Build beautiful emails with Tailwind CSS and React Email, a set of unstyled components that makes it easy to build modern-looking emails without dealing with old-school HTML and CSS. The integration is made possible by the team's hands-on support and the help of their open source community. A special thanks is given to Vinicius de Moraes for leading the initial implementation and fixing several issues along the way. The integration allows developers to customize the default theme with available properties in Tailwind CSS docs, making it a game-changer for email development.
