Core product — Email Agent

The reply is where the revenue is. Resub answers it.

When a failed-payment email gets a reply, Resub classifies the intent, negotiates within the playbook you set, and executes the save directly in Stripe — pause, downgrade, discount, or a card-update link.

Recovered
Hey Emma, your FreshVitamins payment didn't go through — usually just an expired card. Want a quick link to update it?
Wait, what's this charge? I don't remember signing up.
No worries! Your Daily Essentials pack from January — $47/mo. Your card just expired. Want the link to update it?
Oh right, I do use those. Send it over.
Card updated — payment recovered, $564/yr at full price

Outcome
In progress

Simulated demo, modeled on common recovery conversations. Resub adapts to your products, pricing, and playbook.

Guardrails

An AI you can hand the keys to.

“What stops it from promising my subscribers the world?” Four enforcement layers plus full auditability — your playbook limits are physical, not polite suggestions.

Disabled offers don't exist

If you don't allow discounts, the discount tool is never built for the conversation. The AI can't use what it doesn't have.

Hard numeric limits

Pause days and discount percents are schema-clamped. A 90-day request against a 30-day max is physically rejected.

Every reply re-validated

After the AI writes a response, a separate validator re-checks it against your rules before anything sends.

Escalates like a pro

Anger, confusion beyond its depth, or an explicit ask for a human hands the thread straight to you.

Full transcripts, always

Every message in and out is stored with intent, actions taken, and cost — auditable from your dashboard.

Your domain, your reputation

White-label sending from your own domain with proper threading. One-to-one transactional replies, not bulk mail.

Every failed payment is a conversation waiting to happen.

Your dunning tool retries the card. Resub has the conversation that saves the subscriber.
