Inbox Manager: AI Email Automation with GPT, Calendar & Supabase

This workflow turns a cluttered inbox into a smart assistant using a Gmail trigger to monitor incoming emails. An AI classifier (powered by GPT) categorizes them into Sales, Client Communication, Reports, Billing, or Other, applying labels automatically. For new leads or priority messages, it intelligently routes to specialized agents.

The Calendar Agent integrates with Google Calendar to check availability and draft personalized replies offering consultation slots. The Knowledge Agent queries a Supabase vector database of your business knowledge to generate accurate FAQ responses. Both create Gmail draft replies, ensuring you're always in control while saving hours on routine tasks.

Ideal for marketing agencies, founders, and support teams handling inbound leads. Benefits include reduced email overload, faster lead response times, improved organization without a VA, and seamless notifications via Telegram. Adaptable for any business needing smarter email handling.
