Use Arial font in SO10 text for mail

Hey,

We got a report which is sending reminder mails to the employees. The customer wants those mails to be in font size 10 and font type arial.

The font size I think is adjustable via SE72. I also tried to set a 'font family' here. But I couldn't find 'arial'.

I already experimented a bit with SE73 to create a font family.

But I'm still not sure if I can use the typical 'arial' font type (like we got it in Word) in my mails. Do I first have to import that font or something like that?

Thanks and kind regards.
