Auto-label Gmail emails using Gemini 2.5 Pro AI classification

AI-Powered Gmail Auto-Labeler

Automatically organize your Gmail inbox with seamless, dynamic AI classification! This workflow leverages Google Gemini’s latest model to continually sort new emails into your own custom Gmail labels—no manual intervention or tedious setup required.

🚀 What This Workflow Does

- Watches for Unread Emails: Continuously polls your Gmail inbox for new unread emails (polling interval can be changed as needed).

- Fetches All Available Labels: Dynamically syncs every custom & system label from your Gmail account—no hardcoded lists.

- AI-Based Classification: Each new email’s subject and snippet/body are sent to the Gemini 2.5 Pro AI, which analyzes content and recommends the best matching label(s) from your own label list (not made up!).

- Accurate Label Application: The workflow maps Gemini’s label name suggestions to the correct label IDs in Gmail and auto-applies one or more labels directly to each email.

- Self-Updating / No Maintenance: If you add/change Gmail labels, the workflow always uses the current label list. You don’t need to update any configuration or nodes (completely dynamic).
