Hi @PaulH294,
Thank you for your feedback and taking the time to reach out to the Community! I do sincerely apologize about this experience. Within Constant Contact, once an email bounces for the first time as "Non-Existent", we place them in a temporary 15-day hold, known as "Suspended". During this time, no one with a Constant Contact account will be able to send to this address. After this temporary hold, we will allow you to send to that address again. However, if it bounces back again as a "Non-Existent" address, we will place them indefinitely in this "Suspended" status. If you believe a contact has been put in this hold incorrectly, you can call into our Support team and we would be more than happy to investigate the address for you. You can find out more information about this Suspended Bounce category here: https://knowledgebase.constantcontact.com/articles/KnowledgeBase/6185-the-suspended-bounce-category.
