What Flekki is
Flekki is a free, open-source drag-and-drop editor for creating responsive HTML email templates. The web editor lets you start from a blank canvas or customize a prepared template, then arrange text, images, buttons, dividers, and columns while seeing changes in real time. Flekki says the resulting emails adapt to different screen sizes and can be exported as production-ready responsive HTML for Gmail, Outlook, Apple Mail, and other email platforms. Headers, footers, and content blocks can be saved as reusable segments for later templates. No account or credit card is required, and work is stored locally in the browser. The maker describes the core editor as free without hidden fees or usage limits. Flekki is also available for self-hosting, and its source can be inspected or used as the basis for suggestions. The Free plan is listed as free, with no usage limits and no credit-card requirement.
