This might be a minor comment, but I noticed you guys are using Node.js with Express.js to render nodemailer.com. You can (and maybe should) change the favicon from the default Express.js favicon. You can do so by removing `app.use(express.favicon());` from the generated app.js file. At the very least, you could add your own favicon in your public/ folder to make the project page look (albeit in the most vain sense) more polished.
