At this time, Newsletter Emails and Legacy Newsletter Emails created in the desktop version of Constant Contact can only be scheduled & resent on our Moible App. These campaigns cannot be edited on the app. While on the other hand, emails created in the mobile app will show as a Custom Code email campaign on a Desktop.
