I'm having trouble positioning my product

Hey guys,

Working in a branding agency for a few years now, I've come across multiple projects in the past that required us to build a marketing website together with a form that allowed users to enter their details and redeem a free product sample.

The product sample giveaway mechanics work this way:

1. User visits the site and submits her details.
2. The site sends an email to the user.
3. User visits a physical branch to collect her free product sample using the confirmation email she received as proof (or sometimes the brand ships the sample to user's address).

I recently started working on a SaaS that helps us create those forms with drag & drop together with a backend dashboard we could provide to our clients so that they can manage the data and the fulfillment of the product samples.

I'm keen to put this up online as a service others could use as well, but I'm quite stuck with giving it a name and with writing copy to describe it.

My struggle is that there is a ton of "form builders" and "social giveway campaign tools" out there that are not exactly the same but overlap quite a bit with what I'm working on.

It'd be massive help if you could share your thoughts on any of these questions:

1. Have you ever had a similar use case?
2. What do you call this whole process?
3. Would you ever choose to use a tool like this instead of the generic form builders and the social giveaway platforms out there?

Thank you for reading my long post :)
