AgentMail

What is AgentMail?

AgentMail is an API-first email platform specifically designed for building AI agents that can communicate via email. Unlike traditional email APIs focused on one-way notifications, AgentMail enables two-way conversations, allowing AI agents to read, understand, and reply to emails within threads just like humans. It serves as the email infrastructure layer for AI applications, providing dedicated inboxes that agents can operate programmatically.

Main Features

1. Inboxes API: Create, manage, and operate email inboxes entirely via RESTful API.

2. Threads and Replies: Maintain conversational email threads with proper threading support.

3. Attachments: Handle file attachments in both incoming and outgoing emails.

4. Real-time Events: Receive instant notifications via webhooks and websockets for new emails.

5. Custom Domains: Use your own domains for professional email addresses.

6. SDKs and MCP: Official SDKs for Python, TypeScript, and cURL with Model Context Protocol support.

7. Semantic Search: Advanced search capabilities within email content.

8. Data Extraction: Automatically parse and extract information from emails and attachments.

9. Instant Provisioning: Create new inboxes in milliseconds with one API call.

10. Enterprise Reliability: Built on redundant infrastructure across multiple regions.

Use Cases

1. Browser Agents: Extract 2FA/OTP codes from emails to enable automated service sign-ups.

2. Scheduling Assistants: Let AI agents manage calendars, schedule meetings, and send summaries.

3. Document Processing: Automatically parse invoices, receipts, and other attachments from emails.

4. Customer Service: Ingest support emails and intelligently route them to appropriate handlers.

5. AI Agent Communication: Enable any AI agent to communicate with users via email channels.

6. Automated Workflows: Power automated email responses and interactions within business processes.

Supported Languages

1. English (primary interface and documentation)

2. The platform supports email content in any language since it's API-based

3. SDKs available for Python and TypeScript programming languages
