We have seen instances where entire regions are cut off from services due to geopolitical reasons, leaving developers and users stranded. Software should be accessible and reliable, regardless of borders. Driven by a passion for open source, I want to provide a truly independent alternative. I am releasing the core of my commercial project, MySigMail Card, to the community to ensure that everyone has access to a powerful, self-hosted email builder. Features - Visual drag-and-drop editor - Component catalog with ready-to-use blocks: Menu , Header , Content , Feature , Call to Action , E-Commerce , Footer - Spot editing with a component tree ( Block - Row - Cell - Atom ) - Atom types: text , button , divider , image , menu - JSON export/import from the UI - Import modes: replace and append - Template validation + sanitization on import - Auto-persist to localStorage and hydration on reload - Preview rendered in Shadow DOM to isolate editor styles Roadmap The original codebase served well for years, but the web has evolved.
