How do you track churn reasons in SaaS without annoying users?

Honestly the best results I've seen come from a single-question in-app modal right at cancellation — something like 'What's the main reason you're leaving?' with 5-6 preset options plus a short text field. Tools like Churnkey or even a simple Typeform embedded in the cancel flow keep friction low. You'll get way more responses than a follow-up email survey, and the data is actually actionable.
