The ListUnsubscribers method retrieves a list of contacts that unsubscribed after a given dateTime.
Please note: the API method below is deprecated in favour of the ListSuppressedContacts method. Alternatively, we recommend moving to version 2.0 beta of the API as it contains the most recent functionality (available in both SOAP and REST).
It should be noted that the ListSuppressedContacts method can only be used to retrieve up to 1000 records.
