Templatical

Open source drag and drop email editor SDK for embedding framework neutral email template creation inside apps.

About Templatical

Templatical is an open source drag and drop email editor SDK built for developers who want to embed email template creation inside their own applications. It is designed to work across React, Svelte, Angular, Vue, and vanilla JavaScript, making it suitable for teams that need a framework neutral email builder.

The product is TypeScript first and built on MJML. It supports JSON templates, MJML output, custom blocks, full theming, merge tags, display conditions, design tokens, dark mode, and style isolation through Shadow DOM. Templatical also highlights zero telemetry, which is useful for teams that want more control over how editor usage and user data are handled.

Templatical can be added to an application with one init() call. The official installation documentation lists packages such as @templatical/editor, @templatical/renderer, @templatical/quality, @templatical/media-library, and @templatical/types. Templatical Cloud is also planned as a hosted layer with AI assistance, MCP integration, real time collaboration, comments, media library, template scoring, multi tenancy, and headless API access.
