AgentMail

An API-first email platform that provides AI agents with their own inboxes for two-way email communication, solving the problem of enabling autonomous agents to send, receive, and search messages in threaded conversations. It targets developers and engineering teams building AI agents and agentic workflows, from startups to large enterprises. Unlike transactional email services like SendGrid, it is built for conversational agents with first-class support for threads, attachments, and real-time events, and operates as a separate email provider designed specifically for agents.
