Postfleet

Postfleet is an innovative email infrastructure designed specifically for AI agents, addressing the security concerns of handling inbound email data. It ensures every incoming message undergoes rigorous verification, including spam and virus screening, as well as prompt injection checks, before reaching the AI. This process guarantees that agents receive only safe, parsed, and comprehended messages, reducing the attack surface associated with raw inboxes. Outbound messaging is managed to be idempotent, with optional human approval, enhancing control and safety. Equipped with six MCP tools and a REST API, Postfleet is tailored for developers and organizations integrating AI agents into their workflows, providing a robust and secure communication layer.
