55 Memorial Day Email Subject Line Ideas

Table of Contents

Important Note: Never forget the reason behind Memorial Day. Memorial Day is meant to honor and mourn the heroes who have died for our country. Don’t be insensitive or forget the reason behind the holiday in your marketing campaigns.

Summer doesn’t officially begin until later in June, but Memorial Day — which happens on May 30th — feels like the beginning of summer. People meet at the lake, or at the cabin, or at the park (or whatever) for cookouts and beer fests. Whole families get sunburned for the first time that year. Festive, fun times (and aloe vera balm) reign supreme.

Where do all these happy people go after they’ve eaten themselves silly and played volleyball all afternoon? Why, they look for bargains in long weekend Memorial Day sales, that’s where. 

Online and offline, Memorial Day sales give businesses a big boost. Furniture and appliances retailers, for instance, see a 37% increase in revenue, while plant nursery sales go up by 45%. Plus, holiday sales are a great way to reengage with lost customers and create loyal buyers.

It makes total sense to cash in on the Memorial Day sale trend — and to create a Memorial Day email marketing campaign, too. To get the most bang for your buck, you’ll need a properly enticing subject line. Here’s our guide to Memorial Day email subject lines.

What’s in a Subject Line, Anyway?

Email subject lines can be surprisingly hard to come up with — even for marketers. Have you ever written an entire email only to find yourself totally stumped when it comes to the intro? You’re not alone.

It isn’t good enough to write “Memorial Day Sale Now On.” Nearly 50% of consumers skim over uninspiring subject lines in favor of entertaining intros. So, be entertaining, darn it!

But how? 

How to Write the Perfect Memorial Day Subject Line

Subject lines have to pique readers’ interests. Oh — and they can’t be too long, either. Here are 20 best practices to get you going:

  1. Keep it short. A lot of emails are read on mobile devices, so make sure your subject line doesn’t go over 60 characters.
  2. Make it urgent. You want recipients to buy your products today, not next week. Include a CTA like “Sale ends soon!” or “Buy now!” to create a sense of urgency.
  3. Get personal. If you can, personalize your subject line. “Rachel, it’s time to shop” almost feels like a command — so go with that.
  4. Stay away from “no reply” email addresses. Come on, let recipients reply to your emails. You’re not the Wizard of Oz.
  5. Capitalize on mystery. Phrases like “Read this right now!” or “You’ll never believe what we have in store…” make people curious. Curious people read marketing emails.
  6. Promote offers. This one seems obvious — but do promote your sale in your subject line. If you’re running a 50% off weekend, tell readers right off the bat.
  7. Tell a story. Got a short anecdote in mind? Turn it into a relatable subject line. People love relatable subject lines — just trust us on that one.
  8. Create segmented subject lines. College students probably won’t care about the reinforced knees on your khaki slacks — but gardeners aged between 40 and 60 might. 
  9. Don’t lie. Duh! Don’t say one thing and deliver another. If free shipping doesn’t start until the $25 mark, don’t imply that everyone gets free shipping, for example.
  10. Timing is everything. According to the good folks at Entrepreneur, emails sent on Tuesday mornings at 8:00 a.m. get the most responses. So, that’s your happy hour.
  11. Simplicity is key. Don’t use complex verbiage — instead, be concise and use easy-to-understand language.
  12. Begin with an action verb. Hold up, Rambo. Start your subject line with an action verb like “shop” or “subscribe” or “buy” or “discover.” Tell recipients what you want them to do.
  13. Include numbers. Tell readers how much they could save in percentage terms, or how many people have already signed up for your special pre-order offer. 
  14. Ask a question. Make it slightly accusing for best results — “Have you made this common skincare mistake?” for instance. Hey, it just works.
  15. Get punny. Don’t be scared to use a pun; consumers find that kinda fun. Punny subject lines tickle recipients’ funny bones and make them want to read more.
  16. Be trendy. Research trends within your industry to find out what’s on point, and create an email campaign accordingly.
  17. Choose your punctuation wisely. Moderation is everything, especially when it comes to exclamation and question marks. Pick one or the other — never both. 
  18. DON’T WRITE IN ALL CAPS. It’s just too in-your-face. Compelling subject lines are never shouty: they’re subtle, refined, soft-spoken marketing mavens. Like us.
  19. Use preview text. Okay, so this goes beyond your subject line — but add a tempting text teaser to increase your email open rate. 
  20. Test, test, test. Or at least test, test with an A/B split test. Send half your subscribers one subject line and send the remaining 50 percent your other subject line. Which one performs better? That’s your ideal intro right there.

One more thing: make recipients feel special. Tell them they’ve qualified for an exclusive offer and that you value them. They want to know that you think they’re swell. Which they totally are.
