19 Types Of Thank You Emails To Customers + 25 Subject Line

Do you want to make your customers happy?

Sending thank-you emails is one of the simplest ways to do that. It’s a great way to show appreciation for their business and it can even increase customer loyalty. 

It’s also an opportunity for you to cross-sell or upsell products, services, or content.

In this guide, you’re going to learn:

So let’s get down to business.

What is a Thank-you Email?

A Thank-you email is used by businesses to build a healthier long-term customer relationship: by showing gratitude and appreciation to them.

Expressing thanks shows people how much you care and appreciate their time and generosity.

Remarkably, thank you emails help businesses gain customer engagement which results in great brand loyalty, in a way it does humanize the relationship between your business and your clients.

Why Should You Send Thank-you Emails?

Unlike buying directly from a store, customers don’t get to have that tangible experience with your business. For that, automated thank-you emails help you provide your customers with a feeling of reassurance from the time they have clicked the order button until they receive your product.

In particular, thank you messages are an approach to start assembling a relationship online that is like the in-person connections your clients have with physical brands.

When to Send a Thank-you email?

A thank-you email is a user-action based email. It means unlike broadcast emails, your thank you notes are triggered by specific user action to make sure your emails are sent at the right time, reaching out the right person.

And by a ‘user-action’ we do not only refer to placing an order, but there are also various occasions you can trigger your automated thank-you messages to be sent on.

You can automate your thank-you emails to:

  • High-value and loyal customers
  • Customers on their birthday
  • Event/webinar attendees
  • Anyone who’s written into support
  • Specific holiday thank you cards (Valentines, Christmas, new year, etc)
  • Newsletter subscribers
  • Job applicants and interviewees

How to apply these cases in practice? All you have to do is register for an email marketing automation software in which you can automate triggered thank-you messages based on users’ action.

Before sending thank-you emails as well as any other transactional messages, make sure to test their deliverability, spam score, and content.

For this purpose, you can use embedded solutions into a sending platform or an email testing service with a fake SMTP server.

7 Tips on How to Write a Thank-you Email to Customers

Our parents taught us how to say “Thank you” at a very early age, but a great thank-you email is not as simple as it seems. It is more than that, it is considered a customer delight.

When creating your automated thank-you email, consider the following 7 tips.

1. Say something positive in the subject line

The subject line is the first thing your customers will see when they open their inbox, so make it count! You should not just say “Thank you”. Try something a little more creative like: “Thanks for choosing us: your order has been shipped.”

A positive subject line increases your email open rate and provides a good first impression of your company.

Hence, the subject line is one way to say “Thank you” and make sure it counts! 

2. Write like a human

Even though thank-you emails to customers are transactional emails and one of the purposes is to automate, you should not just write like a robot.

“Thank You for your order!” – This sounds too robotic and impersonal!  

A good way would be: “Thanks so much again.” or even better if it’s possible with regards from who was responsible in fulfilling their request. 

Example: This is Adam from Tesla, Thanks!

Writing like a human is important since the company is reaching out to a customer and not another business. However, it doesn’t mean that you have complete freedom in writing anything but make sure there are no silly mistakes or typos!

3. Use the correct greeting

When sending a thank-you you email to a customer, you should use the correct greetings.

A good way would be personalizing your thank-you note with recipients’ first name. Instead of saying “Thanks for ordering” you can say “Hey Kenan, thanks for ordering.”

Personalized emails are proven to increase email click rate by up to 30%.

The first sentence of your email should be short and sweet, greeting and giving recognition for the customer’s purchase or support.

4. Express gratitude and appreciation

You can express gratitude at this point by mentioning something like how they helped make an important decision easier with their feedback on what product was best suited towards them.

You also make it easier for them to learn about the next step of the purchase, whether it’s from your side or theirs.

This is a great way to check-in and see if they have any questions about their order. 

It’s also an opportunity for you as the owner or manager to send a business thank you note.

You can show your excitement that this customer took advantage of what was offered by mentioning other products in which he might be interested from his purchase history.

You can say thank you in the: 

These emails are transactional, and adding a thank-you note to customers in each one doesn’t require a lot of resources.

7. Use an appropriate closing

Every email should have a closing. The best closings for thank-you emails are usually something like, “Thanks!” 

Or even better is to mention the product that they bought and ask them if there’s anything else you can help with related within your business services.

Sending an appropriate closing sentence in your emails allows readers to feel comfortable about their order and buying from you.

For example, you can ask your first-time customers to fill a form that includes their email address.

This can be done by adding them in some kind of remarketing list and sending emails on days that are most appropriate for their interests like Friday evening.
