On behalf of a customer,
When an email fails due to a soft bounce, the current design is that an Admin must utilize email reporting objects (Email Log, Email Logs V2, Email Raw Events, etc.) in order to review the failures, since the email address will show as valid in Email Validator. This leads to extra actions being taken to review the failures.
It would be more efficient if Admins were able to review all email failures from within the Email Validator feature, by adding a separate tab or some other means, which integrates with the available reporting. This would provide for a centralized hub where Admins can review the failures, instead of the extra navigation and time spent.
Please take this into consideration for the future roadmap.
