AI Email Triage & Drafting Agent for Gmail Automation

Transform your Gmail inbox from a chaotic mess into an organized, AI-powered productivity machine. This intelligent email triage workflow automatically categorizes incoming messages, generates draft replies, and ensures nothing important slips through the cracks while keeping you in control of every response.

What this workflow does

This Gmail automation workflow polls your inbox every minute for new unread emails and processes them through an intelligent AI triage system. Using Google's Gemini 2.5 Pro AI Agent, it reads each email and full thread context, checks your Google Calendar for availability, then automatically classifies messages into six strategic categories: Urgent, Reply, Read, Notification, Newsletter, and Invoice.

For emails requiring responses (Urgent or Reply categories), the AI drafts professional HTML replies complete with your signature and saves them as Gmail drafts. All processed emails are automatically labeled according to their category and marked as unread, ensuring they surface for your final human review before any replies are sent.

Use cases

• Small business owners managing client communications while focusing on core business activities
• Consultants and freelancers handling high-volume prospect and client email workflows
• Customer service teams needing intelligent email routing and draft response generation
• Busy professionals who want email organization without losing personal oversight of outbound communications
