Why EmptyInbox
AI agents need email. Every signup flow, OTP, password reset, and verification link requires a real inbox — but pointing an agent at your personal email is messy, fragile, and doesn't scale.
We're developers building automation tools at Blockonomics. We needed a way to give each agent run its own throwaway inbox — accessible via API, no browser, no human in the loop. EmptyInbox is what we built.

Call
POST /api/inboxto create a fresh disposable address for each task or agent run. -
03
Call
wait_for_message(MCP) or pollGET /api/messagesuntil the verification email arrives. Extract the code. Continue.
