Basic Example

How to send Mail basic example to get you started with Nodemailer:

In Node & Express Js​

  1. Create a new file named sendEmail.js:

    const nodemailer = require('nodemailer');

    // Create a transporter object
    let transporter = nodemailer.createTransport({
        service: 'gmail',
        auth: {
            user: 'your-email@gmail.com',
            pass: 'your-email-password'
        }
    });

    // Define email options
    let mailOptions = {
        from: 'your-email@gmail.com',
        to: 'recipient@example.com',
        subject: 'Test Email',
        text: 'Hello, this is a test email sent using Nodemailer!',
        html: '<b>Hello, this is a test email sent using Nodemailer!</b>'
    };

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

  2. Run the script:

    node sendEmail.js

In ES6 method​

To use Nodemailer in an ES6 environment, you can take advantage of the modern JavaScript features such as import statements, async/await, and environment variables for configuration. Below is a step-by-step guide:

Step 1: Set Up Your Project​

  1. Configure your project to use ES6 modules: In your package.json, add the following property to enable ES6 modules: 
    {
      "type": "module"
    }

Step 2: Create the Basic Email Sending Script​

  1. Create a file named sendEmail.mjs:

    import nodemailer from 'nodemailer';
    import dotenv from 'dotenv';

    dotenv.config();

    const sendEmail = async () => {
        // Create a transporter object
        const transporter = nodemailer.createTransport({
            service: 'gmail',
            auth: {
                user: your-email@gmail.com,
                pass: your-email-password
            }
        });

        // Define email options
        const mailOptions = {
            from: process.env.EMAIL,
            to: 'recipient@example.com',
            subject: 'Test Email',
            text: 'Hello, this is a test email sent using Nodemailer!',
            html: '<b>Hello, this is a test email sent using Nodemailer!</b>'
        };

        // Send the email
        try {
            const info = await transporter.sendMail(mailOptions);
            console.log('Email sent: ' + info.response);
        } catch (error) {
            console.error('Error sending email: ' + error);
        }
    };

    sendEmail();

  2. Run the script:

    node sendEmail.mjs
