The old way
The retention moment is buried in a thread nobody tagged.
“Why was I charged?”, “cancel my plan”, “my payment failed.” Every one is a save you could make — and a dig through Stripe in another tab, while the churn signal reads like every other email.
How it fits together
The intent gets read, the account renders, the save gets drafted.
Support runs on one engine, in three beats — and every beat is pointed at one number: the MRR you keep. The billing email lands, the inbox reads the intent, the account renders, and you approve anything that sends.
It reads the intent, not just the words
A Skill recognizes the customer and the billing intent — a charge query, cancel intent, a failed payment — and pulls the live account from Stripe. On every billing email, it knows whether you're looking at a question or a churn risk.
The account, where the question is
Plan, status, MRR, renewal date, and the last invoices render as a card in the thread, with hosted-invoice links. The retention moment is on screen the second it arrives, not buried.
It drafts the save, you approve it
On a schedule, an agent drafts the grounded reply — a retention offer for cancel intent, an “update your card” for dunning — and queues it for your one-click yes. Every send is reversible and waits for you.
What changes
The account on screen, the meter on your side.
The account, in the thread
Plan, status, MRR, renewal date, and the last invoices with hosted-invoice links render right where the customer wrote in. Answer billing — or close a save — without leaving the inbox.
Catch churn before the account's gone
Cancel-intent mail gets a retention draft; dunning mail gets an “update your card” draft. Relay a Stripe webhook and a failed payment surfaces the instant it happens, not at the next statement.
One ledger for every send
Resets and receipts, product updates, support — all from your domain, off one ledger with exactly-once delivery you can audit. One sender to warm, one reputation that's yours.
The stripe-saas recipe makes the inbox speak billing. Subscription and invoice lookups, churn and billing-issue Skills, a revenue digest, and a webhook relay. Add your STRIPE_API_KEY and you're live. A B2B lead-qualification recipe layers on enrichment and scoring.
Questions
What you'll want to know.
- Can I deep-link into the Stripe dashboard like the Shopify card?
- Yes, that's a one-line Skill. Tinbox renders the billing context in the thread out of the box; you decide what links out and where. The click-through is yours to shape.
- How does the payment-failed alert work?
- Relay a Stripe webhook to Tinbox. The recipe ships the relay pattern with a signing-secret check: a few lines you deploy, and failed payments surface the moment they happen.
- Does transactional mail share the same domain and reputation?
- Yes. Resets, receipts, product updates, and support all send from your domain through one ledger with exactly-once delivery. One sender to warm up, one reputation to protect.
Why builders switch
What founders say.
“Churn used to hide in the inbox until it was too late. Now the account is in the thread and we catch it in one reply. It paid for itself on the first save.”

Sample testimonials: illustrative, pending real customer quotes.
The cheapest MRR is the MRR you keep.
The account renders in the thread, the save drafts itself, and every send runs off one ledger you own — so churn stops slipping past, and the inbox starts defending revenue. The last email tool you'll buy.
