Email Templates - Can we use internationalization (i18n) for email content?

Hello everyone,

We have seen the subject line is fixed for email templates and cannot be altered yet - and we think that this is due to internationalization (i18n). This runs well in our environment and we can switch the browser between languages and the subject line then follows those languages.

We have one outstanding issue: is it possible to configure the email content using the internationalisation function?

Thank you in advance for your help,
Kai
