What is @sendgrid/mail?
The @sendgrid/mail package is a Node.js client library for sending emails using the SendGrid email service. It provides an easy-to-use interface for composing and sending emails, including support for attachments, templates, and various email options.
What are @sendgrid/mail's main functionalities?
Sending a Simple Email
This feature allows you to send a simple email with a subject, a plain text part, and an HTML part.
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: 'recipient@example.com',
from: 'sender@example.com',
subject: 'Sending with 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>',
};
sgMail.send(msg);
Using Email Templates
This feature allows you to send emails using dynamic templates created on the SendGrid platform. You can pass dynamic data to populate the template.
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: 'recipient@example.com',
from: 'sender@example.com',
templateId: 'd-12345678901234567890123456789012',
dynamicTemplateData: {
name: 'John',
city: 'Denver'
}
};
sgMail.send(msg);
Sending Multiple Emails
This feature allows you to send the same email to multiple recipients with a single API call.
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const messages = [
{
to: 'recipient1@example.com',
from: 'sender@example.com',
subject: 'Hello recipient 1',
text: 'Sending to multiple recipients is easy!'
},
{
to: 'recipient2@example.com',
from: 'sender@example.com',
subject: 'Hello recipient 2',
text: 'Sending to multiple recipients is easy!'
}
];
sgMail.send(messages);
Adding Attachments
This feature allows you to send emails with attachments. The attachment content should be base64 encoded.
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: 'recipient@example.com',
from: 'sender@example.com',
subject: 'Attachment Example',
text: 'Please find the attached file.',
attachments: [
{
content: 'Some base64 encoded content',
filename: 'somefile.txt',
type: 'plain/text',
disposition: 'attachment',
contentId: 'mytext'
}
]
};
sgMail.send(msg);

Installation
Prerequisites
- 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 USE_CASES.md.
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: 'test@example.com',
from: 'test@example.com',
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>',
};
sgMail
.send(msg)
.then(() => {}, error => {
console.error(error);
if (error.response) {
console.error(error.response.body)
}
});
(async () => {
try {
await sgMail.send(msg);
} catch (error) {
console.error(error);
if (error.response) {
console.error(error.response.body)
}
}
})();
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.
