Automatic Gmail Categorization and Labeling with AI

This n8n workflow automates Gmail inbox management by leveraging AI to prioritize and organize unread emails. Running every hour via a schedule trigger, it fetches unread messages from your inbox, extracts their content, and sends it to OpenAI for classification into one of four categories: Action (needs attention), Receipt (invoices/receipts), Informational (updates/news), or Spam (unwanted). Based on the AI's decision, it dynamically applies the corresponding Gmail label, moves spam to trash, and marks all processed emails as read, ensuring a clean and actionable inbox without manual intervention.

The benefits are immense for busy professionals overwhelmed by email volume: it saves hours of sorting time, reduces inbox clutter, flags urgent items instantly, and prevents important receipts from being overlooked. By automating prioritization, it boosts productivity, minimizes decision fatigue, and integrates seamlessly with self-hosted n8n using community nodes for Gmail OAuth and OpenAI API.

Ideal use cases include executives managing high-volume inboxes, small business owners tracking receipts, or anyone seeking an AI-driven personal assistant for email. Customize by tweaking the AI prompt for new categories like 'Meeting' or 'Newsletter', adjusting the schedule, or adding branches in the Switch node for advanced logic. Setup requires Gmail labels ('Action', 'Receipt', 'Informational') and credentials for Gmail and OpenAI.
