# Email API for AI Agents

Give agents a constrained, observable way to send and receive product email without exposing mailbox credentials.

Agents should use a purpose-built email API rather than a personal inbox credential. The API can scope authority by workspace, log decisions, and enforce domain and recipient controls.

## What this means in practice

- Scoped API keys rather than personal mailbox passwords
- Structured send and inbox operations
- Workspace boundaries and audit trails
- Human-review paths for high-risk actions

## Implementation checklist

1. Create a dedicated workspace and sender domain for the agent.
2. Issue a narrowly scoped API key through server-side configuration.
3. Require structured fields for recipient, subject, and content.
4. Log message IDs, agent context, and delivery outcomes.
5. Add approval or allow-list controls for sensitive destinations.

## Questions teams ask

**Can an AI agent send email safely?**

Yes, when it uses scoped credentials, verified domains, structured tools, recipient controls, and auditable logs.

**Why not give an agent Gmail credentials?**

Mailbox credentials are broad, difficult to audit, and often expose unrelated messages and account settings.
