Default font size in mail app

[Florin Tiuga]

Greeting,
Does anybody knows if there's a way to change the default font size in the built-in mail app?
Or it has to be set for every new mail?

Thank you.

Is there any method to change the font size of specific app instead of the whole system? I am using built in MI Mail too. Thank you!
