The document discusses the risks of using multiple vendors for customer engagement strategies. It notes that over half of marketers surveyed use at least 6 channels and 21% use over 10 channels. Managing many vendors takes a significant amount of time, around 15 hours per week for some marketers. There are also inefficiencies that arise from technology disconnects between vendors, additional human resources needed to manage errors, and more time spent coordinating vendors than focusing on the customer experience. The document recommends using a single vendor that can integrate essential marketing elements like data analytics, direct marketing, contact centers, social media, ecommerce and fulfillment to reduce costs and inefficiencies and allow more focus on customers.
