After the NewsMAN Javascript code is integrated in your eCommerce shop, we expose a simple Javascript API, that you can use to TAG or set a property for an email subscriber or a customer.
_nzm.setProp("key", "value")
For example, you can group all your users who reach a certain page or shop category or blog section from your site. You can even Tag users by how deep they scroll on your page.
Tagging is a real time way to segment your email subscribers list.
