Everything we do seems to be tracked these days, even when we open our emails. According to Wired.com, “Marketers—or anyone who’s inspired to snoop—simply insert a transparent 1×1 image [pixel] into an email. When that email is opened, the image pings the server it originated from with information like the time, your location, and the device you’re using.” This type of tracking is legal (Google even has a support page on how marketers can do this) and there are many pixel tracking entities out there. PixelBlock is a Chrome Gmail extension that will block these tracking attempts. I’ve added it to Chrome and the above is a sample email in which the tracking was blocked as indicated by the slashed red eye. If you are like me and want to discourage such tracking, and you use Gmail on Chrome please visit PixelBlock to add this extension.
