-If we embed the app on our own website, is there a way to force our traffic / users to enter their name & email to gain access to our (your) mockup tool? So only our clients can use it, or perhaps almost like a lead magnet type thing. Trade their email for access to make their own mockups.

-If we did that, can we limit it so X users only get Y number of credits to use, so they dont make 999 mockups everyday & waste them all?

Thanks for the help
