Automated Stale User Re-Engagement: Supabase, Sheets & Gmail

This workflow automates user re-engagement by running daily to identify stale users (inactive for ~30 days) from a Supabase database via HTTP requests. It processes the data—editing fields, removing duplicates—and clears/updates a Google Sheet for comprehensive tracking and manual review.

Next, it crafts and dispatches personalized HTML emails through Gmail, tailored to bring users back with targeted messaging. Fully automated post-setup, it minimizes manual effort while maximizing retention rates for SaaS or app products.

Benefits include time savings on manual outreach, scalable personalization without coding, and actionable insights via Sheets. Ideal for marketing teams handling user churn in subscription services, e-commerce, or any user-based platform. Easily adaptable to other DBs/APIs by swapping the HTTP node.
