Got emailed by secureserver.net

Hi everyone,
Secureserver (which is what I used when I got my domain from Godaddy) emailed me, phrasing it as if the guy was one of the users of my website. He wanted the thing he didn't get for doing a survey (like 99% of things behind surveys). Should I be worried? Do they care about CPA sites?

depending on where you live, (if in US, your in luck)
email you have not requested (BY ANYONE) is considered spam, so delete it and move on
