Sending messages to inboxes that constantly refuse them affects your reputation as a sender in various ways:
When sending a message to a list triggers a high number of bounces, it means that the list is "dirty": it contains old, incorrect, or otherwise unreachable addresses, which simply should not be there. Maintaining your list "clean" is extremely important: it affects your reputation as a sender, and it also affects your ability to properly analyze the overall performance of your campaigns, ensuring that what you are looking at are accurate statistics. It also impacts your total delivery time, since you are (unnecessarily) sending messages that will not be delivered.
With regard to your reputation, consider that Internet Service Providers (ISPs) keep track of your activity as a sender (they identify you in a variety of ways, including your IP address and domain) and monitor the amount of bounces that you produce (email delivery errors). If that amount exceeds certain parameters, action will be taken, varying from blocking your messages for a certain amount of time to reporting you to one or more blacklists. This will lead to even more bounces, and more delivery problems. So, mail delivery errors can negatively impact your short and long term deliverability
