How to specify language in mailSend() for multilingual questionnaires

Question

Hello,

I am working on a questionnaire with multiple languages and need to send automated emails using the mailSend() function. I would like the email to be sent in the same language as the questionnaire the respondent is currently taking.

Here is my current PHP code:

$voucher = readGET('voucher_code', true);

if (trim($email) !== '' && trim($voucher) !== '') {
    mailSend($email, 2, 0, $voucher);
}

My question: Is there a way to specify the language when using mailSend(), so that the email is automatically sent in the respondent's current questionnaire language?

I have looked at the documentation for mailSend() but couldn’t find a clear indication of how to handle multilingual emails dynamically based on getLanguage(). I would like to avoid having to create separate email templates for each language.

For context, I have already set up the language in the contact file, and respondents receive the invitation email in the correct language.

Thanks a lot
