HTML Mailer is a Chrome extension designed to enable users to effortlessly insert custom HTML into Gmail emails. This tool is particularly useful for marketers, designers, and individuals requiring consistent branding through beautifully formatted emails. It features a large, distraction-free editor with live previews, allowing users to instantly visualize how their HTML will appear to recipients.
