Show HN: Pidgeon – Email inboxes for AI agents

Pidgeon is a product that gives AI agents their own email inboxes, created with a single API call, so they can send mail at volume, hold threaded conversations, manage calendars, extract details from attachments, and hand threads off to humans. It includes a firewall that reads every inbound message and flags hidden instructions before the agent sees a clean copy, plus EU data residency, scoped keys, and a 90-day audit trail. A TypeScript SDK is available via npm, and signup is free to start.
