The workflow pulls inactive contacts from GHL, uses AI to generate personalized follow-up emails, waits 24 hours to check for replies, runs sentiment analysis on responses, and uses a GoHighLevel Slack integration to fire alerts directly to your sales team. It also logs everything to Google Sheets automatically. Whether you're running an agency or managing your own sales pipeline, this is the kind of automation that keeps leads warm without any manual effort.
