Automatic spam filtering.
High deliverability rates to inboxes.
Scales to send millions of emails per month.

Nodemailer on the other hand is just a Node.js module that makes it easy to integrate with various email transports, like an SMTP server. With Nodemailer you still need to bring your own mail server or use a 3rd party provider. Benefits include:

Lightweight and zero dependencies.
Use any SMTP server for delivering emails.
Flexibility to switch between transports easily.
Easy to mock/test emails in development.

So in summary:

Mailgun handles all the complexity of email delivery for you with a robust hosted API. Easy to integrate and send with, great analytics, deliverability and scale.
Nodemailer is just a helper module with no delivery capabilities on its own. You bring the SMTP server/credentials. Flexible transport options but more hands-on configuration required.

Typically if you don't want to manage your own email server infrastructure, Mailgun is the easiest end-to-end email delivery solution. But Nodemailer can make sense if you already have SMTP credentials you want to reuse, or want maximum flexibility over mail transport.

Mailgun npm Example

Here is a simple example sending an email with the mailgun-js package:

const apiKey = 'YOUR_API_KEY'; 
const domain = 'YOUR_DOMAIN_NAME';
const mailgun = require('mailgun-js')({apiKey, domain});

const data = {
  from: 'Excited User <me@samples.mailgun.org>',
  to: 'john@example.com',
  subject: 'Hello',
  text: 'Testing some Mailgun awesomness!'
};

mailgun.messages().send(data, (error, body) => {
  console.log(body);  
});

This abstracts all the complexity behind the Mailgun API.
