You can import contacts by following the steps below:
Ensure that you have prepared an Excel spreadsheet with 3 mandatory fields: First name, Last name and Email address. Apart from the header, all rows must contain a contact entry.
Save the Excel spreadsheet as .CSV UTF-8. Not just CSV.
In Agility, go to > Discover > Private contacts then click on the Import Contacts button at the bottom of the screen
You can then follow the steps to import the contacts into Agility
In the import setup window, we suggest importing the contacts directly into a list. That way, the import will be easier to review.
