The Import Wizard offers several options to import subscribers and subscriber related data.
Subscriber record data may be stored in the original Subscriber record, custom data that you have defined, or relational data tables. The Import and Export wizards allow access to this data.
Options in the wizard include importing Subscriber Data and adding Subscribers to a list or importing data related to your subscribers into Relational Data tables. Additionally, you can launch a Lifecycle Campaign to new Subscribers once the import is complete.
Accessing the Import Wizard
Subscriber and Relational Data Import can be found in the Subscribers menu. To access the Import wizard, go to Subscribers > Subscriber Management > Import Subscribers.
This will open the Import Subscribers page, a wizard that will guide you through making several decisions to import data.
