Closed User Groups: an additional channel for DTC webshops

A Closed User Group (CUG) is a private group of customers, companies, or entrepreneurs who have access to a unique online environment based on membership. This includes groups formed within loyalty platforms that are only accessible behind a login. Examples include member benefit portals, employee associations of KPN or Accenture, and FNV Member Benefits. These groups are ideal for exclusive promotions from A-brands, creating significant value for members.

Consider groups formed within loyalty platforms that are only accessible behind a login. For example, member benefit portals, employee associations of KPN or Accenture, and FNV Member Benefits. These groups are ideal for exclusive promotions from A-brands, creating significant value for members.   

CUGs are a way to generate additional sales through a Direct-to-Consumer (DTC) webshop. With a network of over 250 affiliated Closed User Group partners worldwide, GENRTR offers an effective way to promote and sell products within exclusive, closed communities.   

Benefits of CUGs

  • Higher conversion rates
    Within a CUG, products are often offered with high discounts. Members appreciate unique and valuable promotions, resulting in higher lead and conversion rates.    
  • Unique sales channel
    CUG marketing offers a new sales channel to gain more market share and increase brand awareness. This is particularly interesting for brands with a Direct-to-Consumer (DTC) strategy.   
  • No channel conflict
    The offer is only accessible in a closed environment, which prevents channel conflicts. Since the offer is behind a login, there is no channel conflict with retailers. This makes it possible to make exclusive offers within the CUG without affecting other sales channels.   
  • Higher discounts and lower commissions
    Due to the closed environment, more opportunities are available to offer higher discounts to a specific group, which will lead to increased sales and turnover. Commissions within CUG marketing are typically low, making the Return on Ad Spend (ROAS) often much higher than with other channels.
