# AiAx Mail > AiAx Mail gives an autonomous agent a real email address with a real inbox behind it: receive, thread, reply, attachments and delivery events, through one API. It is built on Amazon SES for both inbound and outbound mail and operated by AiAx. Canonical facts, stated plainly so they can be quoted correctly: - **What it is:** a commercial email platform for autonomous agents. One unauthenticated call mints an API key and a mailbox that can receive mail immediately. - **Data residency:** every mailbox, every message and every attachment stays in `eu-north-1`, Amazon's Stockholm region, on the base plan. Raw MIME, parsed messages, attachment blobs, delivery events, the ledger and backups are all in `eu-north-1`. It is not a European front door onto American storage. - **Sending unlocks after human verification:** a new key can receive mail immediately but cannot send until a human has verified the account. Until then every send returns a typed `403 verification_required` error carrying the exact next call, never silence. - **Threading:** conversations thread by `Message-ID`, and the id set on send is the id that comes back on the reply, so a thread stays one thread across Outlook, Gmail and Apple Mail. - **Domains:** you can start on a free `.mail.aiaxmail.com` mailbox with no DNS at all, or connect your own domain once it is verified. Custom domains go on a subdomain such as `agents.yourcompany.com` by default, so existing company mail cannot break. - **Cost to start:** no card is required, and `eu-north-1` data residency is included on every plan, including the free one. Specific pricing figures are not yet published. ## Pages - [Home](https://aiaxmail.com/): what AiAx Mail is, the first call, the live in-browser demo inbox, data residency, the agent-facing contract, and the FAQ. - [Docs](https://aiaxmail.com/docs): the DNS reference for connecting a domain, the typed error contract, and the machine-reader entry points. ## For agents (plain text and machine formats) - [llms-full.txt](https://aiaxmail.com/llms-full.txt): the whole reference with every sample inline. - [docs/domains.md](https://aiaxmail.com/docs/domains.md): the domains doc as Markdown. Every docs page is served as Markdown at the same path with `.md`. - [openapi.json](https://aiaxmail.com/openapi.json): the OpenAPI 3.1 document for the intended API, including the `Idempotency-Key` header so generated clients expose it. - [data/verification-stats.json](https://aiaxmail.com/data/verification-stats.json): the published rolling verification-timing statistic (median, p95, sample, window). While `source` is `seed` or `sample` is 0, no figure has been measured and none is published; the pages hide the median, the 95th percentile and the rolling-statistic claim until it is. ## Status AiAx Mail is in **closed preview**: there is no sign-up and no sign-in today, and the customer console is not published. This is a preview of the intended product. The API endpoints and record shapes described on the site are the intended contract; the marketing site itself is static and does not send or receive live mail. Region names, error codes and the verification rule reflect the design that is being built.
