Step 2: Add Sending Domain to your mailgun account

After you have created your account mailgun account, now it's time to add a domain to your mailgun, which will contain the DNS records from the mailgun.

To add a domain:

  • Go to Sending > Domains
  • On the top right corner, click Add New Domain
  • Note From Mailgun When Adding a Domain
We recommend using a subdomain with Mailgun, like "". Using a subdomain you will be able to send emails from your root domain e.g. "[email protected]". If using a subdomain please make sure that you configure MX records for the subdomain for optimal delivery.
  • Enter your domain Name & Choose the domain region
  • Hit Add Domain

Step 3: Verify the Domain

After you click Add Domain, you’ll be taken to a screen asking you to add DNS records to your domain. Leave this screen open for the next step.

Once you get the DNS records generated by mailgun, you have to add these records to your hosting provider. For this tutorial, we are using Cloudflare to demonstrate the process.

Login to Cloudflare & click on DNS

Next, you’ll be asked what type of DNS records you want to add. We’ll go through each one individually.

TXT Records

The first records Mailgun asks you to add are TXT records. We will add two separate TXT records, one for SPF and one for DKIM. These are required to send and receive emails with Mailgun.


If you’re using a subdomain, add a new TXT record with as the hostname (with certain providers, you may just have to enter the subdomain, which would just be mail in this case) and the appropriate value Mailgun provides. You can leave TTL as the default option.


If you’re not using a subdomain, most providers will accept @ as the hostname when creating DNS records for the root domain. Here’s an example:


Clicking Add Record will add your first DNS entry for your domain!


Add another TXT record for Cloudflare only shows the subdomain, so your result will look like this:


MX Records

Next, you need to add MX records. Mailgun requires you to add two separate MX records.


You will add the MX records the same way you did with the TXT records. The hostname, in this case, is You’ll also be asked for priority, which should be 10.


CNAME Record

Lastly, you will need to add a CNAME record. The CNAME Record is what enables Open and Click tracking. This is highly recommended to reap the full benefit of Mailgun and gain insights into your email performance.


Add the CNAME the same way as the others. The hostname here is


Wait for a couple of minutes (Maximum an hour) to propagate.  & then click on Verify DNS button. If all records were propagated your domain will be verified if not then wait for some more time & retry (Make sure you have added the dns records correctly)

Step 4: Get the API key

For security, it's a good practice to generate a domain-specific API key instead of using your account API key.

Account API Key

you can grab your Account API Key by visiting Setting > API Keys

Sending domain API Key

For a domain-specific API key you need to generate one by Visiting Sending > Domain Setting > From the top right corner, Click Add Sending Key.

Add a short description to it & click Create Sending key

Note: The Generated key will be visible only once, So save it in a secure place.

Step 5: Add the key to your ghost publication

To Add the Sending API Key to your Ghost publication.

  • Login to your ghost admin
  • Navigate to Setting > Email newsletter
  • Under Email, Section Expand Email newsletter settings
  • Set the mailgun region
  • Add the domain name as you have added on mailgun
  • add the sending API key
  • Hit Save Settings on the top right corner

All done! now you can send bulk/newsletter emails to your subscribers.
