Fix Sparkforge Email Replies When Wix Manages Your Domain

By Sparkforge Support Team ·Last reviewed May 3, 2026

Wix-managed nameservers block Mailgun reply records. Switch nameservers to your registrar, replace the A and CNAME records, then add Mailgun DNS to restore Sparkforge email replies.

Sparkforge email replies fail on Wix-hosted domains because Wix nameservers do not allow the Mailgun DNS records Sparkforge needs. The fix is to move nameservers back to your registrar and recreate the records Wix was managing automatically.

Why This Breaks

When Wix manages your nameservers, you cannot add the MX, TXT, and CNAME records Mailgun requires for inbound replies. Switching to your registrar's nameservers gives you full DNS control, and you can recreate the A and CNAME records Wix needs to keep the website live.

Step 1: Change Nameservers Off Wix

  1. Log into your domain registrar (GoDaddy, Namecheap, etc.).
  2. Open the DNS or nameserver settings for the domain.
  3. Switch from Wix nameservers to your registrar's default nameservers.

Step 2: Recreate Wix DNS Records

Reference the Wix support article on DNS records needed to connect a domain to Wix and copy the values into your registrar's DNS panel.

  1. Add the A record Wix specifies, pointing to their IP.
  2. Add the CNAME record for www pointing to wwwXX.wixdns.net (the value Wix lists).

Step 3: Verify Propagation

Use dnschecker.org to confirm each record is live globally.

  • Check yourdomain.com for the A record.
  • Check www.yourdomain.com for the CNAME.
  • Check yourdomain.com for the NS record showing your registrar's nameservers.

Load your website to confirm it still resolves correctly.

Step 4: Add Mailgun DNS Records

With nameservers under your control, follow the Sparkforge Mailgun setup guide to add the MX, TXT (SPF, DKIM), and CNAME records Mailgun requires for inbound and outbound mail.

Frequently Asked Questions

Will my Wix site go down during the switch?

Briefly, yes. DNS changes take 5 minutes to a few hours to propagate. The site comes back as soon as the new A and CNAME records resolve.

Do I need to repeat this every time I add an email feature?

No. Once nameservers are off Wix, all future DNS changes happen at your registrar.

What if I do not have a separate registrar?

If Wix is also your registrar, transfer the domain to a registrar with full DNS support before adding Mailgun records.

Frequently Asked Questions

Why does Wix block Mailgun replies?
Wix nameservers do not expose the full DNS record set, so MX and TXT records Mailgun needs cannot be added. Switching to your registrar's nameservers restores full DNS control.
Will my Wix site go offline during the change?
There is usually a brief gap during DNS propagation, typically minutes to a few hours. Once the new A and CNAME records resolve, the site returns.
Do I have to keep using Wix?
No. Many Sparkforge users move their site to Sparkforge's built-in funnels and websites and consolidate everything in one platform.
How do I confirm DNS changes are live?
Use dnschecker.org and search for your A, CNAME, and NS records. All three should reflect the new values across most global servers.
