Norton Account email verify?

I created a Norton Account after installing NIS for the first time on my PC.  I recently received an email (looks like from Norton Symantec) which contained a link in it to "verify my Norton Account email address."  Is this legit?

 

Why would you guys be asking people to click in links in emails?  I did NOT want to do this because it could take me to a fake Norton page. 

 

If this is legit, what happens if I do not verify?
