Iterable Launches Fall Release with Nova Agents, RCS

Iterable, an AI-powered customer engagement platform, announced a major Fall Product Release featuring native RCS messaging, WhatsApp integration, an Integrations Hub, Salesforce Sync, Journeys Live Data, and new Nova Intelligence Agents. These features aim to unify customer context across the marketing stack, enabling a continuous learning loop where every interaction informs future decisions. The release addresses the 'context gap' by connecting fragmented customer data, conversations, and behaviors. Early adopters report significant gains: Babylist reclaimed 50% of its CRM team's campaign bandwidth, and Send Time Decisioning users see over 70% lift in clicks and 80% in opens. The update marks a shift from AI that assists to intelligence that continuously learns from every engagement.
