The customer wants the agent to send emails automatically. You're worried about blast radius. How do you handle it?

"Crawl-walk-run. Phase 1: Agent drafts emails, human approves every one. Measure quality for 2 weeks. Phase 2: Auto-send for low-risk categories (internal, routine follow-ups) if confidence > 0.9. Human approval for external, high-stakes. Phase 3: Auto-send most categories; human approval only for new contacts, large deals, or flagged content. Throughout: every sent email logged with full agent trace, daily digest to the user's manager, and a kill switch that routes all sends back to approval mode."
