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

A good way to do it asynchronously would be to use the each function in the async module: https://caolan.github.io/async/docs.html#each

var async = require("async");

async.each(maillist, function(to, callback){

    msg.to = to;

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

    //Do other stuff or return appropriate value here
});
