Email Template Settings
On the right-hand side of the email template, there is a drop-down menu to define the "Form Language"
Changing this will translate any element of the template that you cannot directly edit the text of, however, it will not translate any content that you have written yourself. Such as, the "write a review" button or the main body of the email. You would be required to add those translations yourself.
Defining the language within the email template will also make sure that the Collector Page is displayed in the same language. Note: If you want the users browsers settings to determine this you can use the "Auto" option.
