javascript - Hide other reciepient in to address while sending email using nodeemailer -

i working on emailsender project using node.js. found nodeemailer package making easier.

but when sending email multiple contacts , contact seeing other contact addresses in column.

i want hide others receiver. receiver see email address only.

the code using is,

var mailoptions = {         from: 'sender@sender.com', // sender address         to: 'reciever1@domain.com,reciever1@domain.com', // list of receivers         subject: 'hello', // subject line         text: 'hello world', // plaintext body         html: '<b>hello world</b>' // html body     };     transporter.sendmail(mailoptions, function(error, info) {         if (error) {         res.send(error);         } else {             res.send('message sent: ' + res);         }     }); 

the question when receiver1 gets email, should not know receiver2 got same email.

thanks.

store listofrecipients in array , loop through them

var listofrecipients = ["reciever1 <reciever1@domain.com>", "reciever2 <reciever2@domain.com>"] (var = 0; < listofrecipients.length; i++) {      var mailoptions = {         from: 'sender <sender@sender.com>', // sender address         to: listofrecipients[i], // list of receivers         subject: 'hello', // subject line         text: 'hello world', // plaintext body         html: '<b>hello world</b>' // html body     };     transporter.sendmail(mailoptions, function(error, info) {         if (error) {             res.send(error);         } else {             res.send('message sent: ' + res);         }     }); }
