GrapesJS Newsletter
1 pluginNewsletter plugins turn GrapesJS into a drag-and-drop HTML email builder. They add email-safe blocks — single-column, two-column, header, footer, button, image — and handle inline style application automatically on export, outputting HTML that renders correctly in Gmail, Outlook, and Apple Mail. Some plugins lock the canvas to a 600px fixed width and disable web-only CSS features to prevent users from creating email-incompatible designs. If you are building a newsletter editor for your SaaS or adding email design functionality to an existing product, this collection has the most production-ready options.
