Since the tangible aspect is missing for online business, online customers love when their shopping experience feel personal.

That’s why businesses working hard on showing gratitude to their customers humanizing the relationship, and automated thank-you emails are a way of doing so.

A thank you email is not just an email you send when customers buy from you. It is more than that.

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.

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

  • Say something positive in the subject line
  • Write like a human
  • Use the correct greeting
  • Express gratitude and appreciation
  • Include specific details
  • Say thank you again

How to Automate Sending Personalized Thank-you & Birthday Emails

You can easily set up your personalized thank-you emails in Automizy and trigger different thank-you messages to specific targeted contacts, based on their actions on your website.

Here is a list of triggers you can set up for your thank-you emails:

You can set up a basic thank-you autoresponder email to your customers, that consists of a one single thank-you message triggered on customer’s order.

It looks like the following example:

You can also make your thank-you autoresponder as a drip email campaign to greet and welcome your new blog subscribers.

Autoresponder drip campaign example in Automizy welcome new subscribers

Whenever a new subscriber opt-in for your blog newsletter a thank-you email is sent immediately to introduce your business and say “thank you for subscribing”.

Followed by 1 day wait period, subscribers receive their first blog newsletter, and right after a couple more days, another automated newsletter is sent.

With similar automated email sequences, you make sure that subscribers stay close to you, starting from the moment they have subscribed and most interested in what you have to offer.

You could use triggered email sequences with conditions.

Trigger an email to be sent on a specific milestone, special holidays or contact birthday to spice a little bit the relationship with your prospects and customers.

Based on that trigger an email and show appreciation to your customers on their birthdays. It’s important to offer a small gift within the email, something like a discount, coupon, gift card, etc.

After the birthday email, insert a waiting period of 2 days to check if your customer clicked on the gift link and claimed it. If someone claimed the gift, you could send a follow-up email.

For those who did not click the gift link on the birthday email, you can offer them a second chance to claim it.

Lastly, if you want a thank-you note to all your contacts on a business milestone you recently reached, you could send personalized bulk email campaign to show appreciation to your customers.

Personalized thank-you bulk email campaigns would be useful for:

  • Interview thank you email
  • Thank you emails after meetings
  • Follow up thank you email after meeting
  • Thank you email after sales interviews
