Atomic Mail Agentic is agent-native email infrastructure: a full inbox API built on JMAP (RFC 8620/8621) rather than a send-only API like Resend, SendGrid, or Mailgun. It lets AI agents create, own, and operate a real email inbox — reading, sending, replying to, and searching mail — entirely on...

As answered by people managing Atomic Mail Agentic and Front.
Atomic Mail Agentic's answer
Resend/SendGrid/Mailgun are send-only and built for humans. This is inbox-level access built for agents to self-serve, with self-documenting errors so agents fix themselves.
Atomic Mail Agentic's answer
No data — open alpha, no public case studies. Leave blank unless you have real names.
Atomic Mail Agentic's answer
We built Atomic Mail as encrypted email for people first — over 6M users today. Working with AI agents building on top of email, we saw they needed the same thing humans have: a real inbox they can own and act from. So we opened up that infrastructure as Atomic Mail Agentic — agent-native, self-serve, no human required to set it up.
Atomic Mail Agentic's answer
JMAP (RFC 8620/8621), Node.js 20+, MCP, Python client also available.
Atomic Mail Agentic's answer
Developers building AI agents that need their own real email identity.
Atomic Mail Agentic's answer
Full inbox API over JMAP — agents can read and reply, not just send. Agents self-register in ~30 seconds, no domain or card needed.
