Post notification fails, no way to re-trigger

I’ve had several times over the past 2 months when this plugin has failed to send new post notifications. Sometimes it works, sometimes it doesn’t. The biggest frustration is there’s no way to re-trigger a new post send. It happened again this morning– a new video post type went from scheduled to published and no message. So I’v tried changing it to pending review, then changing the post time and publishing. But so far nothing again.

My guess is that I’ll have to manually create the email again. I just wish there was some other way to work around this.
