Hi, I'm using the following link method to incorporate the Google font "Lato" into my email design:

<link href="https://fonts.googleapis.com/css?family=Lato:300,400,700,900" rel="stylesheet" type="text/css">

I'm also wrapping all the text in the body with the following span:

<span style="font-family: 'Lato', Arial, sans-serif !important; font-weight: 300;">Text</span>

It looks great everywhere, and if not the fallback works, except for the Outlook app on iOS. In the Outlook app all the text is bold. Here's a link to the screenshot from my iPhone:

Any ideas why this might be happening?

Thanks!
