What is SendInBlue?

SendInBlue is a mail service that allows you to send emails from your Node.js application.

Get the Sendinblue email API key

Go to SendinBlue and create an account.
Go to Dashboard and click on the top right-hand side dropdown.
Click on the SMTP & API tab.
Click on the Create new API key button.
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. Then we have to add the api key to the Sendinblue client.

const tranEmailApi = new Sib.TransactionalEmailsApi()

const sender = {
    email: 'thatanjan@gmail.com',
    name: 'Anjan',
}

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

Explanation: With tranEmailApi we can send emails. The sender email has to be the email account that you have used in 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 params
object.
Run the file and you will see the email was sent.

node index.js
