I’m afraid there’s no direct tool in MailBluster that could help you keep the bounce rate under control. However, We recommend cleaning the list using services like neverbounce (https://neverbounce.com/) or debounce (https://debounce.io/) to improve your bounce rate. After cleaning your list, you may consider taking a dedicated IP from amazon. With a clean list and a dedicated IP, I believe you will have much more deliverability.
