In their own words
Foundation for Emails
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.
PostBrix
PostBrix is a browser-based email builder for producing responsive templates and organizing assets for campaigns. Its visual editor lets users arrange text, images, buttons, dividers, and columns without writing HTML. Layouts are designed for mobile and desktop, and saved headers, footers, and calls to action can be reused across projects. The product can help generate or refine email copy with AI, then export templates as MJML or fully inlined HTML for an existing workflow. PostBrix says its exported code works with services that accept HTML or MJML, including Mailchimp, HubSpot, SendGrid, Brevo, Postmark, Amazon SES, Klaviyo, Customer.io, ActiveCampaign, and Mailgun. The documentation also describes REST API rendering and key management, live previews, test emails, responsive checks, and rendering troubleshooting. A free plan and free trial are available; paid plans start at $9/mo. The free tier is limited to five monthly exports, five daily downloads, three daily test emails, and ten lifetime AI generations.
