Inbox triage: classify and route email

Every 15 minutes, fetch the next unread email, classify it (urgent / billing / general) and route urgent ones to the on-call inbox with an auto-acknowledgement.

How it works

What it does

  • Runs on a 15-minute schedule, pulls the next unread inbox message via Gmail and marks it read.
  • ai.classify picks exactly one of urgent | billing | general (deterministic, temperature 0).
  • The Urgent? branch escalates urgent mail to the on-call address; everything else gets a polite auto-acknowledgement.

Setup

  • Choose the Gmail connection on Fetch next unread email (adjust label / query to narrow the mailbox).
  • Choose an AI provider connection on Classify email; edit the label set to match your queues.
  • Set the on-call address and a SendGrid / SMTP connection on both send nodes.
  • Publish — the scheduler registers the interval automatically.
