How to Block unwanted email from Apple?

My email address is constantly being flooded with iTunes emails every day. They are from the official itunes email address and I'm just getting sick of it. I've tried unsubscribing from the mailing list (I've done this 6 times over the course of two weeks total but to no effect) and even when I mark the email as junk in the mail app on my phone, it still ends up in my Inbox BUT NOT the Junk Folder.

Gonna have to report this email address to my ISP to hard-block if Apple doesn't get their act together.
