How to avoid your emails from being tracked
A single pixel tracker is installed in the email, commonly hidden within an image or link.
All those disgusting marketing emails stacking your inbox aren't just promoting a product. They also track if you've opened the email when you opened it and our location at the time by utilizing software like MailChimp to install the following software in the message.
How does it actually work? A single tracking pixel is installed in the email, commonly hidden within an image or link. When the email is opened, the pixel code sends the information to the company's server.
There have been some measures to limit the amount of information that can be transmitted in this way. For example, since 2014, Google has served all images through its proxy servers, which could hide your location from at least some tracking apps. And extensions like Ugly Email and PixelBlock have been developed to block trackers in Chrome and Firefox.
You can also take a simple essential step to avoid trackers: prevent your email from loading images automatically as images are where most of these pixels are hiding. You can't control all trackers that can be hidden in your email this way, but it will stop many of them. Here's how to do it on the major desktop and mobile email apps:

1) Click the gear icon in the upper right corner to access your settings and click "View all settings."

3) Select "Ask before showing external images".
4) Scroll down to the bottom of the page and click "Save Changes."
DISABLE AUTOMATIC LOADING IN MICROSOFT OUTLOOK (OFFICE 365):
