Gblock — Block email tracking in Gmail

Gblock protects your Gmail privacy by blocking email trackers. It stops senders from knowing when, where, or if you open an email, shielding you from spy pixels, tracking links, and read receipts. Gblock also hides your IP address and anonymizes your activity using a secure proxy. With automated tracker detection, it stays updated to block the latest email tracking techniques so your inbox stays private and protected.

✔️ SPY PIXEL PROTECTION

Spy pixel tracking is a sneaky technique based on adding an invisible 1x1 image, known as a "tracking pixel," to an email. When you open the email, this pixel sends information back to the sender, revealing details like when you opened it, where you were, and what device you used. All of this is done without your knowledge or consent, making it a serious privacy concern. Gblock detects and blocks tracking pixels, providing complete protection against spy pixel tracking.

✔️ TRACKING LINK PROTECTION

Link tracking involves adding custom tracking parameters to URLs, such as "?utm_source=newsletter", or embedding unique tracking codes. Some email marketing tools take this a step further by using URL shorteners to obscure the final destination, making it impossible to remove tracking parameters. Similar to spy pixels, tracking links can expose your location, device details, and other personal information. Gblock protects you from tracking links in two ways: Stripping all known tracking parameters from URLs, and using our proxy server to follow email links, masking your IP address and fully anonymizing your activity. Our proxy also caches responses, so if a tracking link is shared among multiple users, we already know the final destination and can serve it directly without accessing the tracking link. We are confident this would cover you for 99% of the cases.

✔️ AUTOMATED TRACKER DETECTION

Traditional tracker blocking relies on static lists that need constant manual updates, but trackers evolve rapidly, making this approach outdated. Gblock takes a smarter approach with automated tracker detection. Instead of relying on predefined lists, our advanced logic dynamically identifies and reports new trackers in real-time. When Gblock detects a previously unseen tracker, it instantly analyzes its behavior and reports it to our server. This ensures that future emails containing the same tracker are automatically blocked.
