This is a demo showcasing what the Mailchimp Pack can do.
In the demo scenario, we see behind the doc of a small coffee place with a little store. The place has a membership program. Each member has a QR code to scan when he buys something. For each purchase, he gets points that he can use for products.
The store uses Mailchimp to send out monthly newsletters that show new products, but also the current points of the member.
