How to fix wholesale product access issue for retail customers?

I accidentally sent out a email blast out with a button/link to a wholesale product page. When you click on the email link it takes you to the wholesale product page without having to log into a wholesale account. So retail customers are able to purchase wholesale items/pricing without logging in.

Also, in my retail site if use the search bar and search a specific wholesale SKU code, the searched item thumbnail is correct with retail pricing, but when you click on that product thumbnail it takes you into the wholesale product and pricing without having to log into a wholesale account.

Please advise.
