I've already seen this suggestion https://waze.uservoice.com/forums/59225-map-editor-suggestions/suggestions/41506807-ur-reply-via-email but I thought this would be a nice compromise.

Let editors set an Editor Email in WME, that becomes the reply-to address on report emails (for those who don't know: there is a difference between the reply-to and sent email address). The sent email can be changed to something like userreports@waze.com and then the editor can just receive the reply to their editor email.
Just to clarify, by editor email, I mean our own email addresses we already have for editing related things (e.g. deviatefromtheplan.waze@gmail.com), rather than Waze creating email addresses for us.

Hopefully this is a good compromise!
