Let’s code.

Sending your first email :

Head over to your terminal and run the following

mkdir sending-email-sendgrid
cd sending-email-sendgrid
npm init --y

Let’s install the following packages

yarn add dotenv @sendgrid/mail

Open your code editor and create .env file with following content

SENDGRID_API_KEY=<PASTE THE CREATED KEY>

Create index.js file and paste the following

const mail = require('@sendgrid/mail');
const dotenv = require("dotenv")

dotenv.config()
mail.setApiKey(process.env.SENDGRID_API_KEY);

const msg = {
  to: 'to@example.com',
  from: 'from@example.com', // Use the email address that you verified during creation of your sender identity
  subject: 'Sending my first email with Node.js',
  text: 'Email with Node js and Sendgrid',
  html: '<strong>hello world</strong>',
};

(async () => {
  try {
    await mail.send(msg);
        console.log('mail sent')
  } catch (error) {
    console.error(error);

    if (error.response) {
      console.error(error.response.body)
    }
  }
})();

What the above code does

  1. Importing the sendgrid/mail sdk which is helpful for sending the email and configuring the dotenv package to access the environment variables inside our node application.
  2. Configuring both sendgrid and dotenv package.

    Prepping the email to send. In here for the to section use the email which you verified during the sender creation

  3. Finally using send method to send the mail to the user.

Open your terminal and run the following

node index.js

You should see mail sent on your console. Head over to the email to check for the same.

Note: Check the spam folder if the email is not in your inbox
