Retrieve Subscribers by Subscriber Key
This page contains information about retrieving subscribers from an account or subaccount via the subscriber key. By retrieving subscribers from an account or subaccount using the subscriber key, you can pull back a complete view of all of the subscribers within that account. That view gives you the status of those subscribers and other information that can help you better target your sends.
