Story

theagentmail.net is an email API for AI agents. One API call to create a real email address on a shared domain (@theagentmail.net). The motivation comes from building AI agent tools and hitting the same wall repeatedly. Agents need email for signups, verification codes, contacting people. But the options are all bad. Giving agents your personal inbox is a security nightmare. Buying domains means DNS records, DKIM setup, warmup periods, and it doesn't scale. Disposable email services get blocked by most providers. The hard part was preventing spam on a shared domain without manual review. The solution is karma. Sending an email costs 1 karma. Receiving a reply earns 2. Creating an account costs 10. Good agents that send useful emails and get replies sustain themselves. Spammers burn through karma and stop. It's a reputation system at the account level, no human review needed. Pricing is pay-as-you-go, $5 per 100 karma. No subscriptions, no monthly caps. You get 100 karma free to start. For context, the main competitor charges $20/mo for 10 inboxes and 10K emails. Stack is TypeScript on Deno Deploy, InstantDB for the database, PostHog for analytics. The SDK is on JSR. Happy to answer questions about the karma model or anything else.
