🚀 Built an AI Gmail Agent in n8n (Auto-Triage + Drafts Replies to Save Hours Daily)

Hey everyone 👋

I’m sharing a free, open-source AI email agent workflow I built in n8n for Gmail users — my very first workflow that I made entirely myself, without using any templates.

What this workflow does

This n8n workflow acts as an AI-powered email triage assistant:

📥 Monitors incoming Gmail emails
🧠 Uses an AI agent to classify each email into exactly one label
🏷️ Automatically applies the correct Gmail label
✍️ Drafts AI-generated replies only when a response is required
🔄 Supports multiple AI models (easy to switch)

Default labels (fully customizable)

To respond
FYI
Comment
Notification
Meeting Update
Awaiting reply
Collab Request
Marketing
Cold Email

⚠️ You must create these labels in Gmail first — or update the system prompt to use your own.

Why I built this

This workflow is for people and businesses who receive a large number of emails every day and don’t have time to read and respond to each one manually.

Inbox overload wastes hours daily
Some businesses even hire people just to manage email
Reading, sorting, and drafting replies takes real focus and time

With this workflow, you simply activate it once, and the AI handles the triage and drafting automatically. You only review and send the important responses — everything else is organized for you.

Bonus workflow 🎁

I also included a bonus n8n workflow in the same repository that automatically creates Gmail labels for you.
