Knock's recent launch week introduced a series of updates and new features to enhance cross-channel messaging and developer experience. Day 1 saw the introduction of the Agent Toolkit and MCP server, which empower AI agents with enhanced notification capabilities, enabling them to manage messaging workflows without integration code. Day 2 unveiled Workflows 3.0, featuring a redesigned template editor and workflow canvas aimed at improving speed and usability for engineering, product, and marketing teams. A new broadcast feature allows for one-time messages across any channel, and changes to the preferences model introduce commercial preferences and a 1-click unsubscribe option. Day 4 focused on overhauling Knock's documentation and releasing new SDK versions in multiple programming languages, adding features like retries and advanced logging. Additionally, new guides were introduced to support in-product messaging, granting engineering teams control over message rendering and allowing product and marketing teams to manage and test content effectively. The launch was driven by customer feedback, with Knock inviting ongoing input to guide future developments.
