You can go into your account settings under Personal Info and Privacy\Manage Your Google Activity and toggle your location history if you want to turn it off, but I've never had them update me via email. Given how much information is in that, I'd be surprised if they prompted anyone to go review it since most folks would likely feel like it's creepy to see a map of everywhere they went.

In maps.google.com (just tried on phone), make sure you are logged in, then settings -> Google Location Settings. Then open "manage activity".

I'm sure I get it by email approx once per month.
