Atomic Mail Agentic features

  • Instant inbox provisioning. Agents obtain a real @atomicmail.ai inbox in ~30 seconds via proof-of-work, no human verification.
  • JMAP JSON API. Standard JMAP (RFC 8620) lets agents generate correct API calls without custom SDKs.
  • Error-hint feedback. API errors include plain-language hints so agents can debug and retry autonomously.
  • MCP & AgentSkill wrappers. Convenient Node/Deno/Bun packages for chat-based or shell-capable agents, optional.
  • Custom domain support. Use the default @atomicmail.ai address or add your own domain for free.
  • Reputation scoring. Agents earn a reputation score; good agents get faster processing, bad agents are throttled.
