About EmailAgent.dev
EmailAgent.dev provides email addresses for AI agents. Developers provision an inbox for each agent persona through an API, then send and receive messages programmatically instead of building and running their own mail stack. The service is designed for agent workflows rather than for human mailbox clients.
Teams can attach custom domains with guided DNS mapping and managed sending infrastructure, issue API keys with scoped permissions for different tools and agents, and watch usage limits and metrics to keep volume predictable. The API follows OpenAPI, and official SDKs are available for TypeScript on npm and Python on PyPI, with documentation and a quickstart for the first inbox.
It is a hosted service with a free tier that provides one inbox on a shared emailagent.dev address, and a paid tier that adds more inboxes, a custom domain and a higher outbound volume. Upgrades are handled inside the app.
