Why GHL Emails Show "via mailgun.org"

What "via mailgun.org" Means

When your GoHighLevel emails show "via mailgun.org" in the recipient's inbox, it means the DKIM signature on the email doesn't align with your sending domain. Email clients like Gmail display this warning when the authenticated domain (Mailgun's domain) doesn't match the domain in the "From" header (your domain).

Why This Happens

GoHighLevel uses Mailgun as its email sending infrastructure through the LeadConnector integration. When you set up a sending subdomain (e.g., mg.yourdomain.com), Mailgun needs DKIM records on that subdomain to sign emails with your domain's identity. Without these records — or with incorrectly configured records — Mailgun falls back to signing with its own domain, which triggers the "via mailgun.org" display.

The most common causes are:

• Missing DKIM CNAME records on the sending subdomain
• DKIM records placed on the wrong hostname (e.g., on the root domain instead of the sending subdomain)
• DNS provider formatting errors that cause the record to resolve to the wrong target
• Domain not verified in Mailgun — the records exist but Mailgun hasn't confirmed them yet

How to Fix It

Removing the "via mailgun.org" warning requires two things:

1. Correct DKIM CNAME records on your sending subdomain that point to Mailgun's DKIM keys
2. Verified domain status in Mailgun, which confirms the records are propagated and correct

Once both conditions are met, Mailgun signs outgoing emails with your domain's DKIM key, and the "via mailgun.org" warning disappears.

What FixMySender Does

FixMySender scans your sending subdomain, identifies whether the DKIM records are missing, misconfigured, or placed on the wrong hostname, and generates the correct CNAME records formatted for your specific DNS provider. After verification, FixMySender provides proof that the domain is verified and the "via mailgun.org" warning is resolved.
