Features

• Support for multiple email providers (Gmail, Outlook, Yahoo, etc.)
• HTML and plain text email support
• CC and BCC recipients

• Secure TLS/SSL connections

Setup Instructions

1. Configure Email Credentials

Create a configuration file email_config.json in your workspace:

{
  "smtp_server": "smtp.gmail.com",
  "smtp_port": 587,
  "username": "your-email@gmail.com",
  "password": "your-app-password",
  "sender_name": "OpenClaw Assistant",
  "use_tls": true,
  "use_ssl": false
}

2. For Gmail Users (Recommended)

1. Enable 2-factor authentication on your Google account
2. Generate an App Password:
   • Go to https://myaccount.google.com/security
   • Under "Signing in to Google," select "App passwords"
   • Generate a new app password for "Mail"
   • Use this 16-character password in your config

3. Alternative: Environment Variables

Set these environment variables instead of using a config file:

# Windows
set SMTP_SERVER=smtp.gmail.com
set SMTP_PORT=587
set EMAIL_USERNAME=your-email@gmail.com
set EMAIL_PASSWORD=your-app-password
set EMAIL_SENDER_NAME="OpenClaw Assistant"

# macOS/Linux
export SMTP_SERVER=smtp.gmail.com
export SMTP_PORT=587
export EMAIL_USERNAME=your-email@gmail.com
export EMAIL_PASSWORD=your-app-password
export EMAIL_SENDER_NAME="OpenClaw Assistant"

# Initialize with config file
sender = EmailSender("email_config.json")

# Send email with attachment
result = sender.send_email(
    to_email="recipient@example.com",
    subject="Important Document",
    body="Please review the attached document.",
    attachments=["document.pdf", "data.csv"]
)

    print(f"Error: {result['error']}")

Troubleshooting

Common Issues:

1. Authentication Failed

   • Verify your username and password
   • For Gmail: Use app password instead of regular password
   • Check if 2FA is enabled

2. Connection Refused

   • Verify SMTP server and port
   • Check firewall settings
   • Try different port (465 for SSL)

3. Attachment Too Large

   • Most providers limit attachments to 25MB
   • Consider compressing files or using cloud storage links

Security Notes

• Never commit email credentials to version control
• Use environment variables for production deployments
• Regularly rotate app passwords
• Consider using dedicated email accounts for automation
