npm install sendgrid-nodejs


It can be this easy

var SendGrid = require('sendgrid-nodejs').SendGrid;
var sendgrid = new SendGrid(user, key);
  to: '',
  from: '',
  subject: 'Hello World',
  text: 'My first email through SendGrid'

And you're done!

Digging in

There are two objects that you really need to know to get started:

  • SendGrid
  • Email


Email is the object that will help you easily perpare your message to be sent. To get started create an Email object

var email = new Email(optionalParams);

You can pass in as much or as litle to optionalParams as you want, as the email object has methods for manipulating all of the data.

params structure

var default_mail_params = {
  to: [],
  from: '',
  smtpapi: new SmtpapiHeaders(),
  subject: '',
  text: '',
  html: '',
  bcc: [],
  replyto: '',
  date: new Date(),
  files: {},
  file_data: {},
  headers: {}

Sample for using it:

var email = new Email({
  to: '',
  from: '',
  subject: 'Hey',
  text: 'Did you see that ludicrous display last night?'
Setting data

In general setting a value will override it while adding that value will add it to the existing values but will override existing keys with the new value.

var email = new Email({
  to: '',
  from: '',
  subject: 'Listen',
  text: 'Haved you tried turning it off and on again'
// Add other to addresses 
// addTo also takes an array 
email.addTo(['', '']);
// setHeaders will override any header values already set 
email.setHeaders({customHeader: 'some-value'});
// addHeaders will add to existing headers, overriding existing keys 
email.addHeaders({customHeaderTwo: 'Another value'});
// Adding substitution values 
email.addSubVal('key', value);
// Setting unique args will override any values already set 
email.setUniqueArgs({cow: 'chicken'});
// Adding unique args will add to existing values, overriding existing 
email.addUniqueArgs({cat: 'dog'});
// Setting/Adding a category 
// Setting/Adding a Section 
email.setSection({'-section-': 'text name'});
email.addSection({'-other-': 'person name'});
// Setting a Filter, takes an object literal 
  'footer': {
    'setting': {
      'enable': 1,
      'text/plain': 'You can haz footers!'
// Adding a filter via addFilterSetting 
email.addFilterSetting('footer', 'enable', 1);
email.addFilterSetting('footer', 'text/hmtl', '<strong>boo</strong>');
// Adding a file 
email.addFile('secret.txt', '/path/to/file');

More examples can be find in the test


If you're interested in seeing some sample code or just want to run the test then here's what you need to know. Test written in the test/lib folder can be ran as in and should all pass. Test written in test/intergration need the values in test/test.setup to be set in order to run and will require a SendGrid account, as these test will send actual emails.


make test

will run all tests, otherwise you can run individual tests by running

mocha /path/to/test.test.js
