This is a ThreeScripts attack, the link in the email goes to:
[donotclick]wagesforinterns.com/concern/index.html 
and it then runs one or more of the following scripts:
[donotclick]billigast-el.nu/margarita/garlicky.js
[donotclick]ftp.arearealestate.com/telecasted/earners.js
[donotclick]tattitude.co.uk/combines/cartooning.js
in this case the payload site is at
[donotclick]northwesternfoods.com/sg3oyoe0v2
which is hosted on 23.239.12.68 (Linode, US) along with a bunch of hijacked GoDaddy sites (listed below in italics). The payload appears to be an Angler Exploit Kit (see this example).
