    Mail Service for the SendGrid v3 Web API

    This is a dedicated service for interaction with the mail endpoint of the SendGrid v3 API.



    • Node.js version 6, 8 or >=10
    • A Twilio SendGrid account, sign up for free to send up to 40,000 emails for the first 30 days or check out our pricing.

    Obtain an API Key

    Grab your API Key from the Twilio SendGrid UI.

    Setup Environment Variables

    Do not hardcode your Twilio SendGrid API Key into your code. Instead, use an environment variable or some other secure means of protecting your Twilio SendGrid API Key. Following is an example of using an environment variable.

    Update the development environment with your SENDGRID_API_KEY, for example:

    echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
    echo "sendgrid.env" >> .gitignore
    source ./sendgrid.env

    Install Package

    The following recommended installation requires npm. If you are unfamiliar with npm, see the npm docs. Npm comes installed with Node.js since node version 0.8.x, therefore, you likely already have it.

    npm install --save @sendgrid/mail

    You may also use yarn to install.

    yarn add @sendgrid/mail

    Verify Sender Identity

    Verify an email address or domain in the Sender Authentication tab. Without this you will receive a 403 Forbidden response when trying to send mail.

    Quick Start, Hello Email

    The following is the minimum needed code to send a simple email. Use this example, and modify the to and from variables:

    For more complex use cases, please see

    const sgMail = require('@sendgrid/mail');
    const msg = {
      to: '',
      from: '', // Use the email address or domain you verified above
      subject: 'Sending with Twilio SendGrid is Fun',
      text: 'and easy to do anywhere, even with Node.js',
      html: '<strong>and easy to do anywhere, even with Node.js</strong>',
      .then(() => {}, error => {
        if (error.response) {
    (async () => {
      try {
        await sgMail.send(msg);
      } catch (error) {
        if (error.response) {

    After executing the above code, you should have an email in the inbox of the recipient. You can check the status of your email in the UI. Alternatively, we can post events to a URL of your choice using our Event Webhook. This gives you data about the events that occur as Twilio SendGrid processes your email.
