If you are looking to unsubscribe to the Newlabel email, you can see an option when you log in to your Account.
Underneath the light boxes, you will see a line of text with an Envelope next to it that says Manage Your Trade News Subscription. Once you click on this you will have the ability to click all the boxes off, some, or unclick all of them. You will then see a box underneath on the right-hand side that says Update Subscription to edit or Unsubscribe from Newlabel emails.
