Email Infrastructure
Mailgun + HostGator Domain Setup
Step-by-step DNS configuration for connecting Mailgun to a domain hosted with HostGator's cPanel.
What You'll Learn
This guide walks through signing up for Mailgun, adding your domain, and configuring the five DNS records Mailgun requires — two TXT records, two MX records, and one CNAME — inside HostGator's cPanel Zone Editor.
It also covers how to avoid breaking your existing Google Workspace/Gmail mail delivery while adding Mailgun's records.

Step 3
If your domain is companyname.com, decide whether to set up the main domain or a subdomain with Mailgun.

Next Steps
Once all records are verified, grab your Mailgun API key and add it to your email service settings.
Then send a test email to confirm everything works — see how to send a test email in the Conversation.
9Frequently Asked Questions
Q: Where do I find the Zone Editor in cPanel?
Log in to cPanel, look for the Domains section, and click Zone Editor. From there, find your domain and click Manage to view and add DNS records.
Q: Should I use my main domain or a subdomain with Mailgun?
If you already use your main domain with Google Workspace or another email provider, use a subdomain (like mg.companyname.com) for Mailgun instead to avoid mail routing conflicts.
Q: What does "do not include the root domain" mean for the Name field?
In cPanel's Zone Editor, the Name field only needs the subdomain portion — the root domain is added automatically. So for mg.companyname.com, you'd enter just "mg", not the full domain.
Q: Will this break my existing Gmail or Google Workspace email?
Not if you use a subdomain for Mailgun rather than your main domain, and leave your existing MX records for Google Workspace untouched on the main domain.
Q: How long does it take for DNS records to verify?
DNS propagation is usually fast, but it can occasionally take a few hours. If a record isn't showing green yet, wait a bit and click Verify DNS Settings again.
Q: What do I do after all 5 records show a green checkmark?
Grab your Mailgun API key, add it to your email service settings, and send a test email in a conversation to confirm delivery is working.
