First, install NodeMailer to your node application

npm install --save nodemailer

After installing in your js file require it

const nodeMailer = require('nodemailer');

Now, create transporter object using the default SMTP transport which can send emails. In this example, I am using ZOHO mail.

let transporter = nodeMailer.createTransport({
            host: 'smtp.zoho.com',
            port: 465,
            secure: true,  //true for 465 port, false for other ports
            auth: {
                user: 'email@example.com',
                pass: 'password'
            }
        });

In auth object specify your email address and password.

Now, we need to configure our email details.

// setup email data with unicode symbols
        let mailOptions = {
            from: '"Your Name" <youremail@example.com>', // sender address
            to: 'abc@example.com, xyz@example.com', // list of receivers
            subject: 'Hello ✔', // Subject line
            text: 'Hello world?', // plain text body
            html: '<b>Hello world?</b>' // html body
        };

Now the last thing is actually sending the email using ‘sendMail()’ method provided by the transporter object we created.

transporter.sendMail(mailOptions, (error, info) => {
            if (error) {
                console.log(error);
                res.status(400).send({success: false})
            } else {
                res.status(200).send({success: true});
            }
        });

‘sendMail()’ method takes two argument mailOptions and a callback function which will be called when the mail is sent. The callback function will be called when either email sent successfully or an error occurred.

Putting everything together,

'use strict';
const nodeMailer = require('nodemailer');
exports.sendMail = function(req,res){
  const transporter = nodeMailer.createTransport({
    host: 'smtp.zoho.com',
    port: 465,
    secure: true,  //true for 465 port, false for other ports
    auth: {
      user: 'email@example.com',
      pass: 'password'
    }
  });
  const mailOptions = {
    from: '"Your Name" <youremail@example.com>', // sender address
    to: 'abc@example.com, xyz@example.com', // list of receivers
    subject: 'Hello ', // Subject line
    text: 'Hello world?', // plain text body
    html: '<b>Hello world?</b>' // html body
  };
  transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
      console.log(error);
      res.status(400).send({success: false})
    } else {
      res.status(200).send({success: true});
    }
  });
}

And that’s how we send emails using NodeMailer.
