When you open a particular email to check the bounce, click on Hard Bounce (or whatever other type of bounce) to open the full SMTP response. At the top on the right-hand side you can filter by any bounce type. To view the detailed bounce information for each email, go to the Activity page for the Stream. Also, deactivated emails help you reduce credit usage since they are no longer sent messages. Keep in mind that each server’s bounce reports are independent and not associated. This is done to remain polite to the ISPs and improve delivery, as well as keep your database clean. The next time you send, these emails will be disregarded. When emails are identified as Hard Bounce or Spam Complaint they are automatically deactivated from your list. In Postmark, detailed information for each bounced email is provided.
