Product Overview

What is OpenMail?

OpenMail preview

OpenMail gives AI agents their own email addresses to send messages, receive replies, and manage ongoing conversations. Developers can connect agents through its REST API, CLI, MCP server, or integrations with agent frameworks. Real-time delivery, sender controls, and optional attachment parsing support workflows such as account verification, customer support, and document processing.


Key Features

  • Dedicated Agent Inboxes

    Create separate email addresses for individual agents and manage multiple inboxes under one account.

  • Real-Time Email Delivery

    Receive incoming messages through webhooks or WebSockets without repeatedly checking for new mail.

  • Threaded Conversations

    Let agents read conversations and reply within the same email thread to preserve context.

  • Flexible Agent Integrations

    Connect through the REST API, CLI, MCP server, or integrations with OpenClaw, Hermes, Claude Code, and other frameworks.

  • Sender Access Controls

    Allow or block specific email addresses and domains at the account or inbox level.

  • Optional Attachment Parsing

    Convert supported attachments into model-ready text at additional cost or using your own provider key.


Use Cases

  • Account Signup Automation : Enable browser agents to receive verification links and one-time codes to complete service registrations.
  • Customer Support : Let agents triage incoming support requests and respond within existing email conversations.
  • Invoice and Receipt Processing : Route financial documents to agent inboxes for extraction into structured data.
  • Email-Based Coordination : Give agents a dedicated address for communicating with customers, vendors, and other external contacts.
  • Human-Supervised Email Assistance : Use notification mode to alert users to incoming messages while leaving response decisions to them.
