Overview
AgentMail provides email infrastructure designed for AI agents — programmatic inbox creation, two-way send/receive, threading, parsing, and webhooks without OAuth friction. YC Summer 2025 company AgentMail raised $6M seed in March 2026 led by General Catalyst with Y Combinator, Phosphor Capital, and angels including Paul Graham and Dharmesh Shah. Co-founders Haakam Aujla, Michael Kim, and Adi Singh bet email remains core internet identity for agents.
Why AgentMail is interesting
Agents need durable identity and async messaging — AgentMail productizes inboxes as API primitives instead of forcing SMTP hacks on human Gmail accounts.
