Cooper Email

HTTP email API that gives each AI agent its own inbox

Email API for AI agents: one POST /api/v1/onboard request creates an API key and an inbox address; inbound mail arrives as signed webhooks; messages are full-text searchable across the account via SQLite FTS5. Also offers a hosted MCP server at /mcp, US phone numbers with SMS receiving on Starter and Pro plans, custom domains, and a human-in-the-loop owner updates/tasks flow. Operated by Avatar 8 LLC.
