AI-Powered Dunning Emails
Generic payment failure emails get a 12% open rate. Rezoki's AI-crafted dunning emails are personalized, perfectly timed, and sent from your domain — achieving 3x higher engagement.
Get StartedRezoki generates personalized dunning emails using AI that understands your customer's context — their plan, tenure, payment history, and the specific reason their payment failed. Each email is crafted to be helpful, not threatening, and sent from your own domain so it looks like it comes from your team. The AI optimizes subject lines, send timing, and follow-up cadence based on what works for your customer segments.
The Problem
Standard payment failure emails are generic, impersonal, and easy to ignore. They all look the same: "Your payment failed. Update your card." With open rates around 12% and action rates below 3%, most failed-payment emails never lead to recovery. Meanwhile, the clock is ticking — the longer a payment stays failed, the less likely the customer is to come back.
How It Works
Payment Failure Detected
When Stripe reports a failed payment, Rezoki instantly captures the decline code, customer details, and subscription context.
AI Generates Personalized Email
Our AI crafts a unique email considering the customer's name, plan, how long they've been a subscriber, the specific failure reason, and optimal tone for their segment.
Sent From Your Domain
The email is delivered through your own SMTP/domain, so it appears in the customer's inbox as a message from your company — not a third-party dunning service.
Smart Follow-Up Sequence
If the first email doesn't lead to recovery, Rezoki sends follow-ups with escalating urgency, different angles, and optimized timing — all AI-generated and unique.
Track and Optimize
Every email's open rate, click rate, and recovery conversion is tracked. The AI learns what works for your audience and improves over time.
Key Benefits
3x Higher Open Rates
AI-personalized subject lines and send timing achieve open rates of 35-45% compared to 12% industry average for payment failure emails.
Your Brand, Your Domain
Emails come from your domain with your branding. Customers see a message from you, not an unknown third party, building trust and increasing action rates.
Context-Aware Messaging
A loyal 3-year customer gets a different email than a 1-month trial. The AI adapts tone, urgency, and messaging based on the customer's value and history.
Multi-Language Support
Generate dunning emails in your customer's language — English, German, French, Spanish, Portuguese, and more — with culturally appropriate tone and conventions.
Zero Manual Effort
No templates to write, no sequences to configure for each customer. The AI handles everything while you focus on building your product.
Real-World Use Cases
Scenario
A high-value enterprise customer's card expires
Outcome
Rezoki sends a personalized, warm email acknowledging their 2-year subscription, explaining the card expiry, and providing a one-click update link. 78% of enterprise customers update within 24 hours.
Scenario
A new trial-to-paid subscriber's first charge fails
Outcome
The AI sends a friendly, non-alarming email explaining that the first charge didn't process, with clear instructions. The tone is welcoming, not punitive — protecting the new relationship.
Scenario
A mid-tier customer ignores the first two recovery emails
Outcome
Rezoki escalates with a third email that takes a different angle — perhaps highlighting what the customer will lose access to, or offering a temporary payment plan — increasing the chance of re-engagement.
