The CSAT survey email might not have been translated in the preferred language if any one of the following is true.
1. The language associated with the contact seems to be incorrect. The customer’s preferred language is auto-detected by Freshdesk and saved in contact details based on their first interaction. This can be changed under Contact > Edit Contact.
2. The survey will be sent in the default language if the translations for the customer's preferred language is not uploaded or available in Freshdesk.
3. The ‘secondary languages’ in your helpdesk should be marked as ‘Visible in portal’ for the surveys to be automatically translated to the corresponding languages
