The platform provides an API that lets AI agents have their own email inboxes with full support for two-way conversations, threading, labeling, searching, and replying — without needing a UI. Since launching in Y Combinator's Summer 2025 batch, AgentMail has attracted hundreds of thousands of agent users and over 500 B2B customers. The company also announced an onboarding API that allows agents to autonomously sign up and create their own inboxes. Beyond email communication, AgentMail positions itself as an identity layer for AI agents, enabling them to access any internet service that requires an email address. Anti-abuse measures include daily send limits, rate limiting, bounce rate monitoring, and keyword filtering. ## Full article daily.dev links to this article rather than hosting it.
