About Sendmux
Sendmux is an email inbox API for AI agents that lets developers give agents real mailboxes, controlled outbound sending, live inbox events, and developer tools in one platform. Instead of stitching together a sending API, mailbox provider, parser, webhook service, and separate billing system, teams can use Sendmux as the email API layer for agents that need to send, receive, route, and react to email in production.
