After uploading your file on the import page you are taken to the second stage of the import process. Go to the Advanced drop-down and select from the various options:
The process of importing can also be used as a way to update your mailing list. In most cases, you re-import your mailing list with updated recipient fields (i.e. new collected information).
Sometimes, however, you want to keep certain recipient fields empty, and do not want the import to overwrite it. Only in this case, check the box.
The default option is that country code and phone number are stored in one recipient field. However, you can also choose to separate the country code and phone number into two recipient fields for better segmentation.
Selecting this advanced option means that the imported recipients will be assigned to the group selected at the top of the screen and will be removed from previously assigned groups.
The option to Import as Pending and send confirmation request email allows you to import recipients as Pending. Once you send out the confirmation request email (see section below), those recipients who chose to subscribe to your email communications will become Subscribed. This option overwrites any previously recorded subscription status (Subscribed or Unsubscribed).
