consider new automation variants. For example, with summer being peak wedding season, you might consider a bridal variant of some of your key automations (welcome, post-purchase, abandoned cart) if your brand is aligned with bridal or wedding gifting.

ME+EM updated their welcome flow with hero imagery from their SS26 campaign.

Lean in to smarter, seasonal segmentation

Seasonal relevance doesn’t stop at your template design. Use segmentation to reach customers with the products they’re interested in now, not the depths of winter.

Ometria's AI-powered product affinity segmentation allows brands to build audiences of customers most likely to engage with specific product categories, and use that to add a smart layer of personalization to their sends.

As summer approaches, our clients are shifting their category logic accordingly: moving away from outerwear and knitwear and building audiences around summer-relevant lines. One womenswear retailer has been segmenting by affinity toward specific dress lengths (mini, midi, maxi) with promising early results.

Get strategic about your sale

Sales aren't just a way to clear end-of-season stock. To see greater returns from a period of markdowns, it's worth thinking about how it can serve your broader CRM goals too.

• Prioritize lead acquisition before the sale opens. If volume is a priority, a pre-sale acquisition campaign (for example, through paid social) gives you a larger, warmer audience ready to hear from you on day one. 
• Turn your sale into a re-engagement opportunity. If reactivating lapsed shoppers is the focus, particularly with Q4 on the horizon, measure sale success against how many customers you bring back. Pay particular attention to the post-purchase journey, ensuring reactivated customers remain warm into Q4.
• Treat your VIPs. Your highest-value customers deserve more than a forwarded version of your general sale email. Early access, a higher discount tier, or a gift with purchase reserved for your top tier are all ways to reinforce that relationship rather than erode it.

Catch them at the perfect time 

With customer attention harder to capture, a well timed message can be the perfect way to cut through.

Recent data suggests that interest in summer clothing starts building as early as February, accelerates through spring, and peaks in May and June. For brands where swimwear, vacation-wear, or travel-ready categories are commercially significant, that buying window is worth planning around carefully.

Ometria's AI-powered predicted date of next order gives brands a way to act on that timing at a customer level, rather than broadcasting to everyone at once. 

What does this look like in practice? One of our clients in the swimwear and beachwear space has been using it to build a cohort of shoppers whose predicted next purchase falls before ‘peak summer’, and targeting that audience with messaging built around pre-vacation shopping.

Leverage your stores

Physical stores are an underused data asset during the summer months, particularly for brands with destination locations or a strong regional footprint.

In-store events and pop-ups are an obvious place to start, but the value is in how you connect them to your customer data. Steve Madden ran a series of in-store events in summer 2025 and used Ometria's geo-targeting to build segments of customers within a defined radius of each store location, allowing them to target those most likely to attend.

A different angle comes from thinking about where your customers shop, not just when. One of our clients in the luxury space maintains a "Travellers" segment built around customers who have purchased at one of their airport or resort locations, allowing them to tailor messaging to this group’s unique traits and mindset. 

Steve Madden used geo-targeting for their summer in-store events, ensuring the most locally relevant customers received the comms.
