Sorry, but you can only locate your device, if "Find my" has been enabled, and you can see your Mac in the list of registered devices, if yo log into your iCloud Account on a computer.
You also get the message, that someone logged into your iCloud Account, using a Webbrowser, if this person was you.
And there will be no location mentioned as well in this mail.
The only time you will provided with location data would be, if someone has been using your Apple ID and the Two-Factor code has been sent to one of your trusted devices.
