Email alert app - for specific email
My boss is looking for an Android app that will allow him to specify a specific email sender's address that will cause the notification to continuously alert him (like an incoming call rather than a short notification sound) when he receives an email from it. He is hard of hearing and he needs to be alerted when a specific fail-over occurs with our database server. He gets an email, but he usually doesn't hear the normal email notifier. And he doesn't want bells and whistles going off for every email he receives, just this one specific type.
Anyone know of something that will do that or have suggestions?
