Media queries not working on iPhone's Mail

I'm facing a problem with a newsletter. I have included media queries in it so mobile viewers get something nicer. If I view my newsletter in a browser and resize it, I can see that it works fine, both on mobile/desktop. But when I view it through iphone's Mail app, my media queries are getting ignored for some reasons I'm not aware about. The mailbox I'm testing it with isn't a gmail one by the way.

Here's the head part of my code :

<head>

Has anyone an idea on why I can't get this media query working through iphone's Mail ?
