Overview
Agent Mail is an email infrastructure designed for AI agents, officially positioned as 'Email Inboxes for AI Agents', aiming to provide dedicated email addresses for agents and support programmatic sending and receiving of emails via API and SDK. It builds a complete email processing pipeline, covering inbox creation and management, conversation threads, attachment handling, real-time event push, custom domains, multi-tenancy, semantic search, and data extraction. Agent Mail offers Python and TypeScript SDKs and supports MCP Server integration, making it easy for developers to integrate email functionality into various AI applications. Since its launch, Agent Mail has delivered over 100 million emails and has been adopted by companies such as Browser Use, Pipedream, and Alchemy, becoming an important infrastructure in the field of AI agent email interaction.
Key Features
- Inboxes API Email Management: Create and manage multiple email addresses via API, supporting custom domains and multi-tenant architecture to meet the needs of applications of different scales.
- Conversation Threads and Replies: Automatically organize emails into conversation threads, support programmatic replies and forwarding, facilitating multi-turn conversation management for agents.
- Attachment Handling and Data Extraction: Support attachment upload, download, and parsing, with automatic extraction of key data from emails, such as invoice information and verification codes.
- Real-time Event Push: Push events such as new emails and status changes in real-time via Webhook or event streams, enabling agents to respond promptly.
- Semantic Search: Built-in semantic search capability allows querying email content based on natural language to quickly locate relevant information.
- Multi-language SDK and MCP Integration: Provides Python and TypeScript SDKs, and supports MCP Server integration, simplifying the development process and being compatible with mainstream AI frameworks.
Use Cases
- Browser automation agents extract verification codes from emails to complete account registration or login processes.
- Scheduling assistant agents manage meeting invitations, automatically parse time and location, and reply with confirmation.
- Financial automation agents parse invoice attachments, extract amounts, tax IDs, and other data, and enter them into systems.
- Customer service email intelligent routing, automatically classifying emails based on content and assigning them to appropriate processing flows.
- In multi-agent collaboration scenarios, agents communicate asynchronously and coordinate tasks through dedicated email addresses.
