2. How To Update Hard Bounced Subscribers

Hard bounces are a subset of undeliverables that have bounced due to being invalid. Typically, hard-bounced email addresses are misspelled, old, or for users or domains that no longer exist. To eliminate the chance of including these known invalid email addresses in future email sends, ExactTarget recommends updating your internal database appropriately, as well as uploading these addresses into your All Subscribers list as Unsubscribed.

Please note that after you complete the first procedure, the system outputs a CSV file that you will re-import into the system.
