Draft email replies with AI but never auto-send

Skips automated senders, drafts a short reply into Gmail Drafts, and pings Slack for review. Sending stays out of the automation.

Prompt for your agent

Goal: Have replies ready to review without risking an AI email going out unchecked.
Setup: agents used in source: n8n; tools/MCPs stated: Gmail, Slack, Google Sheets.
Steps:
1. Filter out automated senders (no-reply, notifications, mailer-daemon, calendar invites, receipts).
2. Skip threads you already replied to or that already have a draft.
3. Have the AI draft a short, professional reply and save it to Gmail Drafts.
4. Send a Slack ping with a one-line reason that the draft is ready.
5. Optionally log thread id, draft id, recipient, subject and reason to a Google Sheet.
6. Never wire the send action into the workflow.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
