Summer messaging to customers: tips & tricks that actually work

Why summer changes everything in customer messaging

Summer isn’t just a season – it’s a behavioral shift. Open rates drop. Attention spans shrink. Your customers are checking phones poolside, boarding gates, and beach bars. They’re distracted, sun-dazed, and ruthlessly selective about what deserves their attention.

For brands this creates a paradox: summer is the peak commercial season – travel, retail, F&B, entertainment, hospitality – yet it’s also the hardest time to land a message that actually converts.

Summer messaging data tells a consistent story – and it’s full of actionable lessons. Here’s what works, what doesn’t, and how to make your summer communication campaigns genuinely effective.

Rethink your timing – completely

Forget your standard “Tuesday 10am” send schedule. Summer audiences operate on vacation logic.

What the data shows:

• Engagement peaks shift to early mornings (7–9am) and late evenings (8–10pm) – the “bookends” around beach and leisure time
• Midday sends (11am–3pm) see the steepest drop in CTR during summer months
• Weekend engagement surges, particularly for leisure, travel, and hospitality verticals

The fix: Audit your send-time optimization settings by segment. Business customers still behave like business customers even in July. But B2C audiences need a fundamentally different cadence. Use behavioral triggers rather than fixed schedules wherever possible. A message sent 10 minutes after a user opens your app beats any static send-time prediction.

Keep summer messaging short. Then cut it in half again.

Your customers are reading messages in sunlight – literally – often with one eye on their kids and a cocktail in the other hand.

SMS best practice: Stay under 100 characters whenever possible. If your SMS exceeds you’ve already lost a significant chunk of your audience.

For longer-form channels (WhatsApp, Viber): lead with the value proposition in the first line. If the first sentence doesn’t hook, the rest is invisible.

“Get 30% off your next stay – this weekend only. Book now →”

That’s a complete summer message. CTA included. No brand manifesto required.

Go multichannel – but with purpose

Running the same message on SMS, WhatsApp, Viber, and email simultaneously isn’t a multichannel strategy, it’s spam with extra steps.

Smart multichannel logic for summer:

• SMS  – Urgent, time-sensitive offers; OTP; flash sales 
• WhatsApp – Rich media promotions; two-way customer service 
• Viber – Visual campaigns; loyalty rewards; event invitations 
• RCS – Interactive product showcases where supported 

The key principle: let customer behavior determine the channel, not your campaign calendar. 

ImLink cascade messaging addresses two major challenges at once. It starts by sending messages through the most cost-effective channels, and only escalates to more expensive options if delivery fails. This ensures reliable message delivery while reducing costs by 30-70%, solving both the issues of high messaging expenses and delivery failures.  

Embrace summer triggers and contextual personalization

Generic “Summer Sale!” blasts are white noise. Contextual messages that acknowledge where a customer is – mentally, physically, or in their customer journey, cut through.

High-performing summer trigger examples:

• Weather-based triggers: “It’s 34°C in your city – cool down with 20% off our delivery menu today.”
• Location-based triggers: Messages activated when a user enters a geofenced zone near your store or venue
• Behavioral triggers: Abandoned cart reminders timed to evening hours; re-engagement flows for users who’ve gone quiet since June
• Anniversary/milestone triggers: “You’ve been with us for a year – here’s a summer gift.”

Personalization in summer shouldn’t feel like data surveillance. It should feel like good timing. The difference is subtlety and relevance.

Vacation mode customers are still customers

Here’s a mistake many brands make: they pause outreach to customers who haven’t engaged in two to three weeks, assuming they’re “on vacation.” Wrong approach.

Vacation-mode customers are often in a high-spending mindset. They’re booking, ordering, exploring, and treating themselves. What they’re not doing is tolerating irrelevant communication.

Strategy: Create a dedicated “summer dormancy” segment. Rather than pausing contact entirely, shift to:

• Lower frequency (one message per week maximum)
• Higher-value offers only – no informational fluff
• Channels with higher ambient engagement (push notifications, WhatsApp)

The goal is to stay top-of-mind without becoming the reason someone hits “unsubscribe” from their sun lounger.

Optimize for thumb-stopping visuals on rich channels

Summer is visual. On channels like Viber, WhatsApp, and RCS, lean into this aggressively.

What works:

• Bright, high-contrast imagery (summer palettes: coral, turquoise, citrus)
• Short video clips under 15 seconds –product demos, destination showcases, behind-the-scenes
• GIFs for lightweight animation without heavy file loads
• Countdown timers embedded in rich messages for flash deals

What doesn’t work:

• Stock photos that look like every other summer campaign
• Cluttered layouts with three CTAs competing for attention
• Dark or moody creative – wrong season, wrong mood

ImLink RCS and WhatsApp Business API integrations allow brands to send carousel messages, quick-reply buttons, and embedded booking flows – turning a single message into a complete conversion experience.

Build in a post summer messaging reactivation plan now

The smartest summer campaigns aren’t just thinking about July. They’re building the foundation for September.

Every summer interaction is a data point:

• Who engaged with which offer?
• Which channel converted best by segment?
• Who opted out, and why?
• Which customers showed high intent but didn’t convert?

Action: Tag and segment summer behaviors as they happen. By late August, you’ll have a precision-targeted reactivation list ready for September campaigns – traditionally one of the highest-converting months of the year as customers shift back into routine and spending habits normalize.

Final thought: summer rewards the relevant

The brands that win in summer messaging aren’t the ones with the biggest budgets or the most aggressive send frequencies. They’re the ones that show up at the right moment, on the right channel, with a message worth reading.

Summer is a test of relevance. Pass it – and you head into Q4 with a warm, engaged audience. Fail it – and you spend September recovering from opt-outs and damaged sender scores.
