Do you wish to prevent email trackers from tracking your emails? Maybe you should. There is one thing about those marketing emails (those that’d be always advertising to you) that many do not know. These emails actually do track your activities on them. They track whether you’ve opened the email, the time you opened, and where you opened (location data).

They are just emails, so how do they do all that? It’s simple. They use email marketing software like MailChimp, which hide trackers in them. These trackers are usually hidden in an image or a link.

So when you open the mail, the data is sent back to the company that sent the email. It doesn’t sit well with you, right? Google and others have made attempts to block these unseen yet annoying trackers.

Well, there are a few ways to tighten up your security aside from the ones Google and others have implemented. One such step to prevent email trackers is to stop your email from automatically loading images. This is a good step since these trackers called “pixels” are usually hidden in images.

This is not a final and complete solution to the problem but it will at least help avoid most of them. This piece is going to show you how to prevent email trackers from tracking your emails in major desktop and mobile email services.
