Show IH: Validating a dunning tool for Polar & Creem sellers (Stripe has 10+ options, they have zero)

Stripe sellers have a dozen tools for recovering failed payments — smart retries, dunning email sequences, recovery dashboards. Polar and Creem, the newer merchant-of-record platforms a lot of indie devs are moving to, have none of that.

Built a landing page to validate demand before writing any code: https://recoup-waitlist.netlify.app/

If you're selling through either platform — is this a real pain point, or am I overthinking a problem that doesn't actually cost anyone much revenue? Genuinely want to know before I build.
