Sun’s out, open rates up! Summer’s both busy and distracting for subscribers. Cut through the noise and grab attention with these proven tips for refreshingly compelling summer email subjects.
Why Summer Emails Need Catchy Subject Lines
Summer might seem like a sleepy season, with people lounging at the beach or napping in hammocks. But for email marketers, it’s anything but! Summertime inboxes get more crowded than ever.
To stand out, you need attention-grabbing subject lines that break through the noise. Here are three reasons why catchy summer email subjects are essential:
Getting Attention in Crowded Inboxes
Let’s face it – everyone wants a piece of your subscriber’s inbox. From daily deals to vacation reminders, summer sees a surge of promotional emails. With so many messages flooding inboxes, you need to catch your audience’s eye fast.
Creative subject lines pique curiosity and compel readers to open. For instance, “30 beach reads under $10” sparks interest better than a generic line like “Summer eBook Sale.”
Subjects with urgency also work. “24 hours left for 50% off!” conveys a fleeting chance to grab deals. stat that time-limited subject lines have a 70% higher open rate.
Finally, leveraging seasonality reminds people of summer activities they love. “Refreshing ranch water cocktail recipes” evokes carefree vibes better than non-seasonal topics.
Overcoming the Vacation Mindset of Recipients
During summer, people are often in vacation mode. Their minds drift to tropical getaways, not emails. That’s why an engaging subject line is crucial for breaking through daydreams of palm trees and beach bars.
One effective technique is tapping into FOMO – the fear of missing out. “Final call for summer essentials!” piques curiosity about limited-time offers.
Another approach is using humor or puns like “A sale so nice, you gotta buy it thrice.” Silly wordplay offers a fun distraction from the heat.
References to summer fun also work. A camping retailer could try “S’mores, snores, and outdoor deals!” Linking discounts to campfire favorites catches attention.
Standing Out with Seasonal Relevance
Email overload means readers only fully process emails that seem worthwhile. So seasonal relevance in the subject boosts that perception of value.
For example, “Red, white and BOOM! 4th of July sale” ties deals to a major summer holiday. Its specificity promises useful, time-limited content.
Meanwhile, a general line like “Summer deals at Brand.com” seems vague and forgettable. Without seasonal details, it risks getting lost in the fray.
Brands like J.Crew lean into seasonality with subjects like “Sunny weekends ahead! Extra 50% off sale styles.” The summery phrasing makes their promotion shine.
Even businesses less tied to summer can benefit from seasonal nuances. A bookkeeper could try “Organize summer receipts with 25% off QuickBooks.” Tailoring subject lines to the season makes them more clickable.
With a bit of creativity, any business can take advantage of summer themes and stand out in crowded inboxes. The right subject line invites readers to engage instead of hitting delete. So take time to brainstorm seasonal hooks and irresistible wording to captivate your audience. Summer’s fleeting weeks will fly by before you know it!
Summer Email Subject Line Dos and Don’ts
Crafting compelling subject lines is both art and science. While creativity counts, you also need to know key best practices that engage recipients. Follow these summer email subject line dos and don’ts, and you’ll be on your way to higher open and click-through rates.
Keep it Short and Scannable
Inboxes are crowded, and attention spans are short. That’s why concise, scannable subject lines work best for summer campaigns.
Do:
- Limit subject length to 30-50 characters
- Front-load key information
- Use fragmented phrases instead of full sentences
For example, “Sunny deals end today!” packs a punch at just 16 characters. The time limit creates urgency while promising summer appeal.
Don’t:
- Ramble on with lengthy subjects
- Bury your hook under wordy introductions
- Use convoluted language
Avoid subjects like “We’re overstocked for summer and passing the beach-ready savings to you!” At 51 characters, it’s easy to lose the lead. The core message gets drowned out.
Use Seasonal Keywords and Emotional Triggers
Summer-themed keywords catch the eye, especially when combined with emotional triggers related to the season.
Do:
- Use summery words like sun, heat, August, and phrases like beach vacation or summer road trip.
- Tap into emotional triggers like adventure, relaxation, freedom or nostalgia.
- Leverage seasonal events and holidays like Fourth of July, Memorial Day, back to school.
For example, “Your summer road trip essentials are here” combines seasonal keywords with emotional concepts. Meanwhile, “Red, white and boom! Fourth of July sale” taps into a specific holiday.
Don’t:
- Stick to dry, generic phrases that could apply to any season.
- Neglect including any seasonal details or emotional hooks.
“30% off everything” lacks creativity and summer specificity. Without an element of seasonality, it’s likely to blend into the inbox noise.
