Products that do what Agent.email – sign up via curl, claim with a human OTP does
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 built MailCat because my AI agents kept getting stuck at "please verify your email." The key insight: if your AI agent can read documentation, it can set itself up. Just paste this into Claude Code, OpenClaw, or any AI agent: "Read https://mailcat.ai/skill.md and set up a MailCat mailbox for yourself. Save the token securely." That's it. Your agent reads the skill.md, creates a mailbox via API, and handles email verification autonomously from there. What it does: - Instant mailbox creation via API - Verification codes auto-extracted from emails - 1-hour retention…
