Performance Marketing in
E-Commerce: Goal-Oriented Portfolio Approach Reduces Cost-Revenue-Ratio by 18.5% and Increases ROAS by 22%

Online retailer Flaschenpost.ch optimizes its digital advertising campaigns with the help of the marketing analytics platform Nexoya. The cost-revenue-ratio improved, return on ad spend increased, and the accuracy of performance forecasting reached 99%. Flaschenpost: “We’ve taken efficiency and performance to a new level.”

Zurich and Berlin, April 9, 2025 – Flaschenpost Services AG, the largest online wine retailer in Switzerland, faced the challenge of optimizing its complex multi-channel advertising campaigns while maintaining a strict cost-revenue-ratio (CRR) – in other words, achieving revenue growth without increasing costs. This required a smart, data-driven approach to campaign optimization. As Flaschenpost scaled its digital marketing activities, managing hundreds of products across multiple platforms became increasingly complex. Manually optimizing budgets and tracking performance was time-consuming and limited the team’s ability to respond quickly to changing trends. The solution came through transitioning to an automated, AI-driven process using the marketing analytics platform Nexoya. A key element of this setup was the goal-oriented portfolio approach, which allows campaigns to be optimized based on specific performance objectives – such as maintaining a target CRR or improving return on ad spend (ROAS).

In today’s fast-changing advertising landscape, only those with dynamic, real-time budget allocation across multiple platforms can keep up. The marketing team at Flaschenpost manages a highly complex advertising portfolio, with over 35 campaigns running across Google Shopping, Microsoft Ads, Meta, and Criteo – covering hundreds of products, in four languages, across multiple channels. They were looking for an efficient way to dynamically allocate budgets without compromising performance. The goal was to use both financial and human resources effectively while maintaining a predefined cost-revenue-ratio. The answer to these challenges was an automated, low-effort optimization solution: Nexoya’s AI-powered platform. It enables the optimization of cross-channel digital marketing campaigns by aggregating data from various platforms and continuously monitoring key performance metrics. Based on this data, and using AI and predictive analytics, campaign outcomes can be improved and performance enhanced across all channels.

More Revenue and Profit with Lower Advertising Spend

Performance marketers can choose between two types of portfolio strategies to optimize cross-channel campaigns, each designed to achieve different goals. Budget-based portfolios aim to maximize performance within a predefined budget, while target-based portfolios are focused on reaching specific marketing objectives – such as a certain cost-per-action (CPA) or return on ad spend (ROAS). In the latter, the budget becomes a tool to achieve those performance goals. At Flaschenpost, the marketing team has achieved impressive results since March 2024. Thanks to dynamic campaign optimization, they not only met their targeted cost-revenue-ratio (CRR), but exceeded it: the initial CRR improved by 18.5%. This directly contributed to a stronger ROAS, which increased by over 22% through continuous optimization.

Dominic Blaesi, CEO of Flaschenpost, commented: “Nexoya’s optimization capabilities have truly exceeded our expectations. We’ve achieved results we never thought possible. It has boosted our performance, increased revenue and profit – all while reducing advertising spend. We’ve taken efficiency and performance to a whole new level.”

Marco Hochstrasser, CEO and Co-Founder of Nexoya, added: “Since the beginning of 2025, we’ve been optimizing Flaschenpost’s campaigns based on profit – specifically focusing on POAS, or profit on ad spend, which reflects the gross profit generated per advertising dollar. The target POAS was already surpassed by 9.2% within the first two months. This clearly outperformed expectations and validates the effectiveness of our current strategy. By providing our algorithms with this data, Flaschenpost enables Nexoya to deliver significant added value. Previously, optimization was based solely on ROAS. This marks another important milestone in our partnership – and the results speak for themselves.”

99% Accuracy in Performance Forecasting

The Flaschenpost marketing team benefited from complete data transparency and highly accurate performance forecasting. Nexoya’s model correctly predicted 99% of revenue in the highly volatile wine e-commerce market.

Jason Berglas, Growth Hacker at Flaschenpost, remarked: “The transparency and accuracy of Nexoya’s predictions are remarkable. Seeing how the algorithm continues to improve by learning from our data reinforces our confidence that we’re on the right path to even better results.”

Marco Hochstrasser added: “We typically achieve high forecasting accuracy – but such a strong result is exceptional. It’s a testament to the clean and well-structured data provided by Flaschenpost, which offers the ideal foundation for our algorithms. This combination of high-quality customer data and our AI-powered solution created the perfect match, enabling these outstanding results.”

Nexoya’s Target-Based Portfolio

Optimizing cross-channel performance marketing toward a specific goal remains a significant challenge. In practice, it’s difficult to align campaigns across all channels with a single business objective – often at the expense of budget efficiency. Nexoya’s target-based portfolio changes that. It empowers marketers not only to focus on a core performance goal but also to control the pace at which that goal is achieved. This functionality offers greater flexibility, allowing users to optimize spend efficiently while aligning the speed of goal attainment with business needs. Moreover, portfolio goals can be easily redefined to reflect shifting priorities – ensuring that performance marketing strategies remain adaptable in a dynamic environment.
