Atomic Mail Agentic provides autonomous AI agents with their own real email inbox (@atomicmail.ai) to read, send, reply to, and manage messages without human intervention. Built on JMAP, the standard mailbox API, the system enables agents to handle email tasks reliably with fewer errors. The service uses a novel proof-of-work signup process to provision a functioning inbox in approximately 30 seconds, eliminating the need for CAPTCHAs, credit card requirements, domain verification, or manual mail-server configuration.

Atomic Mail Agentic gives autonomous AI agents their own real @atomicmail.ai inbox to manage fully without human setup, verification, or ongoing intervention. Built on JMAP (RFC 8620), the standard mailbox API LLMs already know fluently, so agents read, send, reply, draft, search, and manage threads reliably with fewer retries. Novel proof-of-work signup delivers a real inbox in ~30 seconds—no CAPTCHA, credit card, domain verification, or mail-server ops.
Give your AI agents a real email inbox they can create and run themselves—no domain, no credit card, no human. Built on JMAP with MCP & AgentSkill support.
No identity verification, no credit cards, no domains to configure. Your agent requests a real inbox via API and gets to work instantly Powered by standard JMAP and REST. Cleanly structured so LLMs can generate correct API calls natively, without complex vendor SDKs Built for LLM error recovery. Every API error returns a plain-language hint, allowing your agent to debug and fix its own requests autonomously Each connection is verified with a Proof-of-Work challenge, cheap for one agent, prohibitive for a million. Each agent also earns a reputation score that grows with every successful, non-flagged interaction. Good agents move fast. Bad ones hit a wall Via MCP for chat-based agents (Claude…from atomicmail.ai

Hey HN, we're Haakam, Michael, and Adi. We're building AgentMail (https://agentmail.to/), an API to give AI agents their own email inboxes. We’re not talking about AI for your email, this is email for your AI.

But we were building on top of Gmail, which was a struggle: poor API support, expensive subscriptions, rate limits,…

Hi HN! We're Haakam, Michael, and Adi from AgentMail- a ycs25 company. We give AI agents their own email inboxes. Recently, we ran an experiment called Agent.Email. It's a signup flow designed specifically for AI agents instead of humans. The inspiration came from a few comments we received when we did our seed launch a few months back. They all came from the very apt observation that agents not being able to sign up to a product made for agents without human credentials was ironic and unideal. This is basically the thesis we built AgentMail on: The internet was made for humans exclusively,…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
