OpenEmail is a programmable email infrastructure platform that lets businesses run all their email on domains they already own, with unlimited mailboxes accessible via API, native webmail, or any standard email client. The platform provides full programmatic control over sending, receiving, storing, and routing email, making it as easy to provision email as it is to provision compute or payments with an API key.

Problem
Email remains one of the last core infrastructure primitives that businesses cannot fully own or control programmatically. Companies are forced to rent mailboxes from vendors, stitch together multiple services for simple operations, and lack the ability to provision email infrastructure with the same ease as payments, telephony, or compute.
Solution
OpenEmail provides a modern email engine that lets businesses run all their email on domains they already own, with unlimited mailboxes reachable via API, native webmail, or any standard email client. The platform makes everything programmable—anything you can do in an email client can be done over API, including sending, receiving, storing, and routing messages. Users point their DNS once to gain full control of production email, then create and destroy mailboxes freely for people, projects, agents, or customers. The service includes built-in webmail from day one, supports connection via IMAP or POP3 to existing clients like Apple Mail and Outlook, and allows forwarding entire domains or individual addresses to existing inboxes. Administration is handled through a user-friendly console, MCP, or CLI, making email infrastructure as simple as a few API calls.
