Supplera: How a German Supplement Brand Builds Customer Loyalty Beyond the Newsletter with the Supplera Club

From one-time buyers to loyal regulars: Supplera uses memberr to run a four-tier cashback program that rewards repeat purchases and keeps customers coming back to their own store.

Supplera stands for high-quality nutritional supplements, carefully manufactured in Germany, with a 100-day satisfaction guarantee and a clear message: when efficacy matters. The brand has built a loyal customer base with a wide product range centered around magnesium, vitamins, and micronutrients.

Customer retention had primarily run through the newsletter channel. That worked, but what was missing was a structured program giving customers a concrete reason to return directly to supplera.de on their next purchase rather than drifting to a competitor.

Together with memberr, the Supplera Club was developed: a four-tier loyalty program with 5% cashback on every order, seamlessly integrated into Shopify and Klaviyo, and launched quickly.

Four Tiers - from Bronze Member to Platinum Status

The Supplera Club is divided into four levels: Bronze, Silver, Gold, and Platinum. Every customer qualifies automatically based on their annual spend.

  • Bronze (from €1): 5% cashback per order, €2 for text reviews, €3 for photo and video reviews, €10 for every successful referral, and access to the exclusive Supplera knowledge base.
  • Silver (from €151): Additionally, early bird access to promotions and €5 birthday credit.
  • Gold (from €401): All health webinars at 25% discount, access to the exclusive Supplera community, and 2 free Q&A webinars per year.
  • Platinum (from €1,601): All webinars free of charge plus VIP handling.

Seamless Integration with Shopify and Klaviyo

A key criterion when choosing memberr was ease of integration. The program embeds into Shopify in just a few clicks and fits seamlessly into existing Klaviyo flows.

Customers automatically receive emails when credit is unlocked, when their balance has not yet been redeemed, or when their birthday is approaching. This makes memberr not just a loyalty tool, but an active part of the entire retention strategy.

Store Credit Visible on the Product Page

Customers can already see on the product page how much store credit they will earn with a given purchase. For a B-complex at €25.49, the note "You will receive €1.27 store credit when purchasing this item" appears directly below the add-to-cart button.

This makes the value of the program tangible at every touchpoint - before the customer even reaches checkout - and increases the likelihood that they will return.

How to collect store credit at Supplera

Redeem with a Toggle - Directly in the Cart and Checkout

Accumulated credit is displayed transparently in the cart and can be activated with a single toggle. No voucher code, no separate step. The credit is immediately deducted from the total and is also visible in checkout as its own payment option.

The experience is intuitive and creates zero support overhead for the store.

Birthday, Reviews, Referrals - More Than Just Cashback

In their account, Supplera customers can see their current credit balance, their personal referral link, and the option to save their birthday.

  • For every referral, the referring customer receives €10 credit; the referred friend gets €10 off their first purchase.
  • On their birthday, customers automatically receive €5 in credit.
  • Review incentives: €2 for text reviews, €3 for photo or video reviews.

This creates a complete retention system that goes far beyond a simple order history.
