100+ of the best Memorial Day email subject line ideas

Memorial Day email subject lines can increase open rates, clicks, and conversions when they create urgency, highlight discounts, or tap into seasonal shopping behavior. Memorial Day is a major USA holiday celebrated on the last Monday of May to honor fallen military service members. 

It also marks the unofficial start of summer. Many ecommerce brands run sales and promotions during this time. However, to run a high-converting holiday email campaign, you need subject lines that stand out. Your subject lines determine whether promotional emails get opened, ignored, or sent to spam. 

In fact, subject lines can have a direct impact on revenue. According to Omnisend, around 35% of recipients open emails based only on the subject line, while 69% mark emails as spam based on them. 

In this article, we’ll break down the best Memorial Day email subject lines. We’ll also share tips and email examples that can help you increase open rates and conversions in 2026.

Tips for writing Memorial Day subject lines 

To write Memorial Day email subject lines that increase open rates and conversions, focus on clarity, offers, urgency, length, emojis, A/B testing, content match, and timing:

1. Be clear, not clever: State the offer directly instead of vague phrasing. For example, “30% off Memorial Day sale” performs better than “You’ll want to see this” because readers instantly understand the value.
2. Include a special offer: During holidays, ecommerce brands run many promotions, so your subject line needs a clear incentive to stand out in crowded inboxes and increase open rates. Add discounts, free shipping, or bonus gifts.
3. Use urgency when it’s real: Use urgency messaging when a sale is ending soon, or products are limited. Phrases like “shop before the sale is over” help increase opens.
4. Keep it short: Omnisend email subject line best practices recommend 30 – 70 characters. This is so that subject lines don’t get cut off by email clients like Gmail.
5. Use emojis sparingly: Litmus reports emojis can improve performance, like opens and clicks, by up to 73%. However, overusing emojis can trigger spam filters, so first learn more about how to use emojis in subject lines.
6. A/B test variations: A/B test subject lines like “30% off Memorial Day sale” vs. “Ends tonight: Memorial Day deals.” Use tools like Omnisend’s A/B testing calculator to confirm which performs better based on real data.
7. Match the email content: The subject line should reflect the offer inside the email. This builds trust and reduces unsubscribes.
8. Highlight timing: Phrases like “this weekend” connect the offer to a specific time window. This encourages faster decisions before it ends, increasing open rates. 

Memorial Day email examples

Now that we’ve covered the best Memorial Day email subject lines, let’s break down some top-performing examples from ecommerce brands.

Vessel

Vessel uses an urgency angle by highlighting a clear 24-hour deadline in the subject line. The email also combines a strong emotional message (“gift of health”) with a clear product, price, and repeated “Shop Now” CTAs throughout the email. This gives readers multiple chances to click and buy:

On/Go

This brand uses an emotional angle in the subject line and email content. The email emotional hook “support military families” is paired with a relatable visual (mother + children). Then, it introduces a simple action-based offer (use code HONOR + 20% donation). It has one clear “Shop Now” CTA to guide readers toward one action:

Eight Sleep

Eight Sleep uses one of the most effective Memorial Day sales email subject lines by offering “early access” to subscribers. 

This Memorial Day email immediately introduces the offer of saving $200 with early access. It includes two CTAs — “Shop the sale” and “Get up to $200 off.” This increases conversions through exclusivity and price incentive:
