hypothetically if we track every page URL even when a URL is appended with an email for sign-in how do we remove these from event tracked because it's becoming noisy and difficult to manage. The problem is we use this method to track every page load event in the system is it possible to omit when eg sign-in?@email.com

If you are tracking every page URL—including those with sensitive information like emails in the URL—this can quickly lead to noisy, hard-to-manage data and potential privacy issues. Here’s how you can address this in Mixpanel:
1. Omit Specific URLs from Autocapture
You can configure the Mixpanel JavaScript SDK to block Autocapture on certain URLs using the block_url_regexes option. For example, to block URLs that contain email addresses (such as sign-in links), you can use a regular expression to match those patterns: js mixpanel.init('YOUR_PROJECT_TOKEN', { autocapture: { block_url_regexes: [/sign-in\?[^\/]**@[^\/]**/] }, });LBKSThis will prevent Autocapture from tracking events on URLs that match the specified pattern, helping you avoid collecting noisy or sensitive data from those pages. You can adjust the regex to match your specific URL structure. You can also use .mp-no-track or .mp-sensitive classes to omit specific elements from being tracked if needed Mixpanel SDKs: Javascript.
2. Clean Up Existing Noisy Data
If you have already collected noisy or sensitive data, you can use Mixpanel’s Data Deletion tool to remove problematic events. This is a permanent action and should be used carefully. For example, you can target events with specific properties (such as URLs containing emails) and delete them from your project Data Clean-Up.
3. Best Practices
- Avoid tracking every possible event or property, especially those that may contain sensitive information. Focus on business-critical data to keep your analytics manageable and meaningful How to get engineering buy-in (and even excitement) on product analytics.
- Regularly review your tracking schema and use Mixpanel’s Lexicon to manage, hide, or drop events and properties that are not useful Lexicon: Describe your events and data using a dictionary.Summary:
Yes, you can omit tracking on specific URLs (like those containing emails for sign-in) by configuring block_url_regexes in your Mixpanel SDK setup. For already collected data, use the Data Deletion tool to remove unwanted events. Always review your tracking strategy to avoid collecting unnecessary or sensitive data.

If your pages are dynamic and you cannot pre-determine the URLs to block, Mixpanel provides flexible options to help you omit tracking for certain URLs or elements even when the exact URLs are not known in advance.You can use regular expressions in the block_url_regexes configuration to match patterns rather than specific URLs. For example, if your dynamic URLs always include an email address as a query parameter or path segment, you can write a regex that matches any URL containing an email-like pattern. This allows you to block a broad set of URLs without needing to list them individually Mixpanel SDKs: Javascript.Example: js mixpanel.init('YOUR_PROJECT_TOKEN', { autocapture: { block_url_regexes: [/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/] }, });LBKSThis regex will block any URL containing an email address pattern.Additionally, you can use the .mp-no-track or .mp-sensitive classes on elements you want to exclude from tracking, regardless of the URL. This is useful if sensitive data appears in certain elements rather than the URL itself.If you need even more dynamic control, you can use the block_element_callback or allow_element_callback options to programmatically decide whether to track an element based on custom logic at runtime Mixpanel SDKs: Javascript.In summary, even for dynamic URLs, you can use pattern-based blocking and element-level controls to prevent unwanted data from being tracked. Regularly review your data to ensure sensitive or noisy information is not being collected Autocapture Privacy and Security.

Based on the knowledge sources, the ability to block or filter events based on URL patterns—such as using blocklists or regular expressions for dynamic URLs—is specifically documented for the Mixpanel JavaScript SDK via the autocapture configuration (e.g., using block_url_regexes) Mixpanel SDKs: Javascript.For the Node.js SDK, which is used for server-side tracking, there is no mention in the documentation of a built-in configuration for blocking events based on URL patterns or similar client-side autocapture features. With the Node.js SDK, you have full control over what data you send to Mixpanel, so you would need to implement your own logic in your server code to filter out or modify events before sending them. This means you can programmatically decide not to send events for certain URLs, but there is no direct equivalent to the JavaScript SDK’s autocapture blocking options documented for Node.js Mixpanel SDKs: Node.js.Summary: - The documented blocklist and autocapture filtering features (like block_url_regexes) are available in the JavaScript SDK. - In Node.js, you must implement your own filtering logic in your server code; there is no built-in config for this in the SDK documentation.If you need to filter events by URL in Node.js, you would do so manually before calling the Mixpanel tracking methods.If you need more details or code examples for Node.js, please let me know!
