Mail about a product

I'm using Hikashop on one of my clients websites - CT-Watches . He's not using the cart-functions, but he want's a mail link on each product. The mail-topic should be the product name. Is this possible? Or any ideas how to make it?

I can see a feature under Configuration that says: "Display a contact button on the product page - Only in commercial versions of HikaShop". Maybe it's new in version 1.0? What does it do?

That's indeed the option you're looking for. That will display a contact button of the product page so that the user can access a contact form, enter some information and send it to you. You will then receive an email with the product page and the information of the user.

That option is only available in the Business and Essential editions of HikaShop. You're apparently using the Starter edition.
So you will have to upgrade your website in order to use that feature.
