It would be incredibly helpful if HubSpot users could create a list based on email errors.
There are times when I am sending out a mass email to thousands of contacts records and don't have the time to go through each one to know whether or not HubSpot actually sent an email. Adding a feature that allows me to quickly group these contact records into a single list would lead to a quicker record clean up process and allow my team to try alternative methods of contact for these specific records.
