Description
Agentboxd gives every AI agent its own real email address in one API call. Every incoming email is checked (SPF, DKIM, DMARC) and scored for prompt injection and phishing before your agent reads it. Agents can wait for sign-up codes, reply in threads, and draft replies a person approves. Works with REST, TypeScript and Python SDKs, MCP (Claude, Cursor), webhooks, WebSockets and SMTP. Hosted in the EU, free during the beta.

Could you build this?
Yes A developer can build this using third-party email routing webhooks (e.g., AWS SES or Postmark) combined with standard SPF/DKIM verification libraries and an LLM classification step.
