Cleaning Up Email Bounce list and Email Validator

As we continue to use Gainsight for Outreaches/Programs and Cockpit/Email Assist, we are running into a frequent situation where a participant has been added to the bounce list and then cannot be sent further emails through Gainsight - Journey Orchestrator or Email Assist.

However, using the Email Validator under Administration > Email Configuration, we can typically find the email domain as blocking, reporting our sends as spam, or other errors that aren't indicative of an email address that no longer exists. As an Admin, I have permissions to view results of the Email Validator and remove emails from the bounce list one at a time. Our CSMs do not have this permission so they encounter a roadblock when trying to send an email in Email Assist or determine why a contact did not receive an email from one of our Programs (typically an operational notification).

I can/have created a report of Hard Bounces and the message that was received (similar to email validator) but I can't take action in Rules (that I'm aware of) from this information. We also have a rule to create a CTA if all sends for a Program bounce at a given Account, which helps reduce missed operational emails and assists with contact clean-up -- but the majority of the time these are legitimate email addresses that are able to receive email from our other outbound systems that just have to be cleared from Gainsight bounce list.

Is there a better way to review and remove emails in bulk from bounce lists? Is there a way to provide view-only access to non-admins to the validator?

Curious of other strategies that are being used to clean-up and maintain email lists without too much manual work.
