It would be extremely helpful if we could access a comprehensive list of undeliverable email addresses within the email send reports.

For example, if we upload a list of 50 email addresses and are informed that 10 will not be delivered, there is currently no efficient way to identify and extract those 10 addresses without manually reviewing each line. While this might be manageable for small lists, it becomes unworkable at scale, such as during a 30,000-email send.

If exporting the undeliverable addresses isn’t an option, we would at least request that they be clearly displayed in the "Did Not Send" list. This would allow us to reconcile email sends more effectively and follow up as needed to collect updated information.

This limitation has become a significant pain point for our team, leading to considerable time inefficiencies. We would greatly appreciate any enhancements to improve visibility into undeliverable addresses.
