How do I report phishing email, and to what address do I send it?
I can escalate your concern, but there is no guarantee that you will receive a reply here. There is no email address that you can send this kind of issue to.
Norton is aware of many many scams out there, not just for Norton, but for all kinds of products with subscription based products.
EDIT
Was this phishing email for a Norton product offer? If so, you can first check the sender against this information. Is this email from Norton legitimate?
