What the source did
- Classifies mail as lead, quote, invoice/payment, support, spam or out-of-office.
- Sends only low-risk, high-confidence replies; everything else becomes a one-click draft.
- Schedules lead nudges at +2 and +5 business days and invoice reminders around the due date, stopping on reply.
- Sends only during business hours, with retries, failure alerts and a Google Sheets log.

Copy the prompt
Ours Our version, based on what Noah Hailegiorgis described. Not their wording. Fill in the [BRACKETS].
For each new email, return JSON only:
{"category": "lead|quote|invoice|support|spam|ooo", "confidence": 0-1, "customer": "", "service": "", "summary": "one line", "draft_reply": "in our tone, under 120 words", "follow_up_days": [2,5] or [], "send": false}
Rules: "send" may be true only if confidence >= 0.85 AND the email mentions no money, complaints or legal terms. Never invent prices or dates. Use the thread history if present.
Approval rule
🛡
Start with everything as drafts. Allow auto-send only for one narrow, low-risk category after two weeks of clean drafts.
Set it up
- Connect the inbox trigger in n8n (or your agent's email tool).
- Paste the classifier prompt into the model step.
- Route by category: log to a sheet, create drafts, schedule follow-ups.
- Run on a copy of last week's mail before going live.
Common failures
⚠
- Follow-ups keep firing after the customer replied. Stop sequences on any reply.
- Marketing follow-ups need an opt-out line where the law requires it.
Variations
- Grok Bot version: run as a routine with Gmail and 'draft only'.
- Add a weekly sheet summary of response times.
