After your successful registration with Mailgun service, the first step is to go to the Domains tab. For the fresh new account, you will see one record saying sandbox domain, which allows testing the development phase emails of your application before going to production.

Now, our concern is to setup emails environment for the production application.

In this article, we are going to look more in-depth about Domain Verification & DNS.

Before you add a few DNS configuration to the hosting partner end, the Mailgun shows the status of your domain as Unverified.

Note: I am taking Digital Ocean as my hosting partner, but not only Digital Ocean, this article works for any hosting provider which gives you access to manage DNS settings from their user panel based on what type of plan you choose from them.

After completing the above few things in the Mailgun end, we now have to log in into the hosting partner, for me its Digital Ocean.

Digital Ocean

After logging into digital Ocean dashboard, navigate to the Networking tab. It shows you the list of domains attached with droplets you own for your applications.

If you are going to manage the new domain, add it to the list, or select the existing one from the list.

Digital Ocean DNS PanelWe have to add a few DNS records like TXT, MX, CNAME to verify the Mailgun domain form the Digital Ocean DNS management panel.

Add following records under the Networking >

  • A record should always point to your droplet's IP Address, not the IP Address given by previous Mailgun configuration page.
  • While adding TXT record given by Mailgun, wrap them in double quotes before saving in Digital Ocean end.
  • TXT, MX, CNAME should be the correct value from Mailgun.

Mailgin Domain VerificationAfter all setup, you have to lastly go to Mailgun, under Domain Verification & DNS click on Check DNS Record Now, to verify the domain configuration page.


If you are using Mailgun with Laravel, you have to update your .env file or config/mail.php to use mailgun driver, and config/services.php

'mailgun' => [
    'domain' => 'your-mailgun-domain',
    'secret' => 'your-mailgun-api-key',

To get the API Key, select the domain from the Domains list, and you will see it on that page.


To test your production emails, now perform some email sending functionality, the emails log will appear in the Mailgun dashboard as processed, delivered, dropped and so on.
