What This Skill Does

The postmark skill provides a robust interface for the Postmark API, allowing OpenClaw agents to manage, track, and send transactional emails with industry-leading deliverability. Whether you need to trigger single emails, process bulk batch notifications, or utilize dynamic server-side templates, this skill streamlines your communication workflows. It also offers deep insights into your email ecosystem by providing hooks into bounce reports and delivery statistics, ensuring your automated messages reach the intended recipients without getting lost in spam filters.

Installation

To integrate this skill into your environment, use the OpenClaw installation command:

clawhub install openclaw/skills/skills/mrgoodb/postmark

Once installed, you must configure your server credentials to enable authentication with the Postmark API. Set your API token as an environment variable in your OpenClaw runtime:

export POSTMARK_SERVER_TOKEN="your-token-here"

Use Cases

• Automated Alerts: Configure the agent to send immediate notification emails based on system monitor triggers.
• Transactional Workflows: Send welcome emails, password resets, or order confirmations using pre-configured Postmark templates.
• Bulk Reporting: Use the batch endpoint to send large-scale updates to users while maintaining high throughput.
• Health Monitoring: Enable the agent to check delivery stats and bounce logs daily, reporting back any anomalies to the administrator.

Example Prompts

1. "Use the postmark skill to send a welcome email to [email protected] using template 88921 and inject the user's name as 'Alice'."
2. "Get the current bounce statistics for the last 24 hours and summarize if there are any significant spikes in delivery failures."
3. "Send a batch of status updates to the following list of users: [email protected], [email protected], and [email protected], notifying them that their subscription has been successfully renewed."

Tips & Limitations

• Rate Limiting: Always be mindful of Postmark's API rate limits. For high-volume sends, use the batch endpoint to reduce the number of individual API calls.
• Template Management: Always ensure that your TemplateModel object maps correctly to the variables defined in your Postmark dashboard to prevent rendering errors.
• Security: Keep your POSTMARK_SERVER_TOKEN in a secure location and never commit it to source control. Rotate your keys regularly if you suspect unauthorized access to your agent environment.
