With all those disgusting marketing emails that overflow your inbox, not just one product is challenged. You also keep track of whether you opened the email, when you opened it, and where you were at that time by using software like MailChimp to embed the tracking software in the message.
How does it work? A single tracking pixel is embedded in the email, usually (but not always) in an image or link. When the e-mail is opened, the code within the pixel sends the information back to the company's server.
Some attempts have been made to limit the amount of information that can be transmitted in this way. For example, since 201
4, Google has been providing all images through its own proxy servers, which could hide your site from at least some tracking applications. Enhancements such as Ugly Mail and PixelBlock are designed to block trackers in Chrome and Firefox.
There is also a simple basic step to avoid trackers: Preventing your email from automatically loading pictures, since most pictures are there These pixels are hidden. You will not be able to avoid all the trackers that hide in your email that way, but you will stop many of them.
This is how it works in key desktop and mobile email apps:
