Summary ⤵️
Learn how I built a fully automated AI outreach system using n8n + GPT + Google Sheets + Gmail — no coding required. In this hands-on tutorial, I’ll show you how to build a workflow that reads a list of businesses from a Google Sheet, generates a personalized email for each one using Open AI GPT-5, and sends those emails automatically through Gmail.
This is perfect for:
• Cold outreach
• Launch announcements
• Following up with leads
• Partnership requests
The best part? It’s all free to replicate — I’ll walk you through every step, and you can download the template below.
