Reduce Customer Churn with Claude Scoring + Gmail Save Emails (n8n)

Catch at-risk customers before they cancel—then email them automatically with Claude scoring

This n8n workflow helps you reduce customer churn by ingesting customer health signals via a Webhook, using Claude to score churn risk (0–100), and automatically sending a personalized “save-play” email through Gmail to customers who are slipping away.

What this workflow does

• Receives customer health signals through a Webhook (one customer per call) in JSON, including signals like last login, usage change, email open rate, support sentiment, days to renewal, open tickets, and plan value.
• Normalizes the payload safely with a Set node so missing fields won’t break the run.
• Scores churn risk with Claude (Anthropic Chat Model) using structured output: a churn score from 0–100, a risk tier (RED / YELLOW / GREEN), the top contributing signals, and a draft personalized HTML save-play email.
• Creates one clean health record by flattening AI output and original data (Shape node).
• Logs every account to a data table for tracking and reporting (mapped columns include customer_id, churn_score, risk_tier, action_taken, logged_at, and more).
• Routes actions by risk tier with a Switch:
  • RED: triggers a save-play email
  • YELLOW: sends a lighter nurture email
  • GREEN: logs and monitors
• Email reliability: Gmail email nodes retry automatically 3×.

Use cases

• SaaS operators: identify customers with worsening engagement (e.g., lower open rate, more open tickets) before renewal.
• Customer success teams: trigger targeted save-play outreach for RED accounts while keeping GREEN customers on watch.
• Automation engineers: maintain an audit trail by logging every churn evaluation to a data table.
