Tracker Blocker: Stop trackers in emails

Tracker Blocker is a Chrome extension developed by GMass, Inc. that aims to stop open-tracking pixels from working in emails. This free extension is a must-have for two types of users.

Firstly, if you send cold emails or use email marketing platforms like GMass, YAMM, Mailshake, or Lemlist through Gmail, you want accurate open tracking. Currently, when you open your own email from your Sent folder or open a bounce notification, the open-tracking pixel fires and registers a false open in your campaign reports. Tracker Blocker prevents these "false opens" from being registered, ensuring accurate tracking.

Secondly, if you're a privacy advocate who doesn't want "opens" to be registered on emails sent by email marketing platforms, this extension is perfect for you.

It's important to note that Tracker Blocker currently only blocks open tracking pixels from GMass, but the developers plan to extend this functionality to other platforms in the future. Additionally, this extension is built on the latest technology from Chrome's new Manifest V3 program, ensuring effective blocking of email tracking pixels. Unlike other similar extensions that haven't been updated in years and will soon stop working, Tracker Blocker is actively maintained and supported.
