Mail Designer
Mail Designer is a macOS application for creating professional HTML email newsletters and templates. It offers a drag-and-drop editor with pre-built responsive layout blocks, image libraries, typography options, and mobile preview tools. Users can export emails as HTML, send via SMTP, or use the app's built-in delivery service to distribute newsletters directly. The app is targeted at marketing professionals, small businesses, and teams who need to design visually polished emails without writing code.
AI Recommendation
1 suggestionMail Designer Standard 2 (com.equinux.MailDesignerStandard2) has been discontinued by its developer. No further updates are planned and no native Apple Silicon build exists for this older version. Although it continues to run under Rosetta 2 today, Apple is removing Rosetta 2 in macOS 28 (late 2027), at which point this app will stop launching entirely. If you rely on Mail Designer for your workflow, you should migrate to an alternative email design tool before the deadline. Mail Designer 365, a completely rewritten and actively maintained successor from the same vendor, is now available as a native macOS app with all the modern features (responsive design, mobile optimization, built-in sending and export options, team collaboration) and runs natively on Apple Silicon Macs. That is the recommended path if you want to stay with the Mail Designer family. Alternatively, Mailmodo, Dyspatch, or Stripo are professional email-design platforms with native or web-based support.
