This is junk email. Just like the junk snail mail that clutters up your regular mail box, this will clutter up your email box. It is unsolicited commercial email, sent by a company that has no existing business relationship with you to get you to buy something. In other words, mass mailings you didn't ask for and don't want.

NEVER reply to a spammer or attempt to use a link that they claim will remove you from their list. This just proves to them that there's a real person at this address and you'll get more spam!
