Unified Email Intelligence Hub
Automate your inbox with AI-powered classification, prioritization, and draft reply generation.
Workflow Setup Guide
Overview
This workflow connects your Gmail and Outlook accounts to automatically process, analyze, and organize every incoming email. Using AI, it classifies emails by type and urgency, generates professional draft replies, applies labels, and alerts you via Slack when attention is needed — all without ever sending anything automatically.
Core philosophy: Human oversight at every step. All AI-generated replies become drafts for you to review before sending.
What This Workflow Does
| Step | Action |
|---|---|
| 1. Fetch | Retrieves up to 20 unread emails from Gmail and 20 from Outlook per run |
| 2. Normalize | Combines both sources into a unified email format |
| 3. Analyze | AI classifies each email (urgent / important / reply_needed / personal / newsletter / automated / spam) and assigns priority (1–10) |
| 4. Summarize | Generates a 2–3 sentence AI summary of each email's content |
| 5. Draft | Creates draft replies in Gmail or Outlook for emails marked as reply_needed |
| 6. Label | Applies Gmail labels (IMPORTANT, STARRED, CATEGORY_PROMOTIONS, etc.) |
| 7. Alert | Posts to Slack when priority ≥ 7 or marked urgent |
| 8. Log | Records every processed email to Google Sheets |
| 9. Visualize | Displays real-time analytics on an interactive dashboard |
