The documentation at https://wiki.foxycart.com/v/2.0/i18n#customising_the_email_subject
describes a technique for translating the subject line of the automatically-generated e-mails that FoxyCart sends to my customers.
But that technique only affects the *Receipt* e-mail, right? I presume that all
e-mails (including dunning) use the same template (which I can customize in the Admin at TEMPLATES -> email receipt), but that any e-mail which isn't the Receipt e-mail gets its subject line from the template set (TEMPLATES -> language) and ignores the customized Receipt e-mail subject. (Certainly, the fields available at TEMPLATES -> language do include input boxes for subject lines of other e-mails, such as the dunning e-mail [TEMPLATES -> language -> email -> "subject subscription past due"].)
Please could you confirm!
