What this workflow does

This workflow runs every day on a schedule and processes your entire old client database automatically. For each client, it checks whether they've replied to any of your emails in the last 30 days. If they have, it pauses automation and flags that client for manual reply. If they haven't, it fetches their last 10 email conversations, pulls scenario-based AI prompts and follow-up message direction templates from your Google Sheet, feeds everything into Claude 3.7 Sonnet to draft a highly personalized re-engagement email, sends it via Gmail, and updates your tracking sheet — all without any manual intervention.

Perfect for agencies and freelancers who have past clients sitting idle in their database and want a fully automated, intelligent outreach system that feels human, not spammy.