Avoid Spammy Words That May Get Filtered
Some words are red flags for spam filters, especially if overused. Stay away from risky language to keep your email out of the promotions tab or spam folder.
Do:
- Review your subject lines for frequently filtered words like “free,” “sale,” “discount,” “money,” etc.
- Use them sparingly and avoid grouping them together.
Don’t:
- Lean too heavily on problematic keywords most associated with spam.
- Downplay your subject line’s value proposition just to avoid filters.
“Free money now!” would likely get snagged immediately. But a subject reading “An exclusive summer gift inside” still conveys added value without the warnings signs.
Personalize When Possible
The recipient’s name adds a special touch, as do details about their purchase history or interests. Segmenting your list allows personalization at scale.
Do:
- Address people directly by their first name when possible.
- Reference past purchases or browsed items.
- Tailor subject lines by buyer persona or purchase history.
For example, “Jessica, don’t miss this one-day flash sale!” feels more 1:1 than a generic subject. Just take care not to get too familiar.
Don’t:
- Use overly casual language like “Hey girl!” which may seem unprofessional.
- Make assumptions about preferences based on stereotypes. Keep personal details specific to the individual.
Experiment with Emojis in Moderation
A summer emoji or two can infuse seasonal cheer into subject lines. But use them strategically so they don’t appear unprofessional.
Do:
- Limit emojis to 1-2 per subject maximum.
- Choose relevant seasonal emojis like ☀️, 🏖, ⛱, 🍦.
- Test emoji placement to see if front, middle or end drives more clicks.
For example, “It’s sundress season! ☀️ 25% off all dresses” uses a sun emoji to accentuate summer appeal.
Don’t:
- Overload subjects with hard-to-decode emoji strings.
- Use emojis that seem childish or unaligned with your brand voice.
- Neglect testing to see if emojis lift or depress your open rates.
Summer Subject Line Ideas for Promotions
Summer promotions let you clear old inventory and generate revenue during slower months. Catch more opens for your summer sales and deals with these seasonal subject line examples:
- 30% off for a limited time only!
- Flash sale this weekend: 50% off summer styles
- Final call! Our summer sale ends tomorrow
Urgency and scarcity prompts get attention fast. Phrases like “limited time only” and “ends tomorrow” convey exclusivity. Stats show time-limited offers have a 70% higher open rate.
Deep discounts also get noticed. “50% off summer styles” promises big savings off in-season merchandise. Make the discount specific to summer items for maximum appeal.
And words like “flash sale” and “final call” build excitement by suggesting a fleeting chance. These high-momentum subjects inspire action.
Subjects for New Summer Collection
Announcing new seasonal arrivals in your subject line can also attract interest from subscribers. Here are engaging ways to highlight fresh summer products:
- Sneak peek: Our summer collection has arrived!
- The summer trends you need are finally here
- Your new favorite summer styles inside!
Lead with “sneak peek” or “new arrival” to convey exclusivity, as if unveiling products before the public launch. This makes subscribers feel like VIPs getting early access.
Spotlight the summer angle upfront for relevance. Phrases like “summer collection” and “summer trends” promise seasonal appeal.
End with specific teasers like “new favorite summer styles” to create anticipation. Give just enough detail to pique curiosity without giving away too much.
End of Season Summer Email Subjects
The end of summer is a prime time to convert final sales as shoppers realize summer is coming to a close. Urgency is important in these closeout subject lines:
- Last chance for 50% off summer deals
- Summer’s almost over – shop these final markdowns
- Hurry! Final days of our summer sale
Reminding shoppers of summer’s imminent end prompts purchases while inventory and sizes remain available. Phrases like “last chance” and “final days” impart scarcity.
Big percentage discounts also help, signalling deep savings on closing summer products. Make the seasonal angle clear with wording like “summer deals” and “summer sale.”
And urgent cues such as “almost over” and “hurry” add pressure to buy before the clock runs out on summer deals. This fear of missing out (FOMO) strategy wins last-minute conversions.
Subject Line Ideas for Summer Holidays and Events
Tying your subject line to major summer happenings makes your content more relevant for the moment. Tap into these upcoming summer holidays and events:
Fourth of July Subject Lines
The July 4th holiday presents patriotic summer savings opportunities. Some 4th of July email subject line ideas include:
- Let freedom ring! 30% off red, white & blue styles
- Spark savings this Fourth! 25% off everything
- Independence Day deals are here!
Use holiday shorthand like “Fourth of July” or just “Fourth” to reference the occasion. Merging patriotic colors and savings conveys summer spirit.
