WYSIWYG newsletter editor with PDF generation and a library of responsive templates.
Professional newsletter editor: drag-and-drop WYSIWYG, library of responsive blocks, client preview (mobile, dark mode), and one-click HTML + PDF exports. Built for marketing teams who want to industrialize their editorial production without depending on a designer for every send. Newsletters are tested against major clients (Gmail, Outlook, Apple Mail) via a built-in linter that flags incompatibilities before sending.
Producing a newsletter that renders correctly on Gmail, Outlook and Apple Mail remains a headache. WYSIWYG editors on the market either limit customization or generate broken HTML on Outlook. Marketing teams waste hours in back-and-forth with their designer.
Drag-and-drop editor built in React with a library of blocks validated across major mail clients. HTML rendering is server-side with Outlook fallbacks (VML for buttons, nested tables). A linter catches pitfalls (unsupported media queries, forbidden CSS properties) before export. PDF generation via Puppeteer for print versions or archives. Dark mode tested through simulated preview. Template API to reuse validated blocks across campaigns.
