I'm running a D7 multilingual site and I want all registered users to be part of a required list, in order to send them a newsletter.
However I want to send the newsletter in the language set as their preference in their user profile.
I was thinking to use the standard language settings field of the user profile and merge it as a mailchmp field , to use a single list on Mailchimp.
But I don't see this field on the "merge fields" dropdown in the drupal mailchimp module configuration.
Any tips how to manage that ?
