html2email

html2email helps freelancers and solo marketers create and send professional HTML emails from Gmail, Yahoo, Mail.ru, or Yandex Mail. Users can choose a built-in template, paste or upload HTML, edit it in a visual editor, and save customized templates for reuse. The extension inserts formatted HTML into the compose window with one click and can capture the body of an HTML email into the editor. Its checks flag doctype, preheader, table layout, alt text, and other issues, while the link checker tests URLs for 404s and supports inline UTM edits. Inbox previews show light and dark mode rendering, with an option to download a PNG for client approval. By keeping editing, validation, previewing, and sending in the email client, html2email helps users prepare client-ready messages without switching to another email tool.
