What it is

Foundation for Emails is a free, open-source web framework for creating responsive HTML emails. It is aimed at marketing, promotional, drip campaign, and transactional messages, with designs intended for major email clients including Outlook. The collection includes 11 customizable templates for newsletters, orders, password resets, and welcome messages. Its responsive grid can stack content on small screens and adjust padding and row width for mobile devices. Inky lets developers write tags such as and , which become email table markup. The ZURB Email Stack combines Gulp, Sass, Inky, an inliner, BrowserSync live reloading, and automatic image compression. Panini layouts and Handlebars partials support reusable headers, footers, and other content. The inliner embeds CSS into style attributes, moves media queries into the body, and compresses output. The CSS version is a ZIP download; the Sass version has a build process requiring Node.js. HTML is the listed export format.
