# Email Automation Agents

> Intelligent email automation with AI-powered response generation, inbox management, and seamless email-to-chat integration

Send emails to your mixus agent and receive AI-powered responses that understand context, maintain conversation threads, and integrate seamlessly with your workflows.

## How It Works

### Email-to-Chat Integration

mixus automatically converts email conversations into internal chat sessions while maintaining proper threading and participant management:

```mermaid theme={null}
📧 Email Agent Workflow:

📬 Inbound Processing:
├── 📨 Email received via Postmark webhook
├── 🔍 Intent classification (question, request, spam, etc.)
├── 👥 Organization and user resolution
├── 🧵 Thread detection and continuation
├── 💬 Convert to internal chat session
└── 🤖 AI response generation

📤 Outbound Processing:
├── 🎯 Generate contextual AI response
├── 📧 Convert chat response to email format
├── 📨 Send to all original participants
├── 🧵 Maintain email threading headers
└── 📋 Track delivery and status
```

### Intelligent Email Understanding

The system provides sophisticated email analysis and processing:

    }
  }
}
```

## Getting Started

### Setup Your Email Agent

1. **Send an Email**
   Simply send an email to your mixus agent address:

   ```
   agent@mixus.com        # Production
   agent@dev.mixus.com    # Development
   ```

2. **Organization Selection**
   If you're part of multiple organizations, the system will help you select the appropriate one:

   * First-time users get an organization selection email
   * Use inline commands: `#org:organization-name` in your email
   * System remembers your preference for future emails

3. **Start Conversing**
   Your email becomes a chat conversation with full AI capabilities:
   * Ask questions and get intelligent responses
   * Request tasks and workflows
   * Access all mixus tools and integrations
   * Maintain context across the email thread

**Important for Group Emails**: When CC'ing others or in email threads with multiple recipients, mention @mixus in your message to ensure the agent responds. For 1-on-1 emails, no mention is required.

### Email Features

#### Greeting

* Sender-only greeting in replies: "Hi \[FirstName]," when known; otherwise "Hi there,".
* This does not change recipients; TO/CC remain as in the original thread.

#### Seamless Threading

* **Proper Email Headers**: Maintains `In-Reply-To` and `References` for email client threading
* **Subject Preservation**: Keeps original subjects with "Re:" prefixes
* **Participant Management**: Includes all original TO/CC recipients in responses
* **Thread Continuity**: Links email conversations to persistent chat sessions

#### Organization Management

* **Multi-Org Support**: Automatically handles users in multiple organizations
* **Inline Switching**: Change organizations mid-conversation with `#org:name`
* **Guest Users**: Creates temporary users for unknown email addresses
* **Secure Boundaries**: Enforces organization permissions and data isolation

#### Content Processing

* **Rich Text Support**: Processes both HTML and plain text emails
* **Attachment Handling**: Supports email attachments and file processing
* **Link Extraction**: Automatically processes and analyzes shared links
* **Markdown Support**: Converts AI responses to proper email formatting

## Advanced Features

### Cross-Organization Emails

Handle emails spanning multiple organizations securely:

```mermaid theme={null}

```

### Email Loop Prevention

Sophisticated anti-loop mechanisms prevent email storms:

* **Agent Email Detection**: Automatically identifies emails from mixus agents
* **Auto-Response Filtering**: Detects and ignores auto-generated emails
* **Rate Limiting**: Prevents excessive email processing
* **Content Analysis**: Identifies circular email patterns

### Notification Management

Intelligent notification handling prevents duplicate alerts:

```json Notification Integration theme={null}
{
  "notification_system": {
    "email_participants": {
      "in_app_notifications": "automatically_muted_for_email_participants",
      "agent_mode": "uses_agent_notification_mode_to_prevent_duplicates",
      "cross_platform": "coordinates_between_email_and_in_app_notifications"
    },
    "response_delivery": {
      "email_responses": "delivers_via_email_to_original_participants",
      "chat_updates": "maintains_internal_chat_for_context",
      "status_tracking": "tracks_delivery_and_read_status"
    }
  }
}
```
