If you want to edit the information of an individual subscriber, find the subscriber on the Subscribers page and click the email address. Then go to the Subscriber information tab on the page that opens.
Additional subscriber information fields can be added through Settings.
Editing list memberships
On the List memberships tab, you can see the mailing that the subscriber is a member of. The folders that have lists which the subscriber in question is a member of are shown in a bold font.
By clicking the Show only subscribed lists, the lists of which the subscriber is not a member are hidden. The lists in which the subscriber is a member are shown under the folders. This feature is especially useful for those that have a lot of folders for address lists.
On the Grounds for sending tab, you can add or remove the subscriber's grounds for sending.
