Built a full cold email automation system for myself — here's how it works

Just shipped this after weeks of building and testing.

It pulls leads from a Google Sheet, generates AI-personalized cold emails for each agent (name, city, company — all dynamic), and sends them automatically via Gmail.

If no reply, it follows up on Day 4 with a different angle. Still no reply, it sends a final breakup email on Day 11 with a Calendly link.

The thing that makes it special is human in the loop. It asks permission from me before sending follow-up emails. So I always know what is going on in the pipeline.

Every reply gets cleaned, classified by AI (Interested / Ambiguous / Not Interested), and routed to separate Slack channels to notify me instantly.

Everything logs back to Google Sheets automatically.

Built entirely on n8n — no paid email tools, no Zapier, no shortcuts.

Happy to answer questions about it.

Also let me know if there is any suggestions about it.
