How Do I Add a Domain?

Domains are obviously fundamental to begin using your Mailgun account; it's where you're sending from! Aside from the limited testing options provided by an account's sandbox domain, a custom or personal domain is required to send emails through our platform, build a reputation, and establish a professional identity with your emails.

Check out our article on how to choose a domain if you do not already have a domain. 

To configure a domain in our system, if you're using the classic UI (options across the top, with a silver background), use the following instructions:

  • Click the Domains tab within your Mailgun Control Panel.
  • On the following page, click Add New Domain.
  • Enter your Domain Name and click Add Domain.

If you're using the beta UI (options displayed down the left-hand side on a dark column) the API keys are only available under the Settings page. To locate the API keys use these instructions:

  • Click on Messages on the left-hand side of your the Mailgun dashboard.
  • Click the green Add New Domain button.
  • Enter your Domain Name and choose your additional options.
    • The region your domain will reside: US or EU.
    • Create DKIM Authority - you would generally leave this checked by default.
    • DKIM Length - a longer DKIM key will make spoofing your emails by malicious spammer more difficult. 1024-bit is selected by default, but 2048-bit can be used as well.
      Note: Some DNS providers may have an issue with a 2048-bit DKIM keys, as they produce a string longer than 255 characters (exceeding the maximum character limit for a DNS entry). 
  • Once your options are set, click Add Domain to save your new domain.

The next page will provide you with the DNS records required for your domain to be verified with Mailgun. This information is also available in the Domains section of the control panel by clicking on a specific domain name

If you need assistance getting your domain verified, check out this help center article

If you would like to add a domain using the domains API, you can find more information in our documentation.
