Overview

End-to-end inbox automation that analyzes, sorts, and displays emails by category.

This AI agent automatically analyzes every new Gmail message with OpenRouter AI to determine its category, creates and applies color-coded labels, and sorts messages into Gmail’s sections using Multiple Inboxes. It uses a Google Sheet to manage category definitions and OpenRouter to power the AI routing. The result is a consistently organized inbox that highlights high-priority messages and reduces manual triage time.

FAQ

FAQ

Answers to common setup and usage questions.

No coding is required. The setup uses a no-code workflow in n8n and Google Sheets for category management. You only need to paste your OpenRouter API key and authorize Gmail and Google Sheets. The steps are guided and can be completed in under 15-20 minutes for most teams.

Yes. It works with standard Gmail accounts and leverages Gmail features like Labels and Multiple Inboxes. The setup assumes you can access Google Sheets and OpenRouter to power the AI routing. No enterprise prerequisites are required beyond the mentioned tools.

Absolutely. Create any categories in the Google Sheet and tailor the AI prompts to fit your business. The workflow reads these definitions and adjusts automatically. You can modify categories at any time and observe changes reflected in Gmail’s inbox views.

Labeling happens as part of the workflow run. If you schedule runs hourly, new messages will be categorized within that interval. You can increase frequency if near real-time processing is required, and initial labeling occurs within minutes of the first run.

Yes. You can set the workflow to run on a schedule (hourly or custom timing). This keeps classifications up-to-date without manual intervention. It’s also possible to trigger runs on new email arrival if your setup supports event-based triggers.

Every email is routed to a default uncategorized bucket or flagged for review. You can adjust the Google Sheet to add new categories or refine prompts so similar messages route correctly in the future. In practice, this reduces misses and helps you identify gaps in your taxonomy.

API keys are stored securely in the workflow configuration and not exposed in logs. Access is controlled through your OpenRouter account and your Google/Gmail permissions. You should rotate keys periodically and limit access to trusted team members.
