Font-Awesome glyphs in messages

I would like to modify the Invoice Layout message to include icons for Facebook, Twitter, etc. These (and other) icons are available as Font-Awesome glyphs which would simplify size and alignment issues. Is it possible for these Font-Awesome glyphs to be used in eShop messages? If so, how do I add them?

Hello Steven,

I think this can be implemented by adding style inline into Messages. Please go to EShop -> System -> Messages to edit messages and add style inline for them and check if it works as your expect or not.

Sincerely, Giang
