A good holiday email subject line can be the difference between someone opening your email and deleting it. With inboxes getting especially busy this time of year, generic lines are easy to overlook.
What you write should depend on the email and the people reading it. A gift guide, a flash sale, and a product launch don’t all need the same kind of subject line.
You might go with something playful, such as “🎁 Your holiday treats are ready,” or choose something more understated, like “Curated holiday collection.”
Below you’ll find 100 of the best holiday email subject lines to inspire your campaigns this festive season.

What makes a holiday subject line work
A holiday subject line works when shoppers can read it at a glance and see a reason to open. An iPhone in portrait mode shows only the first 41 characters, so keeping it short matters.
Here are some findings from our internal research:
- Keep it short: Shorter subject lines can help improve open rates. The sweet spot is five to seven words, based on our Black Friday and Cyber Monday (BFCM) analysis of more than 5,000 subscribers.
- Stick to 40 characters or less: Your subject line may look fine on desktop but get cut off on a smaller screen. Most platforms cut off around 50 characters, while some devices show fewer than 40. Use our free subject line tester to see how yours holds up.
- Know your benchmark: The average email open rate reached 30.7% in 2025, according to our 2026 ecommerce marketing report. Our email marketing benchmarks put holiday and seasonal stores at 47.62%, versus a 30.22% overall average. For your seasonal campaigns, compare your results with 47.62%.
- Send when shoppers read: Start with 9–11 am if you’re unsure when to send. Our 2026 send-time research analyzed about 26 billion emails and found Tuesday had the highest open rate at 31.27%.
- Go light on emojis: When using emojis in subject lines, stick to one or two. Also, preview them in different email clients, as some can show boxes instead of emojis.
The best time to send an email is 9–11 am and the best day is Tuesday; Holiday campaigns have a 47.62% open rate, and short messages perform well.

Tips for crafting effective holiday email subject lines
The best holiday subject lines give shoppers a clear reason to open the email. Keep them short, make them personal, use deadlines, and create emotional triggers.
Here are six practical tips to help you write subject lines that get noticed:
- Use the Omnisend email subject line generator: Stuck on what to write? The subject line generator gives you five ideas to work from, with another five available if you want more options. You can use it directly while creating your campaigns.
- Personalize your messaging: Use details you already have, such as a customer’s name, wishlist items, or past purchases. These details make the subject line feel more relevant to each reader.
- Use authentic urgency: Don’t tell shoppers something is “ending tonight” if it isn’t. Use real deadlines, genuine offers, and accurate stock information when you want people to act quickly.
- Spark curiosity: Don’t give shoppers every detail in the subject line. Instead, tease something they’ll want to see, whether that’s a product reveal, a surprise offer, or your holiday pick. A line like “Our top perfume revealed🥇” gives readers enough information to get interested without giving away the answer.
- Create emotional triggers: Use the emotions that naturally come with holiday shopping instead of filling your subject line with seasonal buzzwords. Gift anxiety, family connection, hobbies, pastimes, and holiday cheer can all give you a stronger starting point for your message and help it feel more relatable.
- Get seasonal: Don’t make shoppers guess which holiday you mean. Mention it in the subject line and check out these Thanksgiving email subject lines or Christmas email subject lines for ideas. Naming the holiday makes the email feel timely.
Write your own with the subject line generator
The 100 subject lines above are ready to copy. Use our free AI subject line generator when your industry or offer needs something more specific.
That happens when none of the lines match your specific campaign, such as a Boxing Day sale on winter coats or a gift guide launch for a new collection.
Enter at least five keywords and an idea of your email in 30 to 50 characters into the subject line generator. Mention the campaign type, your audience, and a tone, such as urgent or playful. It returns a set of lines, and you can ask for five more.
Edit the results to match your brand voice. Then check each line’s length in the subject line tester before you send.
Conclusion
The holiday season is a great opportunity to drive more sales through email. Start by getting the subject line right, because that’s what shoppers see before they decide whether to open.
Give them something worth opening for. Use a customer’s name or preferences, highlight a real deadline like a “24-hour flash sale,” or reserve an offer for VIP members. An emoji can also add some personality if it suits your brand.
After that, don’t rely on your gut to decide which version works. Try different subject lines, and test your email content and design too. With Omnisend’s split-testing feature, you can compare subject lines, interactive elements, and content to find the combination your audience responds to.
