Gmail Triage to Google Calendar & Notion (OpenRouter LLM) n8n

Turn unread Gmail into calendar events and Notion tasks—automatically.

This Gmail Triage to Google Calendar & Notion (OpenRouter LLM) n8n workflow scans your Gmail inbox for unread messages, uses an OpenRouter-hosted LLM to classify and summarize each email, extracts an actionable task + due date, then creates a Google Calendar event and a Notion to-do item. Emails identified as spam are deleted to keep your inbox clean.

What this workflow does

• Checks every minute for newly arrived unread emails using an n8n Gmail trigger.
• Sends the sender, subject, and snippet to an OpenRouter LLM to classify the email into a single category.
• Deletes the email from Gmail if it’s classified as spam; otherwise it continues processing.
• Uses an OpenRouter LLM to generate a 2–3 sentence summary for a digest-style view.
• Uses another OpenRouter LLM step to extract an actionable task and an optional due date from the email content.
• Creates a Google Calendar event with the extracted action as the title and the summary as the description.
• Appends a Notion to-do block with the extracted action to your specified Notion page.

Use cases

• For SaaS operators: convert support, partnership, or sales emails into calendar reminders and Notion tasks.
• For automation engineers: a practical n8n template combining Gmail, LLM classification, and productivity tools.
• For busy teams: automatically summarize emails and ensure actionable items don’t get lost.
