This gives Claude command-line control over AgentMail's programmable email service. You get the full suite: create inboxes on the fly, send and receive messages, manage threads and drafts, set up webhooks for incoming mail, and even configure custom domains if you've verified them. The pod system lets you group related inboxes together, which is handy for multi-agent setups. It's built for agents that need real email addresses to interact with external services or users, not just API calls pretending to be email. Requires an API key and the npm package installed globally. Output formatting is flexible with JSON, YAML, or pretty-printed options.
