Sending emails with Node.js is very easy using Nodemailer. Nodemailer provides several methods to send emails, but in this tutorial, I will explain how you can do it using your own email account. You can also refer to the Nodemailer documentation to explore different ways to send an email.

Step 1: Intall Nodemailer

First, install the nodemailer package using npm: 

npm install nodemailer

Watch Video for more clarity

Step 2: Write the code

Here's a simple example that shows how to send an email 

const nodemailer = require('nodemailer');

// Create a transporter using Gmail service
const transporter = nodemailer.createTransport({
    service: 'gmail',
    secure: true,
    auth: {
        user: "codewithdeepak.in@gmail.com", // your email
        pass: "ywfknfrzpiswfbwo" // your app password (not your normal Gmail password)
    }
});

// Create the email message
const message = {
    from: "Learn From Codewithdeepak.in",
    to: "codewithdeepak.in@gmail.com",
    subject: "Learn How to Send Email Through Node.js Code",
    html: "
We are learning from Deepak Chaudhary
"
};

// Send the email
transporter.sendMail(message, (error, info) => {
    if(error){
        console.log(error);
    }else{
        console.log("Email sent: " + info.response);
    }
});

✅ What’s Happening Here?

  1. We import Nodemailer and create a transporter using Gmail’s SMTP service. There are several ways to send email you can refer this
  2. We define the email content (from, to, subject, and HTML body).
  3. We call sendMail() to send the email, and check if there’s an error or success.

📌 Final Tip

If you’re using Gmail, make sure you generate an App Password from your Google Account (under Security > App Passwords) and use it instead of your main password.
