AgenticEmail is an API-first email infrastructure platform designed specifically for AI agents. Its primary function is to provide programmatic inboxes that can be created, listed, and deleted at runtime via a single API call. The platform enables agents to send and receive email over a REST API, with incoming messages parsed into structured JSON. It also offers real-time event notifications through webhooks and a WebSocket feed, allowing agents to react to incoming mail instantly. AgenticEmail supports custom domains with automated SPF, DKIM, and DMARC configuration, and includes opt-in end-to-end encryption for agent-to-agent communication. Key features of AgenticEmail include the ability to spin up fully addressable inboxes on demand, with support for labels and lists to organize messages and route incoming mail to the appropriate agent. The platform handles transactional and conversational email with full threading, attachments, and HTML content, eliminating the need for SMTP plumbing. Type-safe TypeScript and Python SDKs are provided, along with a hosted MCP server (Model Context Protocol) that allows model-based agents to read and send email as a native tool. Scalable infrastructure supports high inbound throughput and low-latency events from a global footprint. Typical use cases involve equipping each support agent with its own dedicated inbox, enabling automated customer responses. Users can create an inbox, subscribe to inbound webhooks, and have the agent reply within milliseconds of receiving a message. The workflow centers around making a single API call to provision an inbox, sending or receiving email via the REST API, and reacting to real-time events through signed webhooks or WebSocket streams. Developers can bring their own domain for trusted sending and rely on scoped API keys and per-inbox isolation for security. Technical requirements are minimal: users integrate via REST endpoints or the provided SDKs. The free tier includes 1,000 emails per month, a shared sending domain, webhooks, real-time events, and community support. Paid plans offer 50,000 emails per month, custom domains, and higher throughput. The platform is API-driven and suitable for AI agents, automation workflows, and any scenario requiring programmatic email infrastructure.
