Identify and clean hard bounce lists in Automation 2.0

Identify and clean hard bounce lists in Automation 2.0

Hello.

1. I want to know how I can identify hard bounces in the lists I created to clean them before sending an email, given that the bounce rate has increased and it is necessary to clean the lists.

2. How can I exclude hard bounces and invalid emails from the synchronization I have with CRM? Is there a filter to do this?

3. How to clean up valid email lists and hard bounces?

Thank you.
