Let’s admit it, we all have an email list we subscribed to but we never open an email or click a link to a page. It is just a fact.

But as an email marketer, you shouldn’t accept the fact that some contacts lose touch. Instead, you MUST wake the sleeping contacts in your mailing list and try to re-activate them back again with re-engagement email campaigns.

With effective re-engagement campaigns, you can get customers back, and it costs cheaper than acquiring new ones.

In this guide you will learn:

  • Why should you use a re-engagement email campaign
  • How to detect inactive contacts
  • 6 tips in how to write re-engagement emails
  • 12 of the best re-engagement email examples
  • How to create a re-engagement email campaign to win back customers
  • 29 re-engagement email subject lines to win back inactive email subscribers

So let’s get to work.

Why Should You Use a Re-engagement Email Campaign

Your new email subscribers show high engagement with your brand, yet, some subscribers turn to inactive contacts after some time. 

Here are a few reasons why it happens:

  • They lost interest in your newsletter, product or service
  • They found an alternative to your solution
  • They didn’t understand all the benefits that your product offers
  • They simply forgot about you

Subscribers turn inactive, that is a reality. And that is why you should use re-engagement email campaigns.

According to Invesp, turning an inactive subscriber into a customer costs 5 times cheaper than acquiring a completely new customer, where inactive subscribers generate 7% of overall business revenue.

Instead of increasing your budget to acquire new customers, you could start creating re-engagement email campaigns and achieve the same result with fewer resources.

How to Detect Inactive Contacts

Inactive contacts are contacts who have not interacted with your email campaigns during the last 1-3 months.

Determining whether a contact is ‘active’ or ‘inactive’ doesn’t have one true answer. It largely depends on how you define an active contact.

A common way to detect inactive contacts is by the lack of email opens.

Track how long it has been since a contact last opened an email from your company. Check their open rate or click-through rates for emails sent in the past 2 months.

It’s important to detect inactive contacts before sending re-engagement campaigns, as these types of emails can be annoying for active contacts.

Some people believe that if they do not interact with the company’s emails for some time, then the company should no longer contact them at all.

How to find inactive contacts who didn’t interact with your emails?

Probably the email marketing software you use provides you with behavior-based filtering to detect inactive contacts and send them re-engagement emails for a chance to win them back.

For example, here is how it’s done in Automizy. You can filter your contacts based on opened/clicked emails.

How to detect inactive contacts

Then add the 5 last campaigns you’ve sent to your contacts and select “not opened” to filter the contacts who didn’t open your last 5 emails.

What to do once you’ve detected the inactive contacts?

You’ll have to label them using contact tags so you can trigger a re-engagement email sequence just for them.

6 Tips on How to Write Re-engagement Emails

1.  Give your contacts a reason to stay engaged

Give your contacts a reason to stay engaged by showing them the value of staying subscribed. This could be anything from product updates, new products on sale, or exclusive offers for subscribers only.

You can also show how you’ve been using their feedback and include testimonials saying how great it is that they’re still with you!

Winning back your inactive customers costs less than acquiring new ones, so don’t give up.

2. Show that you value your contacts

Show that you value your contacts by thanking them for staying with you. 

You can also show how much they mean to the company and include personal messages from different members of staff who interacted with them previously to show that the people behind the business care.

3. Get emotional

Get emotional by showing how much the company will miss their customer if they unsubscribe.

This could be a message from the CEO, or some humorous graphics highlighting what it feels like when they’re no longer on your list and missing out on all of the great content you share with them.

The purpose of this email is to show that while your customers may have forgotten about you, for now, there’s always a chance they’ll come back in the future. 

And at least they know you care enough about them to send an email reminding them. 

Check the Duolingo re-engagement email example in the next section to see how they got emotional to re-engage inactive users.

Don’t forget: The best re-engagements are those triggered automatically so don’t start mailing everyone – follow the next sections to find how it’s done.

4. Ask questions

Most people find email challenging, especially the unsubscribe process. Offer your readers a way to get back in touch with you so they can learn about upcoming content or share their feedback on previous emails.

Asking your inactive contacts questions helps them remember why they signed up for your list in the first place.

Questions can also put them on a path to help you solve their problem, or provide valuable insight into what’s holding them back from engaging with your content and purchasing your products/services.

5. Include a CTA to click if they still want to hear from you

Since you already know they’re “inactive” at this point, don’t leave them hanging.

