So my company has a font and they have sent me the woff/tff/svg files.

We currently use a custom font for some of our emails but I think they are on our computers already hence why it works (I know outlook 2013 is notorious for not playing well with fnts)

My question is if I upload these fonts then use CSS to implement them, will they work? And is it possible for the font to "gracefully degrade" in case it does NOT work to Arial?

Thanks! Ive never uploaded a font or used a custom one except for google fonts
