It is a phishing e-mail. If you look at the link (by hovering over it like White Hat Mike explained), you will see that the domain name is account-validate[.]com. (I added the  around the dot so that you can not accidentaly visit the site).
If you lookup the whois information (whois.net), you'll get this:
Domain Name: ACCOUNT-VALIDATE.COM
Registrar: GODADDY.COM, LLC
Sponsoring Registrar IANA ID: 146
Whois Server: whois.godaddy.com
Referral URL: http://registrar.godaddy.com
Name Server: NS1.SUSPENDED-FOR.SPAM-AND-ABUSE.COM
Name Server: NS2.SUSPENDED-FOR.SPAM-AND-ABUSE.COM

Updated Date: 29-jan-2015

You can see that the domain was registered 3 days ago with GoDaddy, and that it is already suspended for abuse (see name server).
