I have a multi-language website (3 languages). When people sign up (through the standard wp register form), I want them to be added to a Mailchimp list (if they checked the marketing option). I have one list per language. How can I get them signed up on the right list. Users can change language, but their preferred language is not saved to their profile, so I can’t add them to the correct language Mailchimp.
