Send Emails From Node.JS Using Sendinblue in Just 5 Steps

In this article, you will learn how to send emails from Node.js with SendInBlue.

What is SendInBlue?

SendInBlue is an email service that allows you to send emails from your Node.js application.

Get the Sendinblue email API key

1. Go to SendinBlue and create an account.
2. Go to Dashboard and click on the top right-hand side.
3. Click on the SMTP & API tab.
4. Click on the Create new API key button.
5. Now we need to store the API key in an environment variable.

Setup

• Install packages:

npm init -y
npm i dotenv sib-api-v3-sdk

• Create a file called .env and add the following lines:

API_KEY=<your_api_key>

• Create a file called index.js and add the following lines:

const Sib = require('sib-api-v3-sdk')

require('dotenv').config()

const client = Sib.ApiClient.instance

const apiKey = client.authentications['api-key']
apiKey.apiKey = process.env.API_KEY

Explanation:

require('dotenv').config(): This is used to load the environment variables from the .env file.

• We need to add the API key to the Sendinblue client.

const tranEmailApi = new Sib.TransactionalEmailsApi()

const sender = {
	email: '[email protected]',
	name: 'Anjan',
}

const receivers = [
	{
		email: '<email address>',
	},
]

Explanation

With tranEmailApi we can send emails.

• The sender's email has to be the email account that you have used for the SendinBlue account.

tranEmailApi
	.sendTransacEmail({
		sender,
		to: receivers,
		subject: 'Subscribe to Cules Coding to become a developer',
		textContent: `
        Cules Coding will teach you how to become {{params.role}} a developer.
        `,
		htmlContent: `
        <h1>Cules Coding</h1>
        <a href="https://cules-coding.vercel.app/">Visit</a>
                `,
		params: {
			role: 'Frontend',
		},
	})
	.then(console.log)
	.catch(console.log)

Explanation:

• You can send emails using the sendTransacEmail method.

• The subject is required.

• You have to pass either textContent or htmlContent to the method. htmlContent will override textContent.

• You can pass parameters to the email content using the paramsobject.

• Run the file and you will see the email that was sent.
