            Ethereal is a fake SMTP service, mostly aimed at Nodemailer and EmailEngine
            users (but not limited to). It's a completely free
            anti-transactional email service where messages never get delivered.
        
        Instead, you can generate a vanity email account right from Nodemailer, send an email using that account just
            as you would with any other SMTP provider and finally preview the sent message here as no emails are
            actually delivered.
