What Stunning does well
Stunning has been recovering failed Stripe payments for over a decade. It sends retry-aware dunning emails, warns customers before their card expires, and gives them an easy way to update billing details. It is Stripe-native, reliable, and focused. If your only leak were involuntary churn, it would be a reasonable pick.
Where it stops
Stunning handles involuntary churn only. When a subscriber clicks cancel, deliberately choosing to leave, Stunning plays no part in that moment. For most SaaS businesses voluntary churn is the bigger half of the leak, and it is also the half where the right offer at the right moment actually changes minds.
The pricing model matters too. Stunning charges a flat monthly fee whatever happens. In a month where it recovers little, you pay the same as a month where it earns its keep.
How SaveMyChurn approaches it differently
SaveMyChurn covers both halves of churn in one tool. It recovers failed payments with automated dunning, and at the cancel moment an AI makes a genuine per-customer decision: offer a pause, offer a targeted discount, or let them go, based on the full context rather than a blanket discount for everyone.
The commercial terms are aligned with results. It is free to start with no card, and the free tier simply takes 15% of the revenue it actually recovers. Growth (£49/mo) drops the commission to 10% and adds AI cancel-flow conversations, and Pro (£399/mo) drops it to 5% with white-label and custom rules. If nothing is recovered, the free tier costs you nothing.
The bottom line
If failed payments are truly your only problem and you like a flat fee, Stunning is a solid, proven dunning tool. If you want the whole churn leak handled, failed payments and cancellations together, with pricing that only earns when it recovers real revenue, SaveMyChurn is the sharper fit for a Stripe-first founder.
