I am trying to import a set of contacts ( email address is primary field) into ListMembers of mailchimp. Although it says that the record is imported but I dont see same in mailchimp. Looking at the records imported it seems the id format of the record is d57f2eb66e$8e5c7313bc where the first part is the listid.
So all the emails which are already part of another list are not imported into new list, only the extra contacts are imported into new list.
Is this something that is a limitation at mailchimp or something missed in the mapping
