What is an HTML email builder?
An HTML email builder is a visual tool that allows users to design email templates using drag-and-drop components while automatically generating the underlying HTML code.
Traditional email design requires knowledge of HTML, CSS, and the quirks of different email clients. An HTML email template builder removes this complexity by providing a visual interface where you design emails the same way you would edit a document.
The builder generates inline-styled HTML intended for Gmail, Outlook, Apple Mail, and mobile email apps. Preview and test your design in your target clients. It uses responsive breakpoints, table-based layouts for Outlook compatibility, and inline CSS — all behind the scenes.
Whether you are building a newsletter, promotional email, or transactional template, an HTML email builder lets you focus on design and content while the technology handles the code.
