About AgentMail
AgentMail is an email inbox API created specifically for AI agents and autonomous systems. As agents become capable of handling more business processes, customer interactions, and operational tasks, they increasingly need a reliable way to communicate through email. AgentMail provides that capability through a developer-friendly API that makes inbox creation and management straightforward.
With AgentMail, you can provision real email inboxes programmatically and give agents the ability to send, receive, organize, and respond to messages. Each inbox behaves like a standard email account while remaining fully accessible through API calls. Agents can work with attachments, manage email threads, process incoming messages, and react to events in real time.
The platform also includes features that go beyond traditional email infrastructure. Semantic search helps agents locate relevant messages based on meaning and context, while built-in data extraction tools make it easier to convert email content into structured information that can be used in downstream workflows.
AgentMail supports Python, TypeScript, CLI, and cURL, making integration relatively simple across modern AI development environments. Compatibility with MCP further expands its usefulness for teams building agentic products and automation platforms.
Custom domain support allows you to deploy branded inboxes for agents, while real-time event streaming enables fast responses to incoming communications without relying on constant polling.
For teams building AI agents that need genuine two-way communication with customers, vendors, partners, or internal stakeholders, AgentMail provides a dedicated email infrastructure layer designed around autonomous workflows.

Real-time event streaming
Incoming email activity can trigger real-time events, allowing your agents to react immediately to new messages and reducing delays associated with traditional polling-based email integrations.
Custom domain inboxes
You can create agent inboxes using your own domains, helping maintain consistent branding and providing a more professional communication experience for external recipients.
Semantic search
Agents can search email content using meaning and context rather than exact keyword matches, making it easier to locate important information across large inboxes and lengthy conversations.
Data extraction capabilities
Built-in extraction features help your agents convert email content into structured data, reducing the amount of custom parsing logic required within automation pipelines and workflows.
SDK and MCP support
Official SDKs for Python and TypeScript, combined with MCP compatibility, help you integrate AgentMail into existing AI systems without significant implementation complexity.
