This is a real-life example why I suggest people use browser safe fonts in their email messages.
Since I don’t have the font on my computer, Outlook displays the font with the closest name…in this case, one with musical notes!
I suggest sticking with Arial, Calibri, Tahoma or Times New Roman. While Calibri isn’t a “true” browser safe font, it translates well on the web and mobile devices.
For my personal emails at work and at home, I use Calibri, 11 pt.
