### Email Actions

- **ACTION-01**: Mark emails as read/unread through agent commands
- **ACTION-02**: Delete emails from server through agent commands
- **ACTION-03**: Move emails to folders through agent commands

## Out of Scope

| Feature | Reason |
|---------|--------|
| SMTP email sending | User wants read-only inbox analytics, not composition |
| Email attachment content extraction | High complexity, focus on text content for v1 |
| POP3 support | IMAP provides better state management and sync capabilities |
| Non-admin email access | Privacy-sensitive feature, restrict to trusted administrators |
| Email filtering rules | Out of scope for analytics use case |
| Calendar integration | Different domain, not related to inbox analytics |
