AgentMail

AgentMail is the email inbox API purpose-built for AI agents. It provides agents with their own dedicated email inboxes — complete with threads, attachments, real-time events, and custom domains — accessible entirely via API. Backed by Y Combinator and SOC 2 Type II certified, AgentMail is designed to scale from individual developers to enterprise deployments.

• Inboxes API — Create, manage, and operate email inboxes programmatically via REST API; get started by installing the Python or TypeScript SDK and calling client.inboxes.create().
• Threads & Replies — Full thread management so agents can follow conversation context across multiple messages.
• Attachments — Send and receive file attachments within agent-managed inboxes.
• Realtime Events — Webhook endpoints and WebSocket support deliver live inbox events to your agent pipelines.
• Custom Domains — Assign custom sending and receiving domains to agent inboxes for branded or white-label deployments.
• SDKs & MCP Server — Official Python and TypeScript SDKs plus a Model Context Protocol (MCP) server for direct integration with LLM agent frameworks.
• Semantic Search — Search inbox content semantically to help agents retrieve relevant messages.
• Data Extraction — Extract structured data from incoming emails for downstream agent processing.
• Deliverability — DKIM, SPF, DMARC support, optimized shared IPs, dedicated IPs (Startup+), and suppression lists ensure reliable email delivery.
• Security & Compliance — SOC 2 Type II certified, multi-factor auth, signed webhooks, OIDC/SAML SSO (Enterprise), and team-based access controls.
• Enterprise Options — White-label platform, EU region cloud, bring-your-own cloud deployment, and custom volume pricing available for large-scale needs.
