Cancellation Follow-up
Send this right after a customer cancels. It confirms they will not be charged again and when access ends, then asks one question with four one-click reasons, plus room to reply in their own words. Match the access and data lines to your real policy, link each reason to your survey, and keep the reactivation link at the bottom.
Loops
Confirm first, ask second
Trigger it from the cancellation event your app or billing system sends. With the Stripe integration, that can be customer.subscription.deleted. Only state the access end date and data retention your product supports, and give each reason its own link so answers can be counted. The churn prevention guide covers what to do with the answers. Save any win-back offer for a later email.
