Once a FTP repository has been created for the purpose of importing CSV files, you will need to create a subfolder for each list.
A CSV file will be imported into a List whose ID matches the folder name.
You can create these subfolders:
- Manually (subfolders of the "import" folder)
- Using the MailUpSend.CreateList() method when the list does not yet exist
Please note that there is one set of FTP credentials (hostname, username, and password) for a specific MailUp account.
