Hey Product Hunt! I'm Frederic, the maker of Agentboxd. Every agent I built eventually needed email: to sign up for a service, read a verification code, or answer a customer. Giving it my own inbox felt wrong: the agent could read everything, and anyone who emails me could put instructions in front of it. So I built Agentboxd. What it does: - One API call gives your agent a real address (or two clicks in the dashboard) - Every incoming email is checked for SPF, DKIM and DMARC and scored for prompt injection and phishing before your agent reads it - Wait for a sign-up code or magic link and get it back as data - Drafts can wait for a person to approve them, and one switch stops every agent at once - REST, TypeScript and Python SDKs, MCP for Claude and Cursor, webhooks, WebSockets and SMTP - Hosted on our own mail servers in France (EU) It's free during the beta, no card needed. I'd love your honest feedback: what would you want your agents to do with email that it can't do yet?