Keywords like freedom, spark, and independence link discounts to the holiday’s values. This helps avoid overly commercialized language around July 4th.
And make sure to highlight the deal or percent-off clearly. Saving money and celebrating freedom go hand-in-hand!
Back to School Subject Lines
Late summer is back to school season, making it smart to theme emails around the new school year:
- Get ready for school with 20% off supplies
- New year, new gear! 30% off backpacks & lunchboxes
- School’s out! Time for back to school deals
Mentions of “school,” “new year,” and “back to school” put the seasonal concept front and center. This taps into parents’ need to purchase supplies.
Spotlight school-related categories like backpacks, lunchboxes, dorm furnishings, and laptops. Listing specifics piques interest from deal seekers.
And timing is key. Running back to school offers right as summer breaks ends accommodates last-minute shoppers.
Summer Subject Line A/B Testing Tips
Take the guesswork out of summer subject line creation by A/B testing different variables. Try these experiments:
Test Call-to-Action Phrases
Does urgency like “24 hrs only!” outperform exclusivity such as “VIPs only” for your audience? Try subject lines that use:
- Limited-time words: last chance, ends soon, flash sale
- Exclusive words: VIP, insider, reserved
- Discount words: extra 30% off, promo code inside
See if any phrasing consistently lifts open and click-through rates higher over a two-week period when compared to a control subject.
Try Different Seasonal Keywords
Does “summer” get more traction than “July” or other seasonal words? Test a variety of keywords head-to-head:
- General summer words: summer, sunny, heat wave
- Month-specific words: July, August, fall
- Event words: July 4, Memorial Day, back to school
You may uncover surprising results, like subscribers responding better to “fall” than “summer” savings toward August.
Experiment with Punctuation and Symbols
Icons, punctuation, brackets, and symbols can all impact email open rates. Test the effects of:
- Emojis: ☀️😎🏖️🌴 vs no emoji
- Brackets: [Limited supply!] vs no brackets
- Symbols: 50% off vs 50% off
- Caps: DON’T MISS OUT vs Don’t Miss Out
Track open rate lift for these styling variables. However, be wary of overusing gimmicks if they don’t align with your brand voice.

Subject Line Ideas for Summer Holidays and Events
Major summer holidays present fun opportunities for seasonal savings. Tie your subject line to upcoming summer celebrations and events to create relevance.
Fourth of July Subject Lines

Some creative ways to highlight Fourth of July savings in your subject line:
- Let freedom ring! 30% off red, white & blue styles
- Spark savings this Fourth! 25% off everything
- Independence Day deals are here!
The first subject line ties discounts to a patriotic color scheme, calling out savings on red, white and blue products. This builds seasonal excitement while showcasing deals.

Make sure to call out the percent-off or specific deal clearly too. Saving money and celebrating freedom go hand in hand!
Other July 4th subject line tips:

Some back to school subject line examples:
- Get ready for school with 20% off supplies
- New year, new gear! 30% off backpacks & lunchboxes
- School’s out! Time for back to school deals
Mentions of “school,” “new year,” or “back to school” instantly give the subject seasonal relevance. Calling out related categories like backpacks and supplies appeals directly to parents’ needs.
Timing these subject lines toward summer’s end targets shoppers before the school rush. Highlight school-themed discounts to attract deal-seeking parents.
Other back to school subject tips:
- List specific supplies like notebooks, pencils, binders to catch parents’ eyes
- Use keywords like new year, first day, back to school, new clothes, school supply
- Tie into major sales like Black Friday in July or end of season clearance
- Add urgency like “sale ends Sunday!” to prompt purchases
Summer’s last stretch is prime back to school season. Maximize this sales opportunity by aligning subjects with parents’ late summer purchasing needs.
Summer Subject Line A/B Testing Tips
Crafting winning summer email subjects doesn’t have to be a guessing game. A/B testing allows you to experiment with different variables and pinpoint exactly what makes recipients open.
Here are some key elements to test for higher summer open rates:
Test Call-to-Action Phrases
Your call-to-action often makes or breaks subject click-appeal. Test urgency versus exclusivity wording:
- Urgent words: 24hrs only!, today only, ends soon, act now
- Exclusive words: VIP sale, insider deals, reserved for you
For example, send one campaign with “VIP Members Only – Summer Blowout Sale!” and another using “Today Only – Summer Blowout Sale!” Monitor opens over a two-week period to see which nets higher rates.
You can also test action words like “claim” or “explore” versus more passive phrases like “save on” or “discover.”
And don’t forget discounts! Test subjects with “extra 50% off” compared to “free shipping.” Track which type of deal resonates more.
