Apple Mail Default font for authored email messages
Why does Apple not allow you to stylize your email messages with a default font like every other mail client? The mail app on MacOS has remained largely unchanged for 20 years. I can only assume that Apple thinks that fonts should never be used, ever and the font allowed in an email message should only be determined by the receiver. As long as I choose an email font and size for each and every email message individually it is allowed, but not by default. The Font selection in Preferences only show how you see messages that have no individually defined fonts. To see this, change your message font and see that your sent messages now show a different font.
