Twilio Notify, a multi-channel messaging API for delivering notifications through a single interface, will be officially deprecated by the end of 2025, prompting a need for users to migrate their notification infrastructure. Knock is presented as a viable alternative, offering more comprehensive features such as transactional and promotional messaging, native in-product messaging, and audience-based notifications. Unlike Twilio Notify, Knock supports a wide range of communication channels, including SMS, email, push, in-app, and chat platforms like Slack and MS Teams, with additional functionalities like workflow builders, user preference management, and visual template editors. The transition involves mapping Twilio concepts such as identities and bindings to Knock's user IDs and channel properties, with the added advantage of Knock's SDKs and components for easier token management. Knock's structured system allows for better targeting logic and enhanced notification orchestration, providing an opportunity to upgrade the notification stack with improved flexibility and control.
