You can import customer data in the form of a CSV file from the Blueshift UI by creating an import task.

CSV file

You must prepare a CSV file that contains the customers data. The file must be in Unicode (UTF-8), Unicode (UTF-16), or Western Europe (ISO-8859-1) format.

For information about data types, user attributes, and data formats, see User attributes to import.

When you create a task, you can click Download Sample CSV to get the sample data file.


File size

Files up to 3GB can be uploaded via the dashboard. For larger files, coordinate with your Blueshift Success Manager to determine the most optimal process.
