Send a subscription cancelation email to app users

Collecting feedback from users who cancel during a trial is essential for improving conversion rates and enhancing the overall trial experience of an app. This tutorial outlines a process using Subscriber Attributes and Zapier to send customized feedback surveys to users when they unsubscribe from a free trial, without the need for server code. By capturing user emails and favorite workout preferences during onboarding and utilizing Zapier to handle subscription status changes from RevenueCat, the process filters events to target only trial cancellations. A personalized email survey is then sent to these users, encouraging them to share their reasons for cancellation, with the goal of identifying areas for improvement. The tutorial also provides an optional step for tracking survey recipients using the RevenueCat REST API and suggests extending the use of Subscriber Attributes to engage users at other critical points in the app.
