Sending email to multiple recipients via nodemailer

I am trying to send email to multiple recipients. For this I have created an array of recipients, but with my code I am only able to send mail to last email ID of the array three times. What's wrong with my code?

var nodemailer = require("nodemailer");

var smtpTransport = nodemailer.createTransport(
"SMTP",{
  host: '',
  //  secureConnection: true,         // use SSL
  port: 25
});

var maillist = [
  '****.sharma3@****.com',
  '****.bussa@****.com',
  '****.gawri@****.com',
];

var msg = {
    from: "******", // sender address
    subject: "Hello ✔", // Subject line
    text: "Hello This is an auto generated Email for testing  from node please ignore it  ✔", // plaintext body
    cc: "*******"    
    //  html: "<b>Hello world ✔</b>" // html body
}


maillist.forEach(function (to, i , array) {
  msg.to = to;

  smtpTransport.sendMail(msg, function (err) {
    if (err) { 
      console.log('Sending to ' + to + ' failed: ' + err);
      return;
    } else { 
      console.log('Sent to ' + to);
    }

    if (i === maillist.length - 1) { msg.transport.close(); }
  });
});

Your problem is referencing the same msg object from async code. The foreach completes before the sendMail would send out the emails.

So msg.to wil be the last item from the maiilist object.

Try to clone/copy msg inside maillist foreach, or just move msg definition to there :

maillist.forEach(function (to, i , array) {


  var msg = {
        from: "******", // sender address
        subject: "Hello ✔", // Subject line
        text: "Hello This is an auto generated Email for testing  from node please ignore it  ✔", // plaintext body
        cc: "*******"    
        //  html: "<b>Hello world ✔</b>" // html body
    }
  msg.to = to;

  smtpTransport.sendMail(msg, function (err) {
