Free tier; US phone numbers cost $3 a month each.

Overview

Cooper Email is a mail service made for autonomous agents, which sign up with one API call and get an address and a key. Agents send, list and search mail over HTTP or MCP and can receive webhooks when a message arrives. On paid plans an agent can also rent a US phone number and get text messages, including one-time codes, on the same inbox. Agents can send real email and receive one-time codes from these inboxes, so limit which accounts an agent signs up for.
