Mailgun + SiteGround Domain Setup
Step-by-step DNS configuration for connecting Mailgun to a domain hosted with SiteGround.
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 SiteGround's DNS Zone Editor.

It also covers how to avoid breaking your existing Google Workspace/Gmail mail delivery while adding Mailgun's records.

8Verify DNS & finish setup

Now that you've added all 5 records, go back to Mailgun and click Verify DNS Settings. If some records still aren't showing a green checkmark, click the same button again — DNS propagation can take a little time.

9Frequently Asked Questions

Q: Where do I find the DNS Zone Editor in SiteGround?
Log in to SiteGround, then go to Site Tools → Domain → DNS Zone Editor. From there you can add TXT, MX, and CNAME records for your domain.
Q: What if "Add your own MX records" isn't available?
This option appears under the MX tab in the DNS Zone Editor. If you don't see it, confirm you're on the correct domain and that email hosting isn't locked to a different provider in your SiteGround plan.
Q: Should I leave the Name field empty or use @ for the main domain?
Either works in SiteGround's DNS Zone Editor — both represent the root domain. Use whichever the field accepts without an error.
Q: Will this affect my existing Google Workspace or Gmail 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 DNS propagation take with SiteGround?
Usually fast, but it can occasionally take a few hours. If a record isn't showing green yet in Mailgun, 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.
