Frequently asked questions

How does AI Gmail Auto Labeler work?

The workflow automatically fetches unread emails from Gmail, loads your custom categories from Airtable, uses AI (DeepSeek LLM) to analyze and categorize each email, creates labels if needed, and applies them to your messages.

Can I use a different AI model instead of DeepSeek?

Yes! The workflow is designed to be LLM-agnostic. You can easily swap DeepSeek for OpenAI GPT, Claude, or any other compatible model by updating the API configuration.

What do I need to run this workflow?

You need: an n8n instance (self-hosted or cloud), a Gmail account with OAuth2 authentication, an Airtable account with Personal Access Token, and an API key for your chosen LLM provider.

How do I define my own categories?

Categories are defined in an Airtable table with simple columns: label name, sender domains, content description, and priority. Just add or edit rows to customize how your emails are sorted.

Will this work with Google Workspace?

Yes! The workflow works with both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. OAuth2 authentication is supported for both.

How often does the workflow run?

By default, it runs every hour. You can adjust the schedule in n8n or trigger it manually whenever you want.