Let them know that if they still want to hear from you and learn about your new content, or get notified of a sale.

One way of doing that is by including a CTA button that they can click if they’d still want to hear from you.

“If you’re still interested in hearing from us, click here.” 

It’s a simple and unexpected way of saying “yes I’m still talking to you”. This type of CTA also has the added benefit that helps win back inactive contacts.

You don’t have anything to lose by including this line at the end of an email because even if someone doesn’t click, most likely next time they’ll unsubscribe from your list.

6. Provide an opt-out option

You must include an unsubscribe link or an opt-out option in every email.

Don’t try hard to keep inactive contacts in your list. I mean everyone wants a larger list. But, if your list is filled with inactive contacts your email analytics won’t be accurate.

The cleaner the email list, the more accurate analytics you have.

An unsubscribe is always better than a contact who’s “dead” on your list.

How to Create a Re-Engagement Email Campaign to Win Back Inactive Customers

You don’t want to be crying over customers who did not show any sign of engagement during the recent month or two.

"please come back" gif

You can set up a re-engagement email sequence in Automizy’s email automation software.

Your re-engagement campaign is mainly an automated email campaign with a series of emails to win-back customers.

Let me walk you through the process, step by step.

1. Identify inactive contacts

As explained above, among the first steps to re-engage inactive contacts is to identify these people and label them with a contact tag.

A contact tag is a label that adds information to your email contact. For example, you can add the tag “Inactive” to those who didn’t open your last 5 campaigns.

First thing I set up a filter based on campaign activity, I have the list of inactive contacts.

Find inactive contacts based on who opened your emails during the las month or two

And then select and label the 25 contacts I filtered with an “Inactive” tag which I will use in the next step as a trigger.

2. Set up a re-engagement email trigger

After you identify the inactive contacts and tag them, now you’ll need to set up an automated email sequence to trigger re-engagement emails to those contacts.

In Automizy, you can trigger an automation when a contact gets a tag:

Re-engagement email campaign trigger

This allows you to select the tag “Inactive” to launch the re-engagement emails only to contacts you’ve identified and labeled in the previous step.

2. Add your re-engagement emails

After setting up your trigger, your next step is to add your re-engagement emails.

Add re-engagement email template

Using Automizy, you can create responsive email templates without any coding knowledge.

Drag and drop different email elements, fill them up with your content, choose your colors and you’re ready.

There is a default padding and design setup that looks great without any modification. Feel free to use the default setting and build your mass email newsletter in 20 secs!

When you finish designing your re-engagement email, you can preview and add it to your sequence.

You’d want to be more persuasive and add more emails to your sequence and follow up on contacts who don’t show any sign of engagement.

Follow the next steps to learn more about it.

3. Add the waiting period and condition

To add more emails to your re-engagement sequence, you’ll have to start with adding a wait period and segmenting your contacts.

This step consists of adding:

  • Wait period
  • Condition: email open

Apply a “wait period” before you set your email open condition.

Give your contacts some time to interact with your email. It will also help you to be more accurate to whom you want to send follow-up emails.

Add wait period after re-engagement email

After the waiting period, apply the condition “Has opened an email” and split your automation for the two branches, “Yes” branch and “No” branch.

Segment inactive contacts based on opened email

4. Remove “Inactive” tag to email openers

Users go on the “Yes” branch if they’ve opened the first email and you managed to re-engage.

In this case, you create an action by clicking on “Do this”.

add action in re-engagement email sequence

Then click on “Remove tag from contact”.

Remove inactive tag for engaged contacts

Then you just select to remove the “Inactive” tag to contacts who opened the re-engagement email and showed a sign of engagement.

5. Follow up on cold contacts

Cold contacts are the ones who didn’t interact with your engagement email.

You can still give it another try to re-engage them by sending them another last-chance email.

If they open your email and engage with you, that’s a win for you. And if they’re not showing back any interest, you can remove them automatically from your list.

Remove inactive contacts from email list

By setting up a similar re-engagement email sequence, you’ll be able to win-back inactive contacts and exclude the unengaged ones from your future emails.

When complete, the whole sequence would look like the following:

Using email software like Automizy helps you automate your re-engagement campaigns and save you time and energy.

Winning-back inactive contacts have a lot to do with getting them to open your re-engagement email.

And the number one factor that affects open rates is the subject line. Let’s see a list of re-engagement email subject lines that you can use to increase your email open rates.
