Hello,
Do you use built-in Email builder for your emails? Unfortunately, the built-in email builder does not have the option to translate emails to multiple languages. You can only create different emails for the different bulling countries https://gyazo.com/c8749091791c3156a2054534d8609ee5
Create feature request here https://www.8theme.com/taskboard/ to inform that you and maybe other users need this feature.
Use default WooCommerce email templates till we add that feature for the email builder.
Regards
