AgentMail

About

AgentMail is an API-first email platform purpose-built for AI agents. While traditional email services are designed for humans clicking through inboxes, AgentMail gives AI agents their own email addresses with full two-way conversation capabilities. Backed by Y Combinator and freshly funded with $6M from General Catalyst, AgentMail lets developers create, manage, and operate email inboxes entirely via API — supporting threading, parsing, labeling, searching, and replying. Whether you're building a customer service agent, a browser automation workflow, or an AI sales rep, AgentMail enables your agent to communicate over email just like a human would. The platform is SOC 2 compliant and trusted by AI companies building production-grade agent systems.
