Workflow fit
Best when you want the same researched process to run consistently without rebuilding the node chain for every job.
Key features
- 9 n8n nodes from incoming Gmail message to a reviewable result
- Normalizes sender, subject, body, message ID and thread ID before AI processing
- Asks OpenAI for structured classification, confidence, summary and reply draft
- Creates Gmail drafts only when the message is classified as support
- Never auto-sends an AI-written customer response
- Separates skipped mail and draft failures into explicit outcomes
Setup instructions
1. Import the workflow JSON into n8n.
2. Add your Gmail credential to New Gmail message and Create Gmail draft. Use a test mailbox or a narrow label during setup.
3. Add your OpenAI credential to Classify and draft reply. Replace YOUR_SUPPORT_POLICY with concrete rules about refunds, delivery, privacy, account access and when no answer may be drafted.
4. Run the workflow with a support message, a newsletter and a message that requires escalation. Inspect classification, confidence, summary and draft text.
5. Confirm that support mail creates a draft in the original thread and non-support mail is skipped.
6. Check the failure outcome by temporarily using an invalid test setting, then restore it.
7. Activate the trigger only after the test label is clean. Review sender, facts, promises, tone and privacy before manually sending every draft. The workflow contains no automatic send step.
