It automates the process of collecting, cleaning, and synthesizing data, empowering marketers to make informed business decisions. The platform provides out-of-the-box tools that allow for a consistent data schema, clarifying naming conventions to work with in systems like Ninetailed or Contentful. Twilio Segment handles a staggering trillion customer data points every year and assesses this data to ensure it matches expected events. A CDP like Twilio Segment enables businesses to create personalization efforts by providing marketers with tools to better understand and leverage their data, including real-time identity resolution and complete, trusted customer profiles. The integration of Ninetailed, a personalization and experimentation engine, with Contentful, a content management system, bridges the gap between upstream sources and the content management system, enabling authors to work with rich information about customers and drive compelling experiences based on their understanding of their customers.
