Webfreeglobal

VMail is a free, open-source Progressive Web App that checks the HTML and CSS markup of an email template against known email client support, flagging elements that specific clients like Outlook or Gmail don't fully support. It's aimed at email marketers and developers who need to verify an HTML email will render correctly across clients before sending it.
