What is Gmail Sender Skill?
The Gmail Sender Skill is a streamlined automation tool designed for developers and power users who need a reliable way to dispatch emails directly from their Openclaw Skills environment. By leveraging the Python standard library and Google secure App Passwords, it provides a dependency-free method to integrate email notifications into scripts, workflows, and cron jobs.
This skill serves as a foundational component for building complex Openclaw Skills that require outbound communication capabilities. It ensures that status updates, system alerts, and automated reports reach their destination without the overhead of external third-party API integrations, keeping your automation stack lean and efficient.
Gmail Sender Skill Use Cases
- Automated server health alerts and high CPU usage notifications.
- Sending scheduled morning reports or daily summaries via cron jobs.
- Integrating email dispatch functionality into custom Openclaw Skills workflows.
- Notifying administrators of successful script completions or failures in long-running processes.
How Gmail Sender Skill Works
- The user configures their Google Account with 2-Factor Authentication and generates a dedicated 16-character App Password.
- Environment variables are set to securely store credentials locally without hardcoding them into the skill scripts.
- The Gmail Sender script establishes a secure SMTP connection to Google servers using the provided environment variables.
- The skill accepts command-line arguments for the recipient email address, subject line, and message body.
- It transmits the email and provides feedback or error codes based on the SMTP server response.
Gmail Sender Skill Setup
- Enable 2-Factor Authentication on your Google Account and generate a 16-character App Password.
- Install the skill using the CLI:
clawhub install gmail-sender
- Set the necessary environment variables in your shell profile:
export GMAIL_USER="[email protected]"
export GMAIL_APP_PASSWORD="xxxxxxxxxxxxxxxx"
- Make the script executable:
chmod +x gmail-send
Gmail Sender Skill Data Schema & Taxonomy
The Gmail Sender Skill operates as a stateless utility, processing input parameters to generate standard MIME emails. It does not store persistent data locally, relying instead on environment variables for configuration.

|---|---|---|
| Recipient | CLI Argument | The destination email address |
| Subject | CLI Argument | The subject line for the outgoing email |
| Body | CLI Argument | The plain text content of the message |
| GMAIL_USER | Environment | Your authenticated Gmail address |
| GMAIL_APP_PASSWORD | Environment | The 16-character secure token |
Gmail Sender Skill Advanced Features
- Seamless integration with Unix cron jobs for automated scheduled reporting within Openclaw Skills.
- Support for Python subprocess calls, allowing other agents to trigger emails programmatically.
- Dependency-free architecture ensuring high performance and compatibility across various Python 3 environments.
- Security-centric design that prioritizes environment variables to prevent credential leakage in version control.
