In this blog, you’ll find 150+ engaging thank-you email subject lines to boost your open rates, plus expert tips to help you nail it. 🚀

Why does your eCommerce email marketing strategy require thank-you emails?

The reality of the internet is that it shows your customers your alternative almost every day. 

In this feast of options, your brand stands out with that extra impact thank you emails have on your customer’s psychology.

Dropping a thank-you email is like a secret handshake with your customers, acknowledging and appreciating their connection with your brand.

This strengthens the customer’s emotional bond with the brand by stimulating the feeling of satisfaction and happiness.

When customers feel valued, they are more likely to become repeat buyers and brand advocates because they feel they can reciprocate the gesture. 

You can send thank you emails for:

  • Newsletter sign-ups or account creation
  • Completed purchases
  • Positive reviews or feedback
  • Customer milestones (birthdays, anniversaries)
  • Post-campaign or sale appreciation
  • Survey or giveaway participation
  • Recognizing loyal customers or VIPs

Thank you emails are also a perfect opportunity to encourage further engagement, such as asking for reviews, offering exclusive discounts, or promoting related products.

For example, a skincare brand can suggest a matching moisturizer and sunscreen in their thank you email for a face cleanser purchase.

The idea is to use the opportunity wisely:

  • Suggest gifts in birthday thank-you emails
  • Highlight bestsellers in sign-up emails
  • Upsell and cross-sell in post-purchase emails
  • Request reviews to boost social proof
  • Offer exclusive discounts for repeat purchases

With so much riding on thank you emails, it’s important to craft the right subject lines for them to get opened in the first place.

9 pro tips from analyzing 100+ top thank you subject lines

There’s a LOT that goes into a good subject line. But don’t worry—we’ve analyzed 100 thank you subject lines from top brands to uncover the right best practices to follow.

Here they are:

1. Personalize it

Personalization boosts open rates.

According to the 2024 Litmus report, 77% of email marketing professionals believe subject line personalization improves performance.

Simply including your recipients’ names in thank you email subject lines goes a long way. It makes them feel individually recognized and creates a sense that the communication is tailored for them.

2. Add special offers or benefits

If you’re offering something in return with your thank-you note, be sure to include it in the subject line.

The offer entices recipients to open the email and drive further engagement and purchases.

3.  Add excitement and urgency

You can add phrases like “limited-time deal” or “only a few left” to prompt recipients to act quickly. But only do it when you have exclusive offers or time-sensitive promotions to promote. 

4. Use Emojis (When Appropriate)

Emojis grab attention and add warmth to your message but you should carefully consider when to add emojis. Don’t use emojis for the sake of it, it can harm your open rates. 

Using one or two well-placed emojis in selective subject lines is a better approach. 

➡️Check out our guide on using emojis in subject lines here for more emoji usage tips and best practices.

5. Keep it short & direct

Subject lines with less than 70 characters tend to perform well. Make sure to keep your thank you email subject lines short, crisp, and direct for both desktop and mobile users.  

6. Emotional appeal

You can also try to incorporate heartfelt language in your thank you email subject lines to create a stronger emotional bond.

For example: “From the bottom of our hearts… and dog bowls.” — Bark.

This not only conveys genuine thanks but encourages brand loyalty through a relatable tone.

7. Consider seasonal or event-specific messaging

If you’re sending thank-you emails for special occasions, birthdays, or anniversaries, be sure to tie the thank-you to the occasion in the subject line.

For example: “Thank You Day Special: Get Pampered with Luxurious Skincare”- Glow Essentials.

It connects gratitude to a specific celebration, making the email feel timely and thoughtful.

8. Use humor or a playful tone

A little humor or wit in your subject line can help you stand out and bring a smile to the recipient’s face, creating a positive impression of the brand. But the key is to not force it and do it when it feels right.

For example: “Thank you berry much” – Bubs Warehouse International.

9. Test different variations

No matter how well you write your subject line, you want to make sure it’s actually a good one. 

How do you make sure? With A/B testing. 

Chances are you’ll come up with a few different subject lines you think could work, or there were a few examples above that caught your eye. That’s good.

Having multiple subject lines in mind for your thank you campaign means you can run some A/B tests. In other words, running two subject lines at the same time to see which one generates the best open rate.  

This way, you’ll have hard data backing up your decision and the confidence you’re maximizing your open rate. 

Especially when you run your A/B tests properly and not just test random subject lines based on what pops into your mind. 

📌We’ve put together a detailed guide on how you should approach A/B testing that explores this in much more detail here
