Data Validation and Import Settings

During import, all email addresses are checked for validity. If the number of badly formed addresses exceeds the allowed threshold, your import fails. If your list is imported successfully, it is processed according to the rules specified in Admin > Main Settings > List Import. You can check these rules, and change them if they do not suit your purpose.

Selecting any one of these options starts the process of generating a unique new list, using the selected method and starting with the current file as the basis. Each method creates a new list file and initiates the New from Existing List wizard, which assists you in the process of populating the new file with a new list.
