Hello,
My native language is English and I also speak Spanish. While adding a user to my workspace it generates an introductory email with instructions and links that will be sent to the new user's existing email, and because my preferred language is English it generates this email in English. However, this new user doesn't speak English, they speak Spanish, so this introductory email isn't very useful and they can't just translate the text because the links take them to English places...
There is a "preview & send" option, and this is where I propose adding a pulldown menu to change the language in which this introductory email will be sent.
it = the non-human version of the they/them
