Mailjet NodeJs Wrapper

Please welcome the new Mailjet official NodeJS API wrapper!

Mailjet is an Email Service Provider (ESP). Visit the website and get comfortable!

Every code examples can be find on the Mailjet Documentation

(Please refer to the Mailjet Documentation Repository to contribute to the documentation examples)

Getting started

first, create a project folder

mkdir mailjet-project && cd $_


if you want to get a global installation, you can add -g

npm install node-mailjet

Show me the code

To authenticate, go get your API key, and API secret here, open your favorite text editor and import the mailjet module

var Mailjet = require('node-mailjet').connect('api key', 'api secret');

Additional connection options may be passed as the third argument. These values are supported:

  • proxyUrl: HTTP proxy URL to send the email requests through
  • timeout: API request timeout in milliseconds


var Mailjet = require('node-mailjet').connect('api key', 'api secret', {
  proxyUrl: process.env.https_proxy,
  timeout: 60000 // 1 minute

The proxy URL is passed directly to superagent-proxy.

Get cosy with Mailjet

Save your API_KEY and API_SECRET:

echo 'export MJ_APIKEY_PUBLIC=MY_API_KEY' >> ~/.zshrc

echo 'export MJ_APIKEY_PRIVATE=MY_API_SECRET' >> ~/.zshrc

source ~/.zshrc

replace zshrc with bash_profile if you are simply using bash

And use it in your projects

var apiKey = process.env.MJ_APIKEY_PUBLIC,
  apiSecret = process.env.MJ_APIKEY_PRIVATE;

Store a Mailjet resource

// GET resource
var user = Mailjet.get('user');

// POST resource
var sender = Mailjet.post('sender');

Request your resource with a callback function

user.request(function (error, response, body) {
  if (error)
    console.log ('Oops, something went wrong ' + response.statusCode);
    console.log (body);

Make the same request with a Promise

  .then(function (result) {
    // do something with the result
    // result structure is {response: {...}, body: {...}}
  .catch(function (reason) {
    // handle the rejection reason

Pass data to your requests

sender.request({ Email: 'mr@mailjet.com' })

Pass parameters as well as a callback

var getContacts = Mailjet.get('contact');

getContacts.request({Limit: 3}, handleContacts);

Request a resource with an ID


Request a ressource with an Action

var postContact = Mailjet.post('contact');

  ContactLists: MyContactListsArray,
    Contacts: MyContactsArray,
}, handlePostResponse)

Send an Email

var sendEmail = Mailjet.post('send');

var emailData = {
    'FromEmail': 'my@email.com',
    'FromName': 'My Name',
    'Subject': 'Test with the NodeJS Mailjet wrapper',
    'Text-part': 'Hello NodeJs !',
    'Recipients': [{'Email': 'roger@smith.com'}],
  'Attachments': [{
    "Content-Type": "text-plain",
    "Filename": "test.txt",
    "Content": "VGhpcyBpcyB5b3VyIGF0dGFjaGVkIGZpbGUhISEK",


Send two Emails

var emailData = {
    'FromEmail': 'gbadi@student.42.fr',
    'FromName': 'Guillaume badi',
    'Subject': 'Coucou Mailjet2',
    'Text-part': 'Hello World2',
    'Recipients': [{'Email': 'gbadi@mailjet.com'}],

var emailData2 = {
    'FromEmail': 'gbadi@student.42.fr',
    'FromName': 'Guillaume badi',
    'Subject': 'Coucou Mailjet2',
    'Text-part': 'This is another Email',
    'Recipients': [{'Email': 'gbadi@mailjet.com'}],



Have Fun !

var mailjet = require ('./mailjet-client')
    .connect(process.env.MJ_APIKEY_PUBLIC, process.env.MJ_APIKEY_PRIVATE)

function handleError (err) {
  throw new Error(err.ErrorMessage);

function newContact (email) {
      .request({Email: email})

function testEmail (text) {
  email = {};
  email['FromName'] = 'Your Name';
  email['FromEmail'] = 'Your Sender Adress';
  email['Subject'] = 'Test Email';
  email['Recipients'] = [{Email: 'Your email'}];
  email['Text-Part'] = text;


testEmail('Hello World!');

Run Test

npm test
