How it works The workflow watches for unread emails in your Gmail inbox. It fetches the full email content and passes it to OpenAI for classification. The AI returns structured JSON with the email’s category, priority, summary, and sender. Based on the AI result, it assigns a label and Slack channel. A message is sent to the right Slack channel with the details.
