We should be able to view Overall Performance Rates (open rates, click rates, transaction rates, unsubscribes, etc) for a specific time frame to see monthly (or how ever often) how well email is performing.

We should also have the capability to export email performance to track in our own ways outside of Raiser's Edge, especially since the capabilities within NXT are limited at this point.

We may want to see an overall email performance for the last month, but it would also be nice to be able see the performance of similar types of emails (appeals vs newsletters for instance).
