Best Email Design Software in 2026
Email design software supports the creation and refinement of layouts, whether your workflow centers on visual editing, code, or reusable components. Compared on editor type, custom code editing, and custom fonts, the entries also specify HTML export and reusable content blocks. Included editor seats can matter for shared work, while free plans and paid-from pricing help you evaluate cost. MJML, Mail Studio, and Beefree (now RGE Studio) are among the options shown. Think about how you build email designs, whether you need to move finished HTML elsewhere, and how often you reuse layouts.
