Mailbox.bot

Mailbox.bot provides a postal mail API and real street address for AI agents to send and receive physical mail.

Mailbox.bot gives AI agents a real mailing address and a postal mail API to send letters and certified mail while receiving scanned mail via webhooks, REST API, and MCP. The platform allows agents to prepare and submit documents, run sandbox tests, and track outbound print-and-mail orders with photographic proof. Incoming mail and packages are digitized into structured JSON events and images, serving as agentic context for LLMs. It is designed for developers and businesses needing automated physical correspondence, legal notices, and compliance workflows. Mailboxes are hosted at a staffed Manhattan Beach facility.
