VisitMail Studio suits people creating emails who want drag-and-drop editing with reusable blocks, custom code access, or HTML export. It runs on Linux, macOS, and Windows.
MJML suits developers who prefer a code-first way to create responsive email HTML and want to use reusable components. It is less suited to users expecting the markup tool itself to send rendered emails.
