I think what you're looking for is your Profile Settings page, not your Account page. If you scroll all the way down to the bottom of your Settings page, you'll see a link to:

"Looking for Email? Check out your Newsletter Subscriptions!"

The Newsletter Subscriptions is a link to the page where you can uncheck the ones you prefer not to receive. That said, however, there's nothing in that list that refers to Wishlist items on sale notifications, so not sure whether that list will help you, or not.
