Preference Sites allow you to create custom profile management pages which contacts can access to update demographic information and manage list subscriptions. You can also use Preference Sites to create highly customizable subscribe and unsubscribe sites.
You can use Preference Sites to create each of the following types of sites:
Manage Preferences - Create a form or series of forms and pages to allow contacts edit demographic information and manage list subscriptions. Manage in a Customer Key realm requires Customer Key in the form.
Subscribe - A subscription mechnism with follow-up pages which allow you to ask for additional information, such as demographic details, as well as provide more information about your product or company. Subscribe is not available in Customer Key realms because no key yet exists for new Contacts.
Unsubscribe - An unsubscribe link with follow-up pages which allow you to ask for additional information, such as reason for requesting removal. Unsubscribe in a Customer Key realm requires Customer Key in the form.
