We were reviewing PowerMail sends and realized when we put together a query (or multiple) and send newsletters, invites, etc.. we don't have any idea of who we are not reaching as the result of users being flagged as unsubscribed or having bad email addresses. 

It would be the close of a very useful feedback loop for us to see who wasn't even sent a message as we had intended, along with the other data currently reported.

Picturing something like this:

Total Selected for Send: 425

Total Actual Sent:* 400 100% Select Members 

Members Who Opened: 150 x% Select Members 

Members Who Did Not Open: 240 x% Select Members 

Soft Bounces: 0 x%

Hard Bounces: 5 x% Select Members 

Total Bounces: 5 x% Select Members 

Unsubscribed (message not sent): 15 Select Members  *** NEW ***

Bad email address (message not sent) : 10 Select Members         *** NEW ***

This would allow us to more effectively track/update bad emails and follow up on unsubscribes as we come across them, and in general do better post mortem on our data.
