Tips on Creating Eye-catching Thank You Email Subject Lines

A well-written thank-you email helps to improve relationships with the recipient, increase brand awareness, and even track leads. Obviously, having a great email subject line is important, but knowing how to create an eye-catching email matters, too.

Here’s a good example of a thank-you note from Clinique.

Subject line: From us to you: Thank you!


What worked well?

  • Show appreciation in the email subject line.
  • Include a brand logo in the picture.
  • Identify the reason for being grateful.
  • Add contact information.

So, wouldn’t it be great if you could create a similar thank-you email that stands out from the crowd? To create an amazing thank you email, take into account the following tips.

Segment your email list

From time to time, you have to send bulk emails to recipients. Although personalization matters, you can segment your email list to create the right thank you email marketing campaigns for the same audiences. 

As specified in Webopedia, targeted email marketing is a modern technique that  

identifies a specific audience for a personalized email campaign and helps you create the right message for a group of people.

Use powerful words

With the right words in your subject line and email, you can encourage readers to open it, learn more about your company, and increase clicks. It’s psychologically proven that powerful words can improve your email marketing effectiveness.

Include emojis that show appreciation and evoke positive emotions

Most people are visual learners with a short attention span, so using simple visual elements like emojis help to evoke emotions and create a bond with recipients.

Here are the most popular emojis for thank-you email subject lines:
😇 – face with halo
🤗 – hugging face
👏  – clapping hands
🙌  – raising hands
🙏  – folded hands (for donation and non-profit organizations)
🤝 – handshake (for partnership emails))

Test several subject lines

You never know what can work best for your audience. Thus, A/B testing is a good option when it comes to writing great subject lines. What is more, it’s a good idea to create a separate thank you follow up email subject line when sending additional emails after no-reply.

Be creative in showing appreciation for recipients

Having a well-written thank you email subject line is great, but you can also show your appreciation in an email signature as it can leave the reader with positive emotions.

Your Turn with a Thank You Email Subject Line

The email subject line is the first thing your email subscribers see when they receive an email from you. It doesn’t take much time for people to scan it and make a decision whether they want to open your email or not.

When it comes to writing thank-you letters, it’s highly important to hook your reader’s attention with the right thank you email subject line. Thus, it’s your turn to analyze your audience, make up several subject line ideas, and test what works best for your audience.
