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"

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
