Privacy Considerations

  • • Tracking pixels raise privacy concerns. Always disclose tracking in your privacy policy.
  • • GDPR and other regulations may require explicit consent for email tracking.
  • • Some jurisdictions consider open tracking as processing personal data.
  • • Provide an easy way for subscribers to opt out of tracking.

Apple Mail Privacy Protection

Since iOS 15 and macOS Monterey, Apple Mail Privacy Protection pre-fetches tracking pixels through proxy servers, regardless of whether the user actually opens the email. This means open tracking data for Apple Mail users is unreliable. Roughly 50-60% of email opens may be affected. Consider using click tracking as a more reliable engagement metric, or focus on conversion-based metrics instead of open rates.

How tracking pixels work

  1. A tiny 1x1 pixel image tag is embedded in the email HTML
  2. When the recipient opens the email, their email client loads the image
  3. This sends an HTTP request to your tracking server with the campaign and subscriber IDs
  4. Your server logs the open event and returns a transparent 1x1 pixel GIF or PNG
  5. This allows you to track who opened the email and when

Limitations

  • Images must be enabled in the email client for tracking to work
  • Some email clients block images by default (e.g., Outlook desktop)
  • Privacy proxies (Apple, Hey.com) can inflate open counts
  • Plain text emails cannot include tracking pixels
  • Firewalls and security scanners may trigger false opens

About this tool

Email tracking pixels are invisible 1x1 pixel images embedded in HTML emails. When a recipient opens the email and loads images, the pixel makes a request to your server, recording the open event. This is how email platforms track open rates. Use this tool to generate tracking pixel code for custom email systems or development projects. For understanding your open rate data, use our open rate calculator and CTOR calculator. If you are building your own email infrastructure, also check our UTM builder for link tracking.
