Automatic Email Categorization & Labeling in Zoho Mail with GPT-4o-mini

This n8n workflow automates email categorization in Zoho Mail by leveraging GPT-4o-mini for intelligent text classification. Upon receiving a new email, it fetches existing labels (e.g., Support, Billing, HR), analyzes the subject and body content with AI, and applies the most relevant label automatically. This ensures structured inboxes, reduces manual sorting, and prevents important emails from being overlooked.

Key benefits include significant time savings for busy professionals, seamless routing of customer support to teams, organized billing communications, and efficient HR handling. It's ideal for businesses dealing with high email volumes, such as travel agencies managing accommodation bookings, inquiries, and reservations under categories like Travel > Accommodation.

The workflow supports regional Zoho domains (com, eu, in) and requires pre-existing labels. Test with sample emails before full deployment to optimize AI prompts and minimize costs from AI providers like OpenRouter. Use cases extend to e-commerce order confirmations, vendor communications, and client feedback organization.

Setup involves configuring Zoho OAuth credentials and ensuring labels exist. Advanced logic handles label mapping (display name to ID), making it robust for production use.
