If you are using Ghost Pro Mailgun is configured by default and works out of the box but if you use the Self Hosted version of Ghost for example on DigitalOcean you can use Mailgun.

Mailgun is an email automation service that offers the possibility to send, receive and track emails effortlessly.

Mailgun Config

  1. Create a Mailgun account and log in.
  2. Under the Domains section click Add New Domain. (Hint: copy the password, you will need it later)
  3. Enter the domain from where you want to send the emails.
  4. Update your DNS records to verify that you are an authorized for the domain.
  5. Verify your domain in Mailgun (when DNS changes propagate).

Ghost config

Next step is to update the production configuration of the Ghost instance on the server. Open the config.production.json file in your Ghost root directory.

In this file there is a section responsible for mails.

"mail": {
  "transport": "SMTP",
  "options": {
    "service": "Mailgun",
    "host": "",
    "port": "587",
    "secure": true,
    "auth": {
      "user": "",
      "pass": "your_password"
  • service - defines which mail service we use, in this case Mailgun
  • host and port these two properties can be found going to Domain Settings then SMTP credentials
  • host - depends on the region, in our case
  • port - Mailgun servers usually listen on several ports (ex. 25, 587, and 465)
  • secure - if want to force a secure SMTP connection

After adding all the settings and saving the config file, restart Ghost:

ghost restart

Test Config

To test the configuration login in to the Ghost Admin Interface
Go to Labs and at the bottom of the page under Test email configuration click Send.

You can check your email, you should have received the test email.

Mailgun & Ghost Members

If you are using the Members feature, in order to send emails to people who subscribed to your publication, you have to do some additional setup within Ghost Admin:

  1. Go to Labs and Members section
  2. Click Expand in the Email Settings.
  3. Fill the From Address, members will receive emails from this address
  4. Fill Mailgun region and Mailgun domain, from your Mailgun account.
  5. Fill Mailgun API Key

To get the Mailgun API Key, in your Mailgun Dashboard go to Settings then API Keys and copy the Private API Key.

To test this as well, open any post and go to the Post Settings then click Email newsletter. You can set an email where you want to send the test email. Then click Send test email.

That's it, you should have a complete Mailgun Configuration for your self hosted Ghost CMS.
