Meet Karen Herzog

Karin Herzog is an award-winning Swiss luxury skincare brand, known worldwide for its pioneering oxygen-activated anti-aging formulas.

With a strong reputation among celebrities, royalty, and high-end spas, the brand’s products—like the Oxygen Face Cream and the Vita-A-Kombi range—are lauded for their medical-grade ingredients and luxurious skincare benefits. 

However, when the brand officially launched in Australia in 2025, it faced the daunting task of entering one of the world’s most competitive skincare markets.

The challenge

Although the brand had already gained experience in the U.S. market over the past five years, entering a completely new and highly saturated market like Australia came with its own set of hurdles. 

Skincare is a crowded space, dominated by well-established household names and fast-moving indie brands. Building trust in this kind of environment takes time, especially for a niche brand that blends science with luxury. 

To overcome initial skepticism, Karin Herzog had to invest heavily in education and storytelling to communicate their unique value.

Additionally, gaining fast traction was crucial. The brand needed to acquire customers and build awareness quickly. 

One of the biggest obstacles? 

They didn’t have a local email list. That meant starting from scratch to grow a subscriber base and create a pipeline of potential customers.

The solution

Karin Herzog partnered with Ecommerce Boost, a retention marketing agency working with 300+ global brands. Together, they built a launch strategy powered by OptiMonk to drive rapid growth.

1. Mystery discount popup

First, they introduced a new mystery discount popup on the website to tap into consumers’ love of surprise offers. 

The call-to-action button, simply labeled “Unlock Discount,” asked for nothing upfront, which lowered friction and sparked curiosity.

This yes/no style popup gave users control so they could choose whether to engage without feeling pressured. Since no personal information was initially requested, visitors were far more likely to interact. 

Once intrigued, they became more open to sharing their details in the next step.

The popup also showcased a luxury-branded design, complemented by social proof, referencing high-end magazines like Vogue, Elle, and Glamour to reinforce the brand’s premium image.

Mystery discount

The sign-up process was split into two steps—a smart move. First, they asked visitors for their email address.

Then, to activate the discount, they were prompted to enter their first name and phone number. 

Final step

This step-by-step approach made the process feel less intrusive, increasing the likelihood that visitors would complete it, especially when the reward felt exclusive and enticing.

2. Smart welcome flow

Thanks to the seamless OptiMonk integration, every new subscriber was automatically funneled into Karin Herzog’s email marketing platform, eliminating the need for manual work.

From there, subscribers were welcomed into a tailored email sequence that introduced the brand’s Swiss roots and the science behind its oxygen-powered skincare. 

Each email combined elegant, luxury-focused design with conversion-boosting elements like bold CTAs and mobile-friendly layouts.

The result? A smooth journey from education to purchase, delivered flawlessly across every device.
