var eml = fs.readFileSync(myFile, "utf-8");


simpleParser(eml).then(parsed => {

  htmlFile = parsed["html"]
  htmlFile = htmlFile.replace(/\\r/g, ''); //This removes all "\r"
  htmlFile = htmlFile.replace(/\\n/g, ''); //This removes all "\n"
  htmlFile = htmlFile.replace(/\\/g, ''); //This removes all "\"

  fs.writeFileSync("emailHtml.html", htmlFile); //Here's your HTML file. You can change the name if you wish
