We allow up to four soft bounces over 32 days for a given email address before removing it from your contact list. They happen when your recipient’s mailbox is full or temporarily unavailable. We remove those addresses from your list automatically. They can happen when the email address doesn’t exist, the inbox was deleted, or when the user blocked you as a sender. Bounces fall into two categories: hard bounces and soft bounces. A bounce is an email that is returned to the sender because it cannot be delivered for some reason.
