An email design and sending platform that combines AI and React Email

Generate templates with prompts, no complex coding required : Without directly writing HTML or table structures, you can instantly generate stylish email layouts and design elements using only natural language commands (prompts).
Design sophistication based on React Email : Unlike existing WYSIWYG (drag-and-drop) editors with many limitations, it is built on the open-source react-email and Tailwind CSS, allowing you to faithfully implement detailed design system specifications such as typography, padding, and color.
Reduced collaboration effort with developers : Styles created by AI or adjusted in the design editor are immediately converted into clean React code (tsx), significantly reducing design implementation discrepancies and style rework when handing them off to developers.
Real-time multi-device debugging : It provides real-time rendering previews in dark mode, across various email clients (Gmail, Outlook, Apple Mail, etc.), and on mobile screens, enabling you to quickly check for design breakage across devices.
