Rezoki is an AI agent that automatically calls and emails your failed-payment customers — so you recover revenue without lifting a finger.
Trusted by SaaS founders recovering revenue automatically
The problem
Payment failure emails get a 12% open rate. Your customers never see them.
You're busy building. Manually chasing payments is the last thing you want to do.
Every failed payment that goes unrecovered is pure MRR loss — forever.
How it works
One Stripe webhook is all it takes.
Paste one webhook URL into your Stripe dashboard. Takes 60 seconds. Rezoki starts listening immediately.
The moment a payment fails, Rezoki fetches the customer's details from Stripe and opens a recovery job automatically.
Rezoki sends a personalized email, then follows up with an AI voice call — using your own voice if you want. Then repeats on a schedule until they pay.
When the customer pays, Rezoki marks the job as Won and logs the recovered amount to your dashboard.
Features
Rezoki calls your customers with a natural AI voice. Clone your own voice for a personal touch.
Use your own email. Zero email costs. Outreach comes from your domain.
Customize the exact timing and order of emails and calls. Sensible defaults ship out of the box.
Every email sent, every call made, every outcome — logged against the recovery job in real time.
Cancelled users get periodic calls about new features. Churned customers are warm leads.
No complex integration. One URL in Stripe and Rezoki handles everything automatically.
If you already have failed payments sitting in your Stripe account, Rezoki can scan your entire history and immediately start recovery sequences for every missed opportunity — not just new ones going forward. Add your Stripe API key, click scan, and Rezoki imports every open invoice and cancelled subscription automatically.
