170+ best Mother’s Day subject line ideas

Everyone loves their Momma. This is a big holiday where grateful children, husbands, brothers and sisters show their appreciation for the mothers in their lives. Mother’s Day in the United States is on May 14, 2023.

Therefore, it’s important that you use the best-performing (and most creative) Mother’s Day subject lines to make sure you’re helping your customers appreciate the mothers in their lives in the best way.

FYI: don’t forget to read up on how to use proven techniques to craft the best email subject lines.

While flower shops will be dominating this holiday, you can definitely relate your own products to Mother’s Day.

Mothers enjoy electronics…

And clothes…

And shoes…

Even movies and games.

You see, Mother’s Day is a huge opportunity for marketers. Don’t let this spring pass by without honoring mothers everywhere.

Send out flowers to mothers, release a video thanking them, run a mothers-only contest, offer mothers a special deal or recognize them at a special event for mothers.

In this blog post, we’ll share our top picks for Mother’s day subject lines that will increase your open rate and, therefore, take subscribers towards a purchase.

We searched through more than 10,000 of our bigger brands’ Mother’s 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 rates.

Then, we’re also looking at the click rates for each spring subject line.

• #1 Mother’s Day subject line: “Mother’s Day Sale” – Open rate: 37%
• #2 Mother’s Day subject line: “25% Off Plus FREE Lip Gloss Mother’s Day Special 🙂 ” – Open rate: 32%
• #3 Mother’s Day subject line: “A Gift for Mom & A Gift for You!” – Open rate: 31%
• #4 Mother’s Day subject line: “Happy Mother’s Day Weekend!” – Open rate: 26%
• #5 Mother’s Day subject line: “Celebrate Mother’s Day with us!” – Open rate: 22%

With Mother’s Day subject lines, we see, again, that what some merchants would consider no-nos (putting a discount percentage, plus FREE, plus text-emoji) actually worked here.

A 32% open rate means the subscribers were interested and eager to engage.

If you don’t want to be too aggressive with the offer and subject line, you can always rely on more simple options. Take a look at Subject Line #1: even though it’s super simple, it was still effective (its open rate peaked at 37%).

When you’re creating Mother’s 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 then gets sent automatically to the rest of your recipients.
