The Google Adsense Scam Email
To make the email appear even more legit, the scammers spoofed Google's email address to make it seems as if it was sent by them. But, whenever you receive a Google Adsense Suspension email and want to know if it is legit or not, just go directly to https://google.com/adsense/ and attempt to sign in. If you are able to sign in and view your account information, it means the email is a fake.
If you were tricked by the Google Adsense scam, please change your Google password immediately before your account is hijacked and used fraudulently. If you are unable to gain access to your account, please click here for help regaining access.
