In this build, I put together an n8n workflow that automatically follows up with GoHighLevel (GHL) contacts who’ve gone quiet. We start the automation two ways: a manual trigger when you want to run it on demand, and a scheduled trigger (I’d usually do daily at a business hour like 9am, with the correct timezone set in n8n). From there, we pull inactive contacts from GHL, add basic error handling, and run filtering logic so we’re only targeting the right people. Then I send a personalized follow-up email through Gmail, wait 24 hours, and pull the email thread to see if the lead replied. Instead of guessing, I branch the workflow based on whether the message contains “yes” or “no” (with ignore-case so we don’t miss variants), plus a fallback path for anything else. If it’s a “yes,” I run sentiment analysis on the response (I used Anthropic in the AI node) and fire a Slack alert to the sales team so a human can take over fast. Finally, I log outcomes to Google Sheets and show how you can optionally update the contact back in GoHighLevel (tags/custom fields) once you’ve collected enough data to know what you want to track.
