NIP First report after activation dealing with email address

Not sure if posting this in the proper area but I don't see a Norton Identity Protection Forum:

After activating my new account I got a notification report about my email address with the suggestion to change the password.  The problem I have with this is not knowing where the alert is coming from.  Is this just my primary email address password or from somewhere else?  I use my email address at quite a few websites as the username.  It would be helpful if the Alert Notification would specify where the possible threat is originating from.

Thanks!
