An email that notifiies you that one of your devices has stopped mining

yesterday i restarted my pc and i forgot to start salad. I missed out on 9 hours of mining As you can tell i was pretty annoyed. So We would like a feature where it can notify you if you stopped mining on one of your devices for more than a certian period of time. You can unsubscribe from the email, Or change what email the notification is sent to. Thanks!
