how to set the default font and its size in the email writing page?

Hello? I appreciate users’ contribution to Disroot service.

Could you please tell me how to set the default font and its size in the email writing page? Its default font is Arial and the size is 13. I think it is too small. Can you help me change the default font and its size?

Thank you.

hello, i saw no-one answered, so i will have a go [unless you already found out]. first, are you using webmail or an email client [like thunderbird]? second, which operating system [i can only help with Linux].

cheers, jacksprat
