No installation required; works on macOS, Windows and Linux
Access unlimited email accounts simultaneously in one connection
Send emails with opt-in permission and approval workflow
Bounded blast radius: compromised agents can only spend remaining epoch allowance on whitelisted targets
Passkey root stays on user's device; cloud holds only scoped, expiring session keys
