Notified flag?

I have MP3 pro but thought I might get some user feedback here. I am experiencing unpredictability in emailing new post notification. It is difficult to test because then the post has been flagged as no longer new. I have done just test posts to a single subscriber list and it was fine but then it emailed again to the full list after I had trashed it.

I am getting nowhere with MP support but what woudl solve it would be a “simple” feature…

Have an MP checkbox on each post on the posts screen showing whether MP considers it to be “New” or not. This could be checked or unchecked to give user control over the notification process instead of it being a hidden property.
