Hi everyone! I'm sending some emails about products to customers who bought something last year but that are not confirmed opt-in. (We have several subscription categories) Is there a way to insert the link of the subscription center in a marketing template email to let these contacts subscribed if they want? this because the standard opt-in email doesn't manage languages!! The system template has the languages but even if in the customer the language is not english the email is in english! Any ideas? Thank you :)

You can use setup email templates in each language, and use Workflow with conditions in each send email action with condition for the customer language (based on custom field value).
