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.
About the List ID to be used as the folder name
Please note that the List ID to be used as the folder name is the list number (e.g. 1, 2, 3...), not the List GUID
