How can I set app renewal notices without a custom database trigger?

Hi there, I have a quick question about renewal the app without any notice. I have done all my research earlier and didn’t find anything. So I think we have to make it custom with database trigger If this kind of thing is possible or make third party custom alarming system on which we statically add the name of app and its integrated date before expiration we get a mail or message from it. Please help me out on this.
