Be honest about who Stunning is right for
If your failed payments are overwhelmingly low-value, self-serve renewals, and you want dependable automated email recovery with minimal setup, Stunning does that well and has done it for over a decade. You may not need what Chaser adds. Buy the simpler tool when the simpler tool fits.
When Chaser is the better fit
Choose Chaser when your book has high-value or anchor accounts mixed in, where a templated "your payment failed" email forwarded inside a major customer costs you more than the invoice. Chaser classifies every failure by root cause, holds VIP accounts back from automation by design, and routes unresolved cases (plus anything your VIP or threshold rules flag) to a command center with full context and an AI-drafted note in your voice that a human approves. That is a different job than email sequences, and it is the job Stunning does not try to do.
Stunning is email automation for failed payments. chaser.cash adds the layer Stunning does not have: a command center for unresolved cases, human judgment on VIP accounts, cancellation interception, and an MCP server for agentic workflows.
If email automation is all you need and your accounts are low value, Stunning is simpler. If you have high-value accounts that need human judgment before an email goes out, chaser.cash is the right fit.
Where Chaser is still early
Founding-partner beta. In-app recovery surfaces (banners, paywalls) are in preview; native CRM and ledger connectors are on the roadmap. The live loop today is email plus a Stripe-tokenized hosted card-update page. Stunning's email dunning is mature and proven; if all you need is that, its track record is a fair reason to choose it.
