Gartner defines communications platform as a service (CPaaS) as a cloud-based platform that enables businesses to embed a range of communications capabilities into applications over channels such as voice, SMS, email, messaging apps, and video. They also provide conversational capabilities, security, authentication, and automation. CPaaS delivers omnichannel, programmable experiences to enhance digital customer engagement. In 2026 and beyond, CPaaS aims to offer deeper capabilities, such as customer journey analytics, automation, personalization, and omnichannel engagement driven by AI and 5G. The purpose of CPaaS is to enable enterprises to enhance their communication workflows by providing simplified access to multiple communication capabilities without requiring the complex architectures typically needed to leverage these channels. CPaaS enables enterprises to shorten the time to market for new products and services, personalize communications, and orchestrate customer journeys across multiple channels. It delivers digital engagement and operationalizes customer experience, while also driving business efficiencies at scale with digital service delivery. It is modular/composable in design and can expand from initial single use cases to many others as additional business units learn of its value.
Gartner defines multichannel marketing hubs (MMHs) as software applications, primarily delivered as SaaS, that orchestrate personalized campaigns and event-driven customer journeys across marketing channels. These applications leverage customer data, predictive models and real-time insights to optimize the timing, channel and content of interactions. MMHs apply advanced analytics, AI and prescriptive intelligence to help marketing and technical teams manage the end-to-end life cycle of customer journeys. Although MMHs overlap with customer data platforms (CDPs) and personalization engines, their primary focus is enabling marketing users to manage large-scale consumer interactions, particularly in owned media channels such as email and app push. Multichannel marketing hubs empower marketers to deliver personalized media and orchestrate customer journeys, thus driving revenue, engagement and loyalty. These SaaS applications unify customer data, predictive insights and real-time decision making to optimize interactions across digital channels. MMHs enable multidisciplinary teams to manage campaigns and event-driven journeys via advanced analytics, artificial intelligence/machine learning (AI/ML) and prescriptive intelligence.
