2. Import the file into Dotdigital Marketing
Go to Audience > Contacts, then expand the New contact drop-down menu and select Import contacts.
For File, select Choose file and select the same CSV file that you created in Step 1.
Optionally, for Email address to notify, enter an email address to receive a notification when the import is complete.Expand the Encoding type drop-down menu, then select Unicode (UTF-8).
Select Upload.
Map the following fields:
Email address to email
Mobile number to mobilenumberid
Any other data fields you want to import.
