Gmail Triage with Gemini: Auto-Label & Alerts via Telegram

Turn every incoming Gmail email into an organized, actionable task—automatically. This n8n workflow uses Google Gemini to classify, summarize, and flag urgency, then applies Gmail labels, optionally drafts replies, logs invoice details to Google Sheets, and sends instant Telegram alerts.

What this workflow does

• Watches your Gmail inbox every 5 minutes for new messages (excluding Promotions, Social, and your own emails).
• Fetches full email content, formats it into a clean prompt, and sends it to Google Gemini to return a JSON output containing: category, summary, urgency flag, optional reply text, and optional invoice fields.
• Ensures Gmail labels exist (e.g., AI/Clients or AI/Invoices) and applies the correct label to each classified email.
• Creates reply drafts (optional) when Gemini indicates a response is needed—drafting a reply in the same thread addressed to the sender.
• Tracks invoices (optional): if an email is classified as an invoice and a Google Sheets document ID is provided, the workflow appends extracted invoice fields plus a link to the email in your invoice tracker.
• Sends urgent alerts via Telegram when marked urgent and a Telegram chat ID is provided, including sender, subject, and a one-line summary.
• Logs everything in an n8n Data Table: received time, sender, subject, category, urgency, summary, and whether a draft or invoice entry was created.

Use cases

• SaaS operators who want automated Gmail categorization and fast escalation for urgent messages.
• Automation engineers building Gemini-powered triage to reduce manual inbox work.
• Teams that need invoice extraction and a running ledger in Google Sheets.
