Schedule (8 AM) or Manual trigger\n2. Gmail fetches the last 24h (Primary)\n3. Empty inbox \u2192 a friendly \"inbox zero\" Slack message\n4. Otherwise emails are bundled and triaged by the AI (validated JSON)\n5. A Block Kit digest is posted, grouped by category\n6. Urgent emails trigger a separate highlighted alert\n7. Each email is appended to a Google Sheet\n\n**How to use:** Connect the 4 credentials, pick your Slack channel + Sheet, run manually once to verify, then activate."
