In order to delete a subscriber go to Subscriber - Management --> Delete subscriber. This will open the familiar search mask allowing you to look for a subscriber. Once again you may use a simple or an enhanced search (see chapter "Edit Subscriber").
Fig. 7.3.3 - Delete Subscriber
Once you found and selected the subscriber(s) you want to delete, click the "Delete"-button. After confirming your choice you will see whether the subscriber(s) was/were successfully deleted.
Once all of the subscribers you wanted to remove are gone, you may return to the main menu by clicking on the "Back"-button.
PLEASE NOTE: This way of deleting is not meant to be used to delete entire mailing lists. While this process would work, it would take a lot of time for larger lists. Use the feature "Delete Mailing list" from Mailing list - Management instead.
