What is DoubleTick?
DoubleTick is a powerful email tracking utility specifically designed to give AI agents visibility into their communication workflows. By injecting a discreet 1x1 tracking pixel into messages sent via the Gmail API, this tool allows users to verify precisely when and how recipients interact with their emails. It is an essential component for any developer looking to build sophisticated Openclaw Skills that require feedback loops from outbound communication.
Beyond basic tracking, DoubleTick handles the heavy lifting of formatting by automatically converting Markdown content into professional HTML. This ensures that tracked emails look great across all clients while providing granular data such as open counts, timestamps, and device details, allowing for more intelligent automated follow-ups and data-driven decision making.
DoubleTick Use Cases
- Tracking client responses and engagement for automated project updates.
- Building intelligent follow-up sequences that trigger only if an email remains unopened.
- Monitoring the reach and effectiveness of AI-generated outreach campaigns.
- Validating that high-priority notifications have been seen by the intended recipient.
How DoubleTick Works
- The AI agent initiates a send request using the send_tracked_email tool, passing in recipient details and Markdown content.
- DoubleTick converts the Markdown to HTML and embeds a unique, invisible tracking pixel into the email body.
- The email is dispatched through the user's authenticated Gmail account via the Gmail API.
- When the recipient opens the email, the tracking pixel fires, logging the event on the DoubleTick servers.
- The agent or user can query check_tracking_status at any time to retrieve detailed analytics, including open count and device types.
