What this workflow does

This n8n workflow monitors Gmail, uses an AI Agent powered by OpenAI to classify message content, and automatically applies matching labels including Newsletter, Inquiry, Invoice, Proposal, Action Required, Follow-up Reminder, Task, Personal, Urgent, and Bank.

It is designed for professionals and teams who receive high email volumes and need consistent, AI-driven organization without manual sorting.

Who is this for?

Freelancers, small business owners, and support teams who rely on Gmail and want to reduce manual inbox management.

What problem it solves

Manually labeling and sorting high volumes of incoming emails wastes time and leads to missed priorities or disorganized inboxes.
