Infrastructure for sending and managing cross-channel product notifications.
Knock is a customer engagement platform that provides the infrastructure for product-led growth. It allows teams to ship cross-channel messaging—including email, SMS, push, and in-app—using a developer-first toolkit that features a drag-and-drop editor and powerful APIs.
Knock does not help with AI visibility. Instead, it serves as a customer engagement platform designed to enhance product-led growth by enabling teams to send personalized messages across multiple channels, including email, SMS, and in-app. The productivity gains allow teams to allocate more time to SEO work and content creation.
