Automatic Gmail Email Labeling with OpenAI and Gmail API

This workflow automates the categorization of incoming Gmail emails by polling for new messages every 5 minutes via the Gmail Trigger node. It fetches existing labels, retrieves full email content, and uses OpenAI's Chat model to intelligently analyze and suggest the most relevant label. If no suitable label exists, it dynamically creates one and applies it, ensuring seamless organization.

Key benefits include significant time savings on manual sorting, reduced inbox clutter by handling ads and irrelevant emails, and adaptive labeling that evolves with email patterns. The integration of Memory Buffer maintains context across processings, while a Wait node prevents overload.

Ideal use cases: Procurement teams in commerce managing supplier emails, sales handling inquiries, or any business needing automated email triage. Prerequisites are Gmail OAuth2 and OpenAI API keys. With 8 nodes including multiple Gmail API calls and AI, it offers robust, scalable automation.
