Hi Carey,
A couple things to take into consideration:
1) Do you notice multiple people from the same company registered? It could be possible that the original recipient forwarded the link the email to others in the company. To me, that could be where the 30 acquired by people came from since they couldn't have received the email if they didn't exist when you set it.
2) The landing page views are not unique. So if someone visited the page multiple times, each visit is added to the total. This includes any visits you and/or your team made to the page when creating, testing etc.
