Waypoint Email Builder
What Waypoint Email Builder is
Waypoint Email Builder, also called EmailBuilder.js, is a free, open-source block-based email template builder for developers. Its drag-and-drop editor lets users style blocks and match a brand without writing CSS. Built-in blocks include avatars, buttons, columns, containers, dividers, headings, HTML, images and spacers. The builder outputs JSON or raw HTML for rendering into email markup. Developers can fork the project, self-host it and create custom blocks. The maker says blocks are tested with modern desktop and mobile clients including Gmail, Apple Mail, Outlook, Yahoo Mail, HEY and Superhuman. Examples show rendered HTML sent through Nodemailer, with email APIs such as Amazon SES, SendGrid or Mailgun also usable. EmailBuilder.js is Waypoint’s community version; the hosted product additionally lists API sending, sandbox testing, custom domains, attachments, webhooks and unsubscribe pages.
Who it suits
EmailBuilder.js suits developers who need a self-hosted, extensible visual editor for transactional email templates. It is useful when generated JSON or HTML will be delivered through a separate mail system.
