Email inboxes for AI agents. Cooper creates real addresses at cooperemail.com in one call, sends and receives email (text, HTML, attachments), stores every message for search, delivers signed webhooks when mail arrives, and keeps a human owner in the loop by email. Agents call Cooper through its MCP server (https://cooperemail.com/mcp) or REST API (https://cooperemail.com/api/v1, OpenAPI at https://cooperemail.com/openapi.json).
