When you create the Enrichment campaign, you will need a CSV file. Please consider the following information:
Closely supports only CSV format (UTF-8 encoded)
the file size should not exceed 2MB
each cell has to contain only one value (one email, one name, etc.)
the mandatory field for the CSV file is the LinkedIn link to the contact's profile. A header for the columns is obligatory
You can also upload the CSV file, which contains other columns. They will be used as the custom data for your AI prompts
