Multiple landing pages

We have a website with interchangeable products and we need to add a field for entering an email next to each product in order to receive a unique coupon in the email. Each product should receive a different coupon depending on the product, And when a user enters his email, he immediately receives an email with a product-specific coupon.
Is there a built-in way and tools to do this in Webflow? If not, what is the right and smart way to do it?
Thanks!
