Only two possibilities here really, either you're logged into Home using a different account than you think you're using - check the app to ensure you're using the account you think you are, or for some reason the email is being filtered into spam or another folder you have set up due to some other rules and you'll need to find it. I'm not sure what email you're talking about, though, but try to search your inbox for keywords related to what you're expecting or even just "Google".
