Reading Time: 7 minutes

Mother’s Day, celebrated on May 11, 2025, in the United States, is a heartfelt occasion for showing appreciation to mothers.

It’s crucial to craft engaging and creative Mother’s Day email subject lines to effectively convey your customers’ gratitude.

This holiday, dominated by flower sales, presents a wide range of opportunities for marketing various products, from electronics and apparel to entertainment like movies and games. As a marketer, seize this chance to honor mothers – consider unique approaches like sending flowers, creating thank-you videos, organizing special contests or events, and offering exclusive deals for mothers.

This blog post will guide you through the best Mother’s Day subject lines to boost your open rates and drive sales.

In this article you will find:

Top 5 best performing Mother’s Day subject lines (based on Omnisend research)

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: “LAST CALL for Mother’s Day Delivery” – Open rate: 69.25%
• #2 Mother’s Day subject line: “Mother’s day is around the corner” – Open rate: 48.2%
• #3 Mother’s Day subject line: “Mother’s day survival kit 🧰” – Open rate: 42.2%
• #4 Mother’s Day subject line: “Mother’s Day Sale” – Open rate: 37%
• #5 Mother’s Day subject line: “Happy Mother’s Day! 💓” – Open rate: 35.42%

These results demonstrate that even subject lines with elements typically considered less effective — such as discount percentages, the word “FREE,” and emojis — can perform exceptionally well.

For instance, a 35% open rate indicates strong subscriber interest and engagement.

If you prefer a more subtle approach, simpler subject lines can also be effective. Consider the first subject line above: despite its simplicity, it achieved an impressive open rate of over 69%.

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 two subject lines or sender 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.
