Outlook and Fallback Fonts
As I'm introducing Google fonts into my emails, I have discovered that they don't work on a few of the Outlooks. That's fine. The problem is that the fallbacks don't work either. They just display as a plain serif.
I import the Google font in the head:
Then place in it inline:
<span style="font-family: 'Open Sans', Arial, sans-serif;">Text</span>
So, why would it not fall back to Arial or sans-serif?
