Don't buy anything from a spammer
If an unexpected email brings you news that seems too good to be true, it is probably a spam and a scam.
If you didn't request information about the product or service, it is probably a spam and a scam. If it promises to enhance parts of your body, it won't. If it promises you an easy mortgage, you can do better by visiting your bank. If it promises that you can make a fortune on a penny stock, you can't. If you are unsure, ask five friends. Chances are four of them also received the spam and you can know to steer clear.
