Using Claude Design, Claude Code, and Courier AI to Create a Multichannel Onboarding Series in 30 Minutes

Claude Design, a natural-language design tool launched on April 17, 2026, enables users to create visual mocks and actual React components from descriptions, facilitating the creation of a multichannel onboarding series in just 30 minutes. The process involves using Claude Design for initial channel mocks, which are then turned into templates by the Courier skill, published through the Courier MCP, and tested using the Courier CLI. The onboarding series is composed of four parts, each covering a specific topic and designed to be sent across email, Slack, mobile push, and in-app inbox channels. The templates are integrated into a Courier Journey, allowing for dynamic sequencing based on user events rather than fixed schedules, and are designed to adapt messaging through AI-powered personalization. This efficient approach aims to streamline marketing execution by reducing the need for multiple roles through the use of AI and automation.
