Capture, score and route Gmail leads with Groq Llama 3.3, Supabase and Slack

How it works
This workflow captures incoming leads from Gmail, validates and stores them in Supabase, then uses AI to score and classify each lead. Based on the classification, leads are automatically routed to the appropriate Slack channel. It runs continuously with a wait cycle to process new and updated leads. The result is a fully automated lead qualification and routing system.
