Trackers get installed in links too of course. From the marketing [gurus](https://mysignature.io/blog/email-trackers-your-ultimate-guide/):
> Invisible image pixel allows you to **detect the exact time and date that an email has been opened**, allowing you to see the bigger picture of what the reader responds to and how you can cater to their needs better. 

> You can also add **redirects and special tags to the links** in your email, which makes it easy to collect data about what links are clicked, how many times, and by whom.

If you use a Mac, in general there's [LittleSnitch](https://www.obdev.at/products/littlesnitch/index.html) which can alert you to network calls and requests. It's pretty persistent and in-your-face but I have found really useful to tell you what's going on 'under the hood' of any app, site or service. If you are compelled to use Apple hardware of course.
