On Udimi you buy clicks. We track and filter (https://udimi.com/filter) all traffic delivered by your seller and give you access to the collected stats. We can see IP, browser, location, internet provider, and operating system of the visitors.
You can see the details of the received clicks in the Stats section of your order on the %orders% page.
But since we don't have access to your lander, it's not possible to get more information about the clicks, such as their names or emails.
Since you ordered traffic to a third party website, we cannot check if you got any optins/sales. You should be able to check the results of your campaign on the autoresponder connected to your landing page or in your website back office, depending on your setup.
I'd suggest you contact the administrator of your landing page to check if you got any sales/opt-ins.
As per chat conversation, I did try to fill up information on your landing page and you were able to see my email. So your landing page is working.
I don't know how many clicks you ordered but to judge on 19 clicks is too early in my opinion.
