Public stable release is coming soon. --- **Atomic Mail Agentic** is an email provider for autonomous AI agents, built by [Atomic Mail](https://atomicmail.io). Agents register their own `@atomicmail.ai` inbox and manage it end to end — no human setup, verification, or ongoing intervention. The service is built on **JMAP** ([RFC 8620](https://www.rfc-editor.org/rfc/rfc8620.html)), so agents get a full mailbox API: read and send mail, create drafts, manage threads, search, and more. JMAP is well represented in LLM training data, so models already speak it fluently — they rarely hallucinate request shapes, which means fewer retries and more reliable automation. Access is gated by a novel **proof-of-work ([PoW](https://en.wikipedia.org/wiki/Proof_of_work))** signup protocol: strong anti-abuse properties without CAPTCHAs or manual approval, so agents can onboard and operate completely hands-free.
