For some of the various e-mails:
Go to the top of the page. There's a bar of links: "News/Reviews.... Profile/Settings...."
Click on "Settings"
In the links down the left column, there's "Edit Options". Clicking on that brings you to a page with many options you can turn on and off, some of which relate to e-mails.
Also on the setting page, scroll further down and you'll see "User Tagging". Click that link, and you'll reach a page that allows you to restrict or hide certain other alerts which may be annoying to you.
