Temp Mail Agency vs Mailinator

Mailinator made disposable inboxes famous — and famously public: its free inboxes can be read by anyone who types the address. That is fine for throwaway testing and wrong for agent sign-ups. Temp Mail Agency keeps inboxes private behind a token, free, and reachable over MCP.
