How do I turn off email notifications of new episodes from a iTunes season pass?

To be clear, this is not regarding general Email app notifications or regarding the Apple recommendations that you can turn off when managing your account. I have an iTunes season pass and while I get app notifications and notifications in my AppTV TV app (which is great) I also get unnecessary emails that I would like to turn off.

I have searched a bit on my account and these forums but haven’t seen anything about this. If it exists can someone direct me to that. Barring that does anyone know how to turn off the email notifications when a new episode of a seasons pass is available for download? I attached some screenshots of what I am talking about. NotE that when I click the “edit your preferences link in picture one just opens a browser window with a blob of text. I’m guessing this website is accessible in some other way? Thanks for your help!
