Hello, I'm one of the authors of this work.

The code and data for the study is available here: https://github.com/citp/email_tracking (measurement platform here: https://github.com/citp/OpenWPM).

We also just released a blog post that highlights the main results (and is a quicker read): https://freedom-to-tinker.com/2017/09/28/i-never-signed-up-f...

Thank you very much for doing this work! I have recommended that my employer, who makes a popular email client, read this and consider adding these sorts of features.
