(1) It was sent from email using Yahoo, Outlook, Gmail and other free email service. That is a good sign that the company do not want you to know who you are.
(2) Email is not sent to you but in this case "undisclosed-recipients". That means, it was sent to the list of emails placed in the BCC address box.
(3) Any unsolicited email without "Unsubscribe" is illegal. If you receive email from someone you do not now but email has no "Unsubscribe" , just trust it.
(4) There is no sender's ID on this email. Other than his name ... there is no mention of the company name, address or website or telephone number.
Actually, this is one of the very bad example of SPAM.
