Sending Email To Multiple Recipients Via Nodemailer

Sending Email To Multiple Recipients Via Nodemailer

Sending emails to multiple recipients can be an essential feature for many applications, and using Nodemailer, a popular email sending library for Node.js, makes this process straightforward and efficient. In this guide, we will walk you through the steps to send emails to multiple recipients using Nodemailer so you can easily incorporate this functionality into your projects.

Before we dive into the code, make sure you have Nodemailer installed in your Node.js project. You can install it using npm by running the following command in your terminal:

npm install nodemailer

Once you have Nodemailer installed, you can start by creating a new instance of the Nodemailer module in your JavaScript file. Here's a simple example of how you can set up the transporter to send emails:

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport({
  service: 'Gmail',
  auth: {
    user: 'your-email@gmail.com',
    pass: 'your-password'
  }
});

In the code snippet above, we are creating a transporter object that specifies the email service you want to use (in this case, Gmail) and providing your email address and password for authentication.

Next, you can define the email options, including the list of recipients you want to send the email to. To send an email to multiple recipients, you can pass an array of email addresses to the 'to' property in the mailOptions object. Here's an example:

const mailOptions = {
  from: 'your-email@gmail.com',
  to: ['recipient1@example.com', 'recipient2@example.com'],
  subject: 'Hello from Nodemailer',
  text: 'This is a test email sent using Nodemailer.'
};

In the 'mailOptions' object above, we are specifying the sender's email address, an array of recipients, the email subject, and the email content.

Finally, you can use the transporter object to send the email with the defined options. Here's how you can send the email to multiple recipients:

transporter.sendMail(mailOptions, (error, info) => {
  if (error) {
    console.error(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
});

By calling the 'sendMail' method on the transporter object with the 'mailOptions', you can send the email to multiple recipients. If there are no errors, you will receive a confirmation message in the console indicating that the email was sent successfully.

And there you have it! You have successfully sent an email to multiple recipients using Nodemailer. Feel free to customize the email options further based on your requirements to enhance the functionality of your email sending feature. Happy coding!
