Sending email to multiple recipients via nodemailer

Question

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(); }   }); }); 

Answer 1

nodemailer (v2.4.2) docs say:

to - Comma separated list or an array of recipients e-mail addresses that will appear on the To: field

so you can just do:

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: "*******",     to: maillist } 

Answer 2

As far as I know you will be able to get multiple recipients like this

"[email protected],[email protected],[email protected],[email protected]" 

So why you don't do something like

var maillist = '****.sharma3@****.com, ****.bussa@****.com, ****.gawri@****.com';  var msg = {     from: "******", // sender address     to: maillist,     subject: "Hello ✔", // Subject line     text: "Hello This is an auto generated Email for ...  ✔", // plaintext body     cc: "*******"         //  html: "<b>Hello world ✔</b>" // html body } 

I have already tried and it is working. Furthermore, from my point of view, why you have to worry about "asynchronously" or sending emails 1K times if you have the capability of sending all of them only in once without any complication?

Anyway hope this help, answer your question or it may help somebody else

Surely, my answer can be improved..
