Is there a way to show how many constituents in a given list would actually get an email sent to them by RENXT, rather than just how many constituents are in a list based on the list criteria? This would be helpful if, for example, I'm being asked to make sure I have at least 500 people on a distribution list for a particular event invite. I may see a list of 500 constituents after I select criteria, but it may only be 200 constituents with emails that RENXT can send to.  Happy to clarify if needed.
