Send an email with SendGrid in Node.js

This is an example of how to send an email. To run this script you should:

1. Download the index.js and package.json files
2. Install the dependencies with npm install
3. Get a SendGrid API key from your SendGrid dashboard
4. Verify an email address or authenticate a domain so that you can send emails with SendGrid
5. Set the credentials and other variables in the environment and run the script:

SENDGRID_API_KEY=xyz789 \
  FROM_EMAIL=my_verified_email@domain.com \
  TO_EMAIL=myemail@provider.com \
  node index.js

Alternatively, you can replace the calls to process.env with your variables.

Run the script and you will receive an email.

index.js

const sendgrid = require("@sendgrid/mail");
sendgrid.setApiKey(process.env.SENDGRID_API_KEY);

function sendEmail(from, to, subject, body) {
  sendgrid
    .send({ from, to, subject, text: body })
    .then(() => {
      console.log(`Email sent from ${from} to ${to}`);
    })
    .catch((error) => {
      console.error(error);
    });
}

sendEmail(
  process.env.FROM_EMAIL,
  process.env.TO_EMAIL,
  "Email notification!",
  "This is an email notification!"
);
