Sendmux is one workspace and API to send, receive, route, and monitor email, built for products and AI agents. Most email platforms stop at sending. Sendmux gives your app or agent a real inbox that can send mail, receive it, hold it, reply, and search across threads, all from the same place. Where it stands apart is how it treats AI agents. An agent can self-register for its own constrained mailbox and then invite you to approve it. Until you say yes, it can read and receive but cannot send a single message. Human approval is the default, not an add-on, so you can hand an agent its own email address without handing over your sending reputation. Under the hood you get transactional sending for single or batch email, real mailboxes on your own verified domain or the shared myagent.mx domain, and full inbox access to read, triage, reply, and sync messages. Delivery logs and metrics are searchable and exportable to CSV, webhooks are signed for delivery and inbound events, and API keys are scoped separately for sending, mailbox, and management. You connect however you work: hosted MCP with OAuth, a CLI, or SDKs for Python, Go, Ruby, PHP, and TypeScript. Each team starts with 50 mailboxes. It fits developers who want transactional sending plus a programmable inbox in one API, and teams building AI agents that need to send and receive email safely. Give an agent its own inbox, keep a human in the loop on every send, and see exactly what went out. That's Sendmux.
