Why Re-engagement is a High-Value Move for Your Business
A growing list of unengaged contacts creates a silent risk to your marketing performance and long-term reach. When a significant portion of your audience stops opening your emails, it signals to inbox providers like Gmail and Outlook that your content may be irrelevant or unwanted. In addition, sometimes a reminder about the benefits of your services is all it takes to remind a previous customer of your value. In this guide we'll demonstrate how to set up an automation that will re-engage your contacts over time.
To Get Started
Log in to your Keap application.
- Navigate to the Send a Broadcast email section:
For Pro / Max users: go to Marketing → Email broadcasts.
For Classic users: go to Marketing → Email & Broadcasts.
On the Email Broadcast page click Create email broadcast

Select who the Sender of the email
Add your subject line

-
Add your audience
Click in the box and search for the tag you created in the previous process and select the tag

Create your re-engagement email. Write a re-engagement email asking if the customer is still interested in hearing from your business. Let them know they'll be opted out of future emails unless they choose to stay subscribed. Include a clickable link in your message (highlight the text, select Link, then enter your desired URL). When a contact clicks the link, apply a “Re-engaged Contact” tag to them.

Click Save and exit

18 Month Unengaged Contacts
As a user of Keap, you are able to enjoy the benefits of the combined deliverability reputation of all Keap users. This combination of authority results in highly deliverable emails that are more likely to reach your contact's inbox. Because of this, Keap has safeguards in place to ensure that the reputation of all our senders is protected.
When one of your contacts has been unengaged with your Keap platform for a period of 18 months, they are automatically marked as non-marketable and emails can not be delivered to them. There is not a manual way to mark them as engaged, or any other way to manually force Keap to send to them. As a Keap user, your only recourse is to send them a re-engagement email as described in this guide, and this will give them the ability to re-engage themselves.
Key Elements of a Successful Re-engagement Email
Personalization:
Use the recipient’s name and, if possible, reference their past behavior, purchase history, or preferences.Clear Call to Action:
Tell recipients exactly what you want them to do (e.g., click a button, complete a survey, visit your site).Compelling Subject Line:
Grab attention and clearly communicate the intent of the email.Concise, Engaging Content:
Keep the message focused, benefit-driven, and easy to read.Incentives (Optional):
Consider including a discount, free shipping, or bonus offer to motivate action.Segmentation:
Tailor your message to different groups of inactive contacts (e.g., based on product interest or inactivity duration).Testing:
A/B test subject lines, content, send times, and offers to optimize performance.
Final Tip
If contacts do not re-engage after a re-engagement series, consider removing or suppressing them to maintain a healthy sender reputation and comply with inbox provider expectations.
