Memorial Day barbecues have been lit, and summer is officially upon us. As temperatures rise and people are spending more time grilling and soaking up the sun outdoors, how can you capture their attention with your email subject lines?

While there’s a lot on your seasonal to-do list – rooftop parties, trips to the beach and picnics in the park among them – your email subject lines could use a little summer lovin’ too. To provide inspiration, we’ve put together a list of 50 sunshiny and seasonal subject lines. Plus, we’ve got three bonus tips to help you create your own fun-in-the-sun subject lines.

Three tips to help you add a dose of sunshine to your next subject line

1. Draw attention with summer words and phrases

How are you celebrating summer at your business? Let it shine through in your email subject lines, but remember to keep it short and attention-grabbing. Use common summer words and references like these suggestions:

  • Celebrate summer with a heat wave sale
  • Provide solutions to summer problems like mosquitoes and sunburn
  • Make a list of lawn maintenance tips or suggestions for a fun family grill out
  • Talk about summer must-haves, summer safety or summer places
  • Use summer words and phrases like fun in the sun, beat the heat, high temps and dog days of summer

Where appropriate you can also consider using seasonal emojis – but be sure to test their performance and deliverability!

2. Promote a summer sale

An easy way to tie your email to summer is to promote a seasonal sale. Craft an exciting line that encourages customers to open the email immediately. Tell them exactly what they’ll see when they open it. For example, “Don’t miss out on the big summer sale — Promo codes inside,” or “Save 40% on all summer merchandise.” You could also tie your sale to a summer holiday, from Memorial Day to the 4th of July to Labor Day.

3. Create a calendar of local events

People will look forward to your emails if they know they’re getting more than just an in-your-face promotion. Everyone wants to know about the hottest and most popular summer events, so add a calendar of local events to your emails. Give your customers something to get excited about, from local fireworks to the best farmers markets around town.

Don’t let all that hard work on your email marketing campaigns go to waste. Use these tips to keep your open rates up and your business growing all summer long. check out: 40 sun-sational subject lines for summer
