You are helping me build the following AI agent workflow.

## Goal
Email Management: Auto-Delete Marketing & AI Replies: Automatically deletes marketing emails while logging them to Google Sheets and drafts AI replies for genuine messages.

## Specification
- What it does: You instantly clear your inbox of marketing spam by having the agent delete those emails while logging them in Google Sheets for your records. For genuine messages that need a response, you get polite AI-drafted replies ready to send without lifting a finger.
- Trigger: Triggered by an event (Event · on new email via IMAP)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - Gmail: Reading, deleting, and replying to emails
  - Google Gemini: Classifying email type and generating replies
  - Google Sheets: Logging deleted and replied emails for auditing

## Known pitfalls, handle each one explicitly in your implementation
1. AI classification errors can delete important emails so always verify confidence scores or add a manual review step for low-confidence results.
2. Sensitive data exposure risks arise if PII is sent to external AI models so mask personal identifiers in the prompt payload before sending.

## Reference implementation
https://n8n.io/workflows/7551 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
