If you hover over the link, should show up the web address.. if there are a few links in the email, they'll all be referencing to same address, if it's a scam.. Some of the scam emails give the impression that it's from linkedin - reuse of logos etc...
Check your linkedin a/c - should be getting information directly to that, first of all - assume that you don't have your settings open to allow email from everyone / anyone that can see you on linkedin..
