'Google email verification' message
If you've received an account verification email in error, it's likely that another user entered your email address while trying to create an account for another email address. If you didn't initiate the request, you don't need to take any further action. You can simply disregard the verification email, and the account won't be verified.
To prevent someone else from using your email address for a different Google Account, simply reset the password on the account.
