Spy Pixel Blocking
Invisible 1x1 tracking pixels are detected and blocked before they can report your activity.
Learn more
Spy pixels (also called tracking pixels or web beacons) are tiny invisible images embedded in emails. When you open an email, these pixels load from a remote server, revealing:
- When and how many times you opened the email
- Your IP address and approximate location
- Your device type and email client
Gblock detects and blocks these pixels before they can load, keeping your email activity completely private.
Link Anonymization
Strip tracking parameters and route clicks through our secure proxy to hide your IP address.
Learn more
Email links often contain tracking parameters (like UTM codes) and redirect through tracking servers. When you click, marketers can see:
- Which links you clicked and when
- Your IP address and location
- Your browsing behavior after clicking
Gblock strips tracking parameters and routes your clicks through our privacy-safe proxy, so trackers only see our server - not you.
Auto-Updated Rules
Our detection engine updates automatically, adding new trackers daily.
Learn more
Email tracking evolves constantly. New tracking services appear regularly, and existing ones change their methods to evade detection.
Gblock's detection rules update automatically in the background - no manual updates needed. We currently block over 15635 known trackers and add more every day.
Real-time Detection
Unlike static filter lists, Gblock detects new trackers dynamically as they appear.
Learn more
Most privacy tools rely on static blocklists that only catch known trackers. Gblock goes further with intelligent real-time detection:
- Analyzes email content as you view it
- Identifies tracking patterns even from unknown sources
- Blocks suspicious pixels before they can report back
This means you're protected even from brand-new trackers that haven't been added to any blocklist yet.
