Top 5 best performing Memorial Day subject lines (based on Omnisend Research)

We searched through more than 9,000 of our bigger brands’ Memorial Day email campaigns to find out what the best, highest-performing subject lines are.

Because we’re dealing with subject lines, we’re focusing mainly on which subject lines had the highest open and click rates.

#1 Memorial Day subject line: “30% Off Memorial Day Sale

  • Open rate: 44% | Click rate: 16%

#2 Memorial Day subject line: “Memorial Day savings – save 25% off EVERYTHING!!

  • Open rate: 38% | Click rate: 18%

#3 Memorial Day subject line: “HAPPY MEMORIAL DAY WEEKEND!

  • Open rate: 37% | Click rate: 17%

#4 Memorial Day subject line: “Memorial Day Secrets

  • Open rate: 34% | Click rate: 7%

#5 Memorial Day subject line: “MEMORIAL DAY WEEKEND PROMO: Memorialday17

  • Open rate: 33% | Click rate: 4%

With Memorial Day subject lines, we see that some merchants are not willing to put a discount percentage or other obvious benefits, even though they actually worked.

Looking at the top two subject lines, a clear discount was definitely an important factor that increased the open rate.

Also, an interesting tactic was chosen in the #5 subject line. Even if the email is not opened, there’s a chance that a recipient will use the discount code in the subject line.

When you’re creating Memorial Day subject lines, don’t hesitate to try out many different things and see what works.

Not sure which subject line to pick? How about two at the same time?

Omnisend allows online marketers to send emails with A/B testing with two different subject lines. A/B testing allows you to send out two subject lines or two different sender’s names to a small percentage of your recipients so you can see which one worked best.

The one with the highest open rate (or click rate) then gets sent automatically to the rest of your recipients.
