Sending emails using Mailgun with NodeMailer package

Question

A couple of days ago I realized that Google has changed the security of gmail accounts, particularly for the possibility of sending emails from applications. After Googling around for a while I couldn't find a fix for it. So, I resorted to using Mailgun. I created an account and had it enabled with Business verification. However, I still can't send emails. I keep getting an error about the requested URL not being found. I am suspecting that since I haven't set up a domain yet, it is not picking the mailgun domain it provided by default. Could someone show me how to test sending emails using Mailgun from NodeMailer indicating the sandbox name provided by mailgun.

thanks in advance José

Answer 1

I created the Nodemailer transport for mailgun.

Here it how it works.

You install the package with npm install as you would do with any package, then in an empty file:

var nodemailer = require('nodemailer');
var mg = require('nodemailer-mailgun-transport');

// This is your API key that you retrieve from www.mailgun.com/cp (free up to 10K monthly emails)
var auth = {
  auth: {
    api_key: 'key-1234123412341234',
    domain: 'sandbox3249234.mailgun.org'
  }
}

var nodemailerMailgun = nodemailer.createTransport(mg(auth));

nodemailerMailgun.sendMail({
  from: '[email protected]',
  to: '[email protected]', // An array if you have multiple recipients.
  subject: 'Hey you, awesome!',
  text: 'Mailgun rocks, pow pow!',
}, function (err, info) {
  if (err) {
    console.log('Error: ' + err);
  }
  else {
    console.log('Response: ' + info);
  }
});

Replace your API key with yours and change the details and you're ready to go!
