In this episode of Customer Journey with Fexingo, Lucas and Luna drill into a specific, often-overlooked touchpoint: the point where a customer updates their profile or preferences. Using the example of a B2B SaaS company, they reveal how a single form field change can cascade into dirty data across CRM, marketing automation, and analytics. They discuss why most journey maps assume clean data inputs, how a misaligned dropdown menu caused a 12 percent drop in email engagement for one real firm, and what a 'data hygiene audit' looks like in practice. Lucas shares a simple fix: adding a timestamp and version history to every profile field change. Luna pushes back with the cost of implementation, and they land on a pragmatic framework for balancing data accuracy with user experience. This episode is essential for marketers, product managers, and anyone who builds customer journeys on top of messy data.
