Free; managed Cloud in preview.
MachineMail is an email API for AI agents: free inboxes on demand, a hosted MCP server and webhooks, and a trust report on every inbound message that strips hidden instructions and tells the agent whether the sender can be believed. Its /v0 API is compatible with AgentMail's.