Try Different Seasonal Keywords
Certain summer words, months and associations may outperform others with your audience. Test a variety to identify terms that pop.
Some options:
- General summer words: summer, sunny, heatwave
- Month-specific: July savings, August deals
- Event-related: Memorial Day, July 4, Labor Day
You might find subscribers surprisingly responsive to “fall” or back to school themes starting mid-August. Don’t assume – let data guide keyword choices.
Experiment with Formatting
Icons, symbols, and stylistic tweaks can impact opens. Test effects of:
- Emojis: ☀️🌴🏖️ vs no emoji
- Brackets: [Limited supply] vs no brackets
- Symbols: 50% off vs 50% off
- ALL CAPS: HURRY vs Hurry
- Exclamation points: Deal! vs Deal
For example, compare “Summer sale!” against “Summer sale” to see if the exclamation lift open rates.
But use gimmicks judiciously – less is more. Overdoing effects may hurt credibility for certain brands.
Tips for Summer Subject Line A/B Testing
To accurately assess what copy and styling wins, follow these guidelines:
– Isolate the variable being tested so that subject lines are identical except for the single element being changed
– Split test groups evenly so data is based on segments of equal size and traits
– Test for a consistent time period like 2 weeks to account for normal waves
– Avoid other email variables during the test window that may skew data
– Compare metrics like open and click-through rates using adequate sample sizes (100+ sends)
– Calculate lift to determine statistical significance
– Focus on big differences since subtle variances under 5% may be noise
Well-designed A/B testing takes the guesswork out of optimizing summer campaign performance. You’ll quickly learn exactly which seasonal styles, offers, and phrasing pops for your subscribers.

Tools to Improve Summer Email Deliverability
Summer’s crowded inboxes make it critical to optimize deliverability. Use these tools to help email reach the inbox:
Warm Up New Subject Lines Before Sending
Instead of sending a brand new subject to your full list, first seed it to a small test segment. This helps ESPs gauge engagement and spam risk before larger sends.
Try warming up each new subject line with at least 100 recipients for 1-2 weeks before rolling out more broadly. Monitor spam complaints and open rates. Subjects that underperform with the test group can be refined or replaced to prevent issues at scale.
Warmup services like Pepipost](https://www.pepipost.com/features/email-warmup/) and [Mailgun Warmup can automate and simplify the seeding process.
Analyze Email Analytics to Identify High-Performing Subjects
Review data from past summer campaigns to uncover your most effective subject lines. Identify words, offers, and styles that resonated. Then replicate what succeeds.
Analytics to examine:
- Open rates: Which subjects have the highest/lowest open rates?
- Click-through rates: Which subject lines lead to the most clicks after opening?
- Conversion rates: Which subjects drove the most desired actions like purchases?
- Unsubscribe and spam rates: Are certain subjects hurting engagement?
Isolate your seasonal star subject lines based on performance then recreate those wins. Continually refine through new A/B testing too.
Ensure Mobile Optimization for Subject Lines
Since over half of emails are opened on mobile, preview how subject lines display on phones before sending campaigns.
Some mobile optimization tips:
- Use 30-50 character subject lines to prevent truncating
- Avoid cramming long names like “JohnSmithFurnishings” which cut off
- Eliminate extra spaces and repetitive words
- Left-align lines and topics
- Make key info prominent at the start
- Use 1-2 emojis max for clarity
- Test CTAs and season keywords on mobile screens
Scannability is essential for tiny mobile screens. Verify nothing crucial gets clipped or buried on phones to maximize deliverability.
Subject Line Best Practices For Any Season
Beyond summer-specific techniques, certain universal best practices create winning subject lines year-round.
Limit Subject Length for Mobile Devices
Keep subjects under 50 characters so they don’t truncate awkwardly or get cut off on small screens. 30-40 characters is optimal.
Speak to Customer Needs and Interests
Ensure topics and keywords align with your audience’s values, preferences and concerns. Subject relevance boosts open likelihoods.
Ensure Clarity and Accuracy
Avoid ambiguous claims or hyperbole that may mislead. Keep subjects clear, concise and honest.
Use Personalization When Possible
Add first names, past purchase details, or custom segment attributes if applicable to boost opens. But stay away from over-familiarity.
Additional Tips:
- Prioritize scannability with fragmented phrases vs. lengthy sentences
- Front-load the core value proposition within first 30 characters
- Leverage the preview text to provide additional context
- Limit punctuation, symbols, gimmicks; less is more
- Avoid spam filter keywords like “free,” “sale,” “money” in excess
