EmailBuilder.js review
A flexible self-hosted email editor with visual blocks, code output, and extensibility.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
EmailBuilder.js is a free, open-source email template builder for developers and teams creating transactional and product emails. Its drag-and-drop editor uses blocks for text, buttons, images, columns, HTML, and dividers, while style controls support editing individual blocks. The project is available through Waypoint’s hosted playground or can be self-hosted from its public source repository.
Its strongest fit is for teams that need control over how email templates are represented and delivered inside their own applications. EmailBuilder.js produces both JSON and raw HTML email output, making it suitable for workflows that store structured templates, render them in an application, or pass email-ready markup into a delivery system. Custom block extensibility also gives developers a way to adapt the editor beyond its built-in content blocks, although that work requires development effort.
The product’s platform model is a practical advantage for teams that want an open-source foundation rather than a hosted-only editor. Self-hosting supports deployment within an existing application environment, while the hosted playground offers a separate way to work with the builder. Rendering support for major email clients and devices is relevant for teams concerned with template compatibility. EmailBuilder.js is a strong choice for developers who want a free, extensible editor with JSON and HTML output; teams seeking a broader campaign-management system or a fully managed email platform should choose a product built around those needs instead.
