When we were sending through Online Express in the past, I was able to easily report on the performance of these messages by creating a constituent query in RE that looked for the Assigned Appeals for each donor. I could filter that down to only email, and the response of each donor was logged in the Response field.

For NXT, I have found that those messages are listed as Appeals associated with the constituent's record in RE, but there's no response history listed. It would be incredibly helpful to have this NXT email information accessible through RE queries as it has been for Online Express emails. As an agency we work with multiple organizations who are transitioning from OE to NXT, and this change in reporting options has been very time-consuming and difficult to compare OE and NXT email sends.
