I wanted to translate emails sent to users after signing up using different language than English. I know there is a way to translate the system emails from the account settings translate tab, so I added the translations as you can see in this picture.
This didn't work. Maybe this is not enough. I tested it (registering a new account using Arabic) and it is not working: The system emails are still sent in English.
Does Drupal send emails according to user's preferred language? If yes, how can Drupal send registration email in a language that is not English?
