ai provides email infrastructure designed specifically for AI agents, offering a self-serve API that enables integration of email functionality into agent-based applications. The platform is positioned to allow developers to assign a working email address to their AI agents with minimal code, while equipping each inbound message with parsing, identity, and reputation features. The tool is intended for use by those building or operating AI agents that require email capabilities.

Key features include a reputation graph, dedicated IP architecture, and a Model Context Protocol (MCP) server. ai processes every inbound email by performing a prompt-injection scan, assigning an injection_score, and evaluating sender_reputation. There is an opt-in classification feature that can extract intent and entities from incoming messages. The structured reply events feature ensures that inbound emails are parsed and handed to the user’s code in a structured format. The built-in injection scanning system uses a six-category prompt-injection scanner, flagging and quarantining events with a score above a specified threshold.

The platform is delivered as an API service, with documentation and API references available for integration. No information is provided about licensing terms or company details beyond the existence of a company section on the site.

ai is positioned within the class of email infrastructure tools tailored for AI agents, focusing on secure, structured, and reputation-aware email handling. Its architecture and feature set are designed to address the unique challenges of integrating email with automated agent workflows.
