Yes, it's pretty easy.
I recommend a service like Convertri or ConstantContact which will allow you to drag and drop create a form for users to enter their information into.
After that, have the final form action redirect to your offer.
Do you mean is it technically possible, or legally possible?
Technically, the answer is yes.
Legally, it would depend on your jurisdiction. In those jurisdictions who follow GDPR, for example, the answer is no.
