I haven't heard from your app. It must be dead.
Your application pertiodically sends heartbeats to Deadmailer, to report it's still working. Deadmailer monitors those heartbeats. If Deadmailer doesn't get any heartbeats over the specified period, it assumes that your application is down, and alerts you by email, sms, or webhook.
Try it (it's free) and rest easy knowing that your critical tasks are running as expected.
