This is the Mailgun PHP SDK. This SDK contains methods for easily interacting with the Mailgun API. Below are examples to get you started. For additional examples, please see our official documentation at

To install the SDK, you will need to be using Composer in your project. If you aren't using Composer yet, it's really simple! Here's how to install composer:

curl -sS | php

The Mailgun api client is not hard coupled to Guzzle or any other library that sends HTTP messages. It uses an abstraction called HTTPlug. This will give you the flexibilty to choose what PSR-7 implementation and HTTP client to use.

If you just want to get started quickly you should run the following command:

php composer.phar require mailgun/mailgun-php php-http/curl-client guzzlehttp/psr7

Why requiring so many packages?

Mailgun has a dependency on the virtual package php-http/client-implementation which requires you to install an adapter, but we do not care which one. That is an implementation detail in your application. We also need a PSR-7 implementation and a message factory.

You do not have to use the php-http/curl-client if you do not want to. You may use the php-http/guzzle6-adapter. Read more about the virtual packages, why this is a good idea and about the flexibility it brings at the HTTPlug docs.


You should always use Composer's autoloader in your application to automatically load the your dependencies. All examples below assumes you've already included this in your file:

require 'vendor/autoload.php';
use Mailgun\Mailgun;

Here's how to send a message using the SDK:

# First, instantiate the SDK with your API credentials
$mg = Mailgun::create('key-example');

# Now, compose and send your message.
# $mg->messages()->send($domain, $params);
$mg->messages()->send('', [
  'from'    => '',
  'to'      => '',
  'subject' => 'The PHP SDK is awesome!',
  'text'    => 'It is so simple to send a message.'

Attention: $domain must match to the domain you have configured on

All usage examples

You find more detailed documentation at /doc and on


The result of an API call is, by default, a domain object. This will make it easy to understand the response without reading the documentation. One can just read the doc blocks on the response classes. This provides an excellent IDE integration.

$mg = Mailgun::create('key-example');
$dns = $mg->domains()->show('')->getInboundDNSRecords();

foreach ($dns as $record) {
  echo $record->getType();

If you'd rather work with an array than an object you can inject the ArrayHydrator to the Mailgun class.

use Mailgun\Hydrator\ArrayHydrator;

$configurator = new HttpClientConfigurator();

$mg = Mailgun::configure($configurator, new ArrayHydrator());
$data = $mg->domains()->show('');

foreach ($data['receiving_dns_records'] as $record) {
  echo isset($record['record_type']) ? $record['record_type'] : null;

You can also use the NoopHydrator to get a PSR7 Response returned from the API calls.

Warning: When using NoopHydrator there will be no exceptions on a non-200 response.


Debugging the PHP SDK can be really helpful when things aren't working quite right. To debug the SDK, here are some suggestions:

Set the endpoint to Mailgun's Postbin. A Postbin is a web service that allows you to post data, which is then displayed through a browser. This allows you to quickly determine what is actually being transmitted to Mailgun's API.

Step 1 - Create a new Postbin.
Go to The Postbin will generate a special URL. Save that URL.

Step 2 - Instantiate the Mailgun client using Postbin.

Tip: The bin id will be the URL part after It will be random generated letters and numbers. For example, the bin id in this URL,, is "aecf68de".

$configurator = new HttpClientConfigurator();
$mg = Mailgun::configure($configurator);

# Now, compose and send your message.
$mg->messages()->send('', [
  'from'    => '', 
  'to'      => '', 
  'subject' => 'The PHP SDK is awesome!', 
  'text'    => 'It is so simple to send a message.'

Additional Info

For usage examples on each API endpoint, head over to our official documentation pages.

This SDK includes a Message Builder, Batch Message and Opt-In Handler component.

Message Builder allows you to quickly create the array of parameters, required to send a message, by calling a methods for each parameter. Batch Message is an extension of Message Builder, and allows you to easily send a batch message job within a few seconds. The complexity of batch messaging is eliminated!

Framework integration

If you are using a framework you might consider these composer packages to make the framework integration easier.


We are currently building a new object oriented API client. Feel free to contribute in any way. As an example you may:

  • Trying out dev-master the code
  • Create issues if you find problems
  • Reply to other people's issues
  • Review PRs
  • Write PR. You find our current milestone here

Running the test code

If you want to run the tests you should run the following commands:

git clone
cd mailgun-php
composer update
composer test
