How to Send an Email Using Nodemailer

How to Send an Email Using Nodemailer

If you want to send an email using Nodemailer, follow these steps:

Step 1: Install Nodemailer

Begin by installing Nodemailer using npm:

1
npm install nodemailer

Step 2: Import Nodemailer

Next, import the Nodemailer module in your Node.js script or application:

1
import nodemailer from 'nodemailer';

Step 3: Initialize the Transporter

Create a transporter object that will be used to send the email. Here’s an example:

1

const transporter = nodemailer.createTransport({
 host: 'smtp.yoursmtpserver.com',
 port: 465,
 secure: true,
 auth: {
 user: 'smtp_user',
 pass: 'smtp_pass',
 },
});

⚠️ NOTE: Make sure to replace 'smtp_user' and 'smtp_pass' with the actual credentials of your SMTP server.

Step 4: Create the Email Options

Now, create an options object to specify the details of the email you want to send:

1

5
6
const options = {
 from: '[email protected]',
 to: '[email protected]',
 subject: 'Hi!',
 html: '<p>Hello</p>',
};

Step 5: Send the Email

Finally, use the sendMail() method on the transporter object to send the email. Pass the options and a callback function that will be executed when the email is sent:

1

3
4
5

7
transporter.sendMail(options, (err, info) => {
 if (err) {
 console.log(err);
 } else {
 console.log('EMAIL SENT');
 }
});

Alternatively, you can use the promise-based syntax:

1
const info = await transporter.sendMail(options);

 port: 465,
 secure: true,
 auth: {
 user: 'smtp_user',
 pass: 'smtp_pass',
 },
 });

 const options = {
 from: '[email protected]',
 to: '[email protected]',
 subject: 'Hi!',
 html: '<p>Hello</p>',
 };

 transporter.sendMail(options, (err, info) => {
 if (err) {
 console.log(err);
 } else {
 console.log('EMAIL SENT');
 }
 });
}

That’s it! You now know how to send an email using Nodemailer.
