The ticket is logged to Google Sheets and marked as read (so it is never processed twice). A Switch then routes each email by priority: high-priority tickets get an urgent draft plus an on-call Slack escalation, medium tickets get a standard draft, low tickets get an acknowledgement draft, and anything unclassified is flagged for manual review. If the AI call fails, the email is reported to Slack instead of being lost.\n\n### Setup\n1. Connect Gmail, Google Gemini (PaLM) API, Google Sheets and Slack.\n2. In **Set Configuration**, set your brand, guidelines and urgent keywords.\n3. Point **Log Ticket to Sheet** at your spreadsheet and pick your Slack channels.\n\n### Customization tips\nAdd categories, change the escalation channel, or auto-send low-priority acknowledgements."
