Helly Litmus Community,

I am working on a HTML e-mailsignature, using Foundation Zurb (compiles css to inline css). Now my gmail IOS app keeps chaing the design. It adds white space. I think it's because i'm seding it from outlook and it adds MSOnormal classes (with margin-bottom and margin-top's). I have removed the viewport metatag, and I have added a min-width to the body element. Still outlook won't send the desktop version for my mobile phone (which is what I want). Do you guys know how to force Outlook to only use the desktop version?
