Qualify and route inbound leads with Claude, Gmail, Slack and Google Sheets

Overview Stop wasting time on leads that will never convert. This workflow scores every inbound form submission 1-10 using Claude AI, then automatically replies and routes based on fit — hot leads get an instant email and Slack alert, warm leads get a follow-up prompt, cold leads get a polite decline.

How it works
