I created a list of over sixty contacts to export from Apple Contacts. After accessing my credentials from MailChimp, I simply dragged and dropped into the export pane of the app. A few seconds later it was uploaded, and confirmed on the MailChimp web site. My only gripe is that MailChimp Import only transfers the contacts first name, last name and email address. I’d like to import other details from my contact list, like business name, phone number, or whatever, but the app won’t do that. I’d give an extra star if import fields were more flexible.
