AdvancedBot with human review ⚙️ Automation & agents
Classify and draft replies to incoming email.
1. Bot automation level
Bot with human review Agents act on real systems; review plans, approvals and results before trusting them.
2. Before you hand it to the bot
- Gather inputs: files, data samples, links and any templates.
- Set up access: connect only the apps/repos the agent needs, with least-privilege accounts.
- Context: tell the bot audience, purpose, constraints and examples of good output.
- Privacy check: remove personal, confidential or regulated data unless your plan/workspace is approved for it.
- Success criteria: write down what 'done' looks like (length, format, tests passing, fields filled).
3. Copy-paste prompts
Main prompt
Label incoming emails by type and draft replies for review.
Beginner-friendly
Label incoming emails by type and draft replies for review. I'm new to this: explain each step in plain words and ask me for anything you need before starting.
Check-your-work
Label incoming emails by type and draft replies for review. When you finish, list any assumptions you made, anything you're unsure about, and what I should double-check before using the result.
Free tiers that can handle this (verified): n8n. Others: check plan.

- Pick a bot/platform from the list below and confirm your plan includes the needed agent features.

- Paste the agent instructions below; include success criteria and where to stop for approval.
- Run once on a small sample and watch each step/log.
- Review the plan, actions and output; fix instructions and re-run.
