Selling digital customizable event signs?

Hi everyone,

New member here; appreciate everything I’ve learned from the group so far. I’ve done some searching and haven’t managed to find the answer to this yet, and I’m hoping for some help. My wife recently started an Etsy business selling customizable templates for signs and stationary for events like weddings and other special events, and has had reasonable success. We are looking to expand our market to other platforms, and are interested in learning if a product of this type is allowed to be sold on Amazon. The way it is structured, when a customer purchases an item, a code is sent to their email with instructions to access the link which contains the customizable templates (which they can edit through Canva, a template editor site). Their templates can then be taken to a printer and the precise number can be printed/they can choose their own cardstock, etc. I really haven’t seen anyone doing this on Amazon, but I can’t find a great reason why they can’t. I’ve even looked through the Amazon seller terms page and I couldn’t find anything specifically prohibiting the sale of these kinds of items in Amazon’s resources. Any enlightenment would be helpful; please be kind.

Thanks everyone!

TL;DR: my wife owns an Etsy shop selling digital wedding/special event stationery templates and signs; can these types of digital products be sold on Amazon?
