Features

The full retention stack, in one focused tool

Risk scoring, win-back sequences, reply tracking, and a Monday briefing — all working together so saves don’t slip through the cracks.

87

AI Risk Scoring

GPT-4o analyzes payment patterns, usage signals, and subscription history to score every customer’s churn risk.

Per-customer AI

Emails In Your Voice

Tell Backstop your business type, what you sell, and what to never say. Every email reads like you wrote it — not a SaaS template.

Anti-jargon AI

One-Click Stripe Sync

OAuth into Stripe in 60 seconds. Customers, subscriptions, invoices, and payment history sync continuously — no API keys, no manual exports.

OAuth — no API keys

Review Queue + Autopilot

Approve, edit, or regenerate every email before it sends — or flip to autopilot for hands-off retention. Switch modes anytime.

Monday Briefing

Every Monday morning, a one-page email: who’s newly at risk, who’s saved, what changed, what to do this week. No dashboard required.

Reply Tracking + Inbox

When customers reply, Backstop catches it, threads it to their profile, and shows you the conversation. Your customer’s response, in context.

Two-way email

Multi-Step Sequences

Win-back, dunning, onboarding, post-cancel — multi-touch sequences that pause when a customer replies and resume when they don’t. No duplicate sends, ever.

6 sequences built-in

Slack Alerts

Get pinged the moment a high-MRR customer hits critical risk, replies to a sequence, or cancels. Route to the right channel — founder, success, or revops.

Real-time pings

Automations Engine

Build your own rules. If risk > 80 and MRR > $100, send win-back + ping #revenue. No-code triggers that fire on every customer event.

SubjectHey Sarah — quick one

Hey Sarah,

Noticed you haven’t opened a Mariners Wheelhouse post in about three weeks — right around when your card got declined and re-ran. Figured I’d check in instead of just letting the renewal lapse.

Is the coverage falling flat? Too much trade chatter, not enough prospect stuff, something else? I read every reply, so be honest — I’d rather fix it than lose you.

If you’re just stretched on the budget right now, hit reply and I’ll sort something out. Otherwise, talk soon.

— Casey
