When pulling marketing data for emails, such as clicks, opens, transaction rates, etc., that functionality should be available for all emails regardless of when it was sent. You can only see the transaction information for the last 5 emails that were sent. But for new folks coming into an organization trying to gather information on how effective an organizations email marketing has been, having access to this data for every email would be helpful. Allow users to see transaction information on all emails in the system.
This function is already available.
Select [view all sent emails] (located at the bottom of the last 5 emails)
Many of the stats are in the columns.
