About the Knock

Knock is a developer-first platform that provides robust infrastructure for building and managing product and customer notifications. It allows engineering and product teams to integrate multi-channel messaging (email, SMS, in-app, Slack, Microsoft Teams, WhatsApp, etc.) into their applications with a single API. Knock simplifies complex notification workflows, transactional messaging, lifecycle marketing, and one-time announcements, eliminating the need to build and maintain an in-house notification system. Key features include workflow builders, dynamic message templating (using Liquid), recipient preference management, real-time activity logs, and integrations with various communication providers. It aims to accelerate development cycles, improve user engagement, and ensure consistent, personalized communication across all touchpoints.
