使用此代码我必须发送电子邮件吗？我在这里使用AWS smtpTransport，如何在代码中实现“打开”和“单击”事件？请给我一个解决方案？

 var nodemailer = require('nodemailer');
    var smtpTransport = require('nodemailer-smtp-transport');

    var transport = nodemailer.createTransport(smtpTransport({
      host: 'email.amazonaws.com',port: 465,secure: true,auth: {
        user: 'akd',pass: 'BNf'
      }
    }));

    var mailOptions = {
      from: 'samplet213@gmail.com',// sender address
      to: 'mee@gmail.com',// list of receivers
      subject: 'Hello',// Subject line
      text: 'Hello world',// plaintext body
      html: '<b>Hello world</b>' // html body
    };

    transport.sendMail(mailOptions,function(error,info) {
      if (error) {
        console.log(error);
      }
      else{
        console.log('Message sent: ' + info.response);
      }
    });
