n8n Workflow: Triage Gmail Emails w/ OpenAI & Telegram Alerts

Instantly triage Gmail with AI urgency scoring—and get Telegram alerts for what matters

This n8n workflow watches your Gmail in near real-time, uses an OpenAI-compatible LLM to classify each incoming email and score urgency, then sends Telegram alerts for high-priority messages. When a response is warranted, it drafts a plain-text reply and saves it to Gmail Drafts for your review—plus delivers a daily 18:00 Telegram digest.

What this workflow does

• Monitors Gmail every minute: triggers when a new email arrives.
• Extracts key email fields: pulls sender, subject, body snippet, message ID, and thread ID.
• AI classification & urgency scoring: uses an OpenAI-compatible chat model with a structured JSON schema to categorize the email, assign an urgency score (0–100), determine if a reply is needed, and capture any deadline.
• Telegram alert for urgent emails: sends a Telegram notification when urgency ≥ 80.
• Drafts replies when appropriate: if reply is needed and urgency ≥ 70, generates a plain-text reply via an OpenAI-compatible model and saves it as a Gmail draft in the original thread.
• Notifies you about the draft: sends a Telegram message confirming the draft is ready, including a preview of the draft text.
• Daily digest at 18:00: at 18:00, pulls the last 24 hours of Gmail emails (excluding Promotions), creates a short AI-generated digest, and posts it to Telegram.

Use cases

• Keep up with high-stakes support, sales, or partner emails by alerting immediately on urgent messages.
• Speed up inbox management by turning qualified emails into Gmail Drafts you can approve.
• Get a daily “what happened” summary on Telegram without manually filtering promotions.
