This would be useful for our Gift Officers to track email communications. All Gift Officers would be able to quickly review the last interaction with the Constituent. It would eliminate the need to copy the email's body into a Note. Also is difficult to do using a mobile device. Ideally, using the Blackbaud for Outlook Plugin, the Gift Officer selects a Constituent then when the Action is created the email being sent is associated to that Constituents Record in NXT. Storing the email as an Attachment. (Idea comes from legal case management software with this feature). 

I've also seen where using a certain phrase in the email's Subject automatically BCC's to the Constituent's Record.
