Chapter in this post:
If you receive newsletters or emails with special offers, it may contain tracker pixels. These pass on information to the senders. When was the mail opened? Has it been read several times? Or was she ignored at all? Because the small and often invisible graphic provides feedback when it is loaded, these questions are answered. The data obtained can then be used to create analyzes and to develop and apply improvements for e-mail marketing. If you want to keep a secret of whether, when and how often you open newsletters or promotional mails, the mail plugin will help you MailTrackerBlocker continue.
As two readers with the version number 9.3 of Apple Mail have already written to me, the mail program acknowledges every attempt to start with a crash. As far as I could read, they both had El Capitan installed and the plugin was supposed to be compatible.
If you have this case, you have to go to the Library go and delete the plugin there (Thanks, Peter!):
The MailTrackerBlocker plug-in is compatible with the Mail app on the Apple Mac and works macOS 10.11 El Capitan. The add-on blocks email trackers, read confirmations and spy pixels. In the mail information about the actual e-mail, a small symbol (in X in a circle) appears after the installation of the plug-in, which shows with a number next to it whether and how many trackers have been blocked in the selected e-mail. Among the around 50 trackers that can be blocked with MailTrackerBlocker are those from these well-known service providers:
The mail plug-in for macOS on Apple Mac, iMac and MacBook is open source and free. You can find the download with this link. You can also find that on the product page Link to GitHub, where the developer Aaron Lee discloses all components of the software. On the first linked page in this paragraph you will not only find the MailTrackerBlocker download and the complete list of the tracker pixels that can be blocked in emails, but also instructions for installation. This is translated into German as follows:
With current macOS versions such as macOS 10.15 Catalina it may be that there is no button for plugin management in the mail settings. But that doesn't mean that you can't use Aaron Lee's add-on. Because with a small command in the macOS Terminal you can get the missing button back:
sudo defaults write "/Library/Preferences/com.apple.mail" EnableBundles 1
