Where do Apple ID reset emails go???

Woke up to find that my Apple ID was locked. Going through the motions to unlock my Apple ID, emails where sent. On both separate email reset attempts both my iPad and iPhone received push notifications from this app, in both occasions on both devices the app would not show or display the Apple ID reset email. I deleted the app, then reloaded Apples email app and after getting my Apple ID sorted out, the Apple email app has my reset emails. Why did this app totally conceal reset emails from Apple??? It does not make any sense.
