Mass marketing is dead, because mass personalization through artificial intelligence killed it. Yet few marketers have prepared their organizations to deliver personalized customer experiences at scale in the era of AI. This is especially true in Switzerland. The reason for this is twofold. First, a pervasive and growing fear about data privacy. According to a report by PwC, Swiss consumers are more concerned about data security and data protection than people in the rest of the world. Second, leveraging AI in marketing solutions requires a unified data strategy. But these roadblocks are not a fatality, and some Swiss companies, like Swisscom and Nestlé are leading the way in implementing successful marketing solutions.
