I know there are different ways to see the leads that did NOT receive the emails due to bounces (results, filters, etc) but it'd be so nice if I could click to the list from the email tab.
Sigh. I agree with you. I do this every Monday. I have to create the smart list to determine which emails are invalid and which ones bounced because of spam. If only that harbounce list is clickable and can filter which ones are really invalid, it'd make my life easier.
