Hello @Brian1220 ,
Based on what I'm seeing in your account, your main bounce types are suspended and undeliverables. For undeliverables our system will continue to try and send over the course of 3 days, in case it was just the receiving network having issues. Suspended bounces are the results of a contact bouncing back to us as non-existent multiple times - either through you or another customer of ours sending to that address.
For more info on bounces and managing them, I'd recommend checking out this article. If you have need further assistance regarding this, I'd recommend speaking with our Delivery team.
