Better than recover users that have churned, is to prevent them from churning in the first place. Let Liquid machine learning identify them for you and act before they leave.
When you use Liquid's Formulas, you'll select the audience, the action and the time.
Users that are identified with high-churn probability (through Liquid machine learning algorithm)
Send an In-App Message with a benefit for the user to keep using the app
Next time the users enters the app
Define a custom segment with users with a high probability of churning. This is an attribute of each user identified by Liquid machine learning algorithms.
Select In-App Message as the action and write a message detailing what the user benefits with the app or offering a discount on the next purchase.
Select “Send now” so the next time the user opens the app it receives the message.
