Use this guide when Wix is hosting DNS for your domain and NTS has asked you to update DMARC for email security monitoring.

DMARC is published as a TXT record at the host name _dmarc. Your domain should have only one _dmarc TXT record.

If your domain is connected to Wix by pointing and DNS is hosted somewhere else, make this change at the DNS host instead of Wix.

Sign in to Wix with an account that can manage domains and DNS records.

Official Wix DNS reference: https://support.wix.com/en/article/connecting-an-email-purchased-outside-of-wix

Replace the current _dmarc TXT value with the following NTS DMARC record:

v=DMARC1; p=reject; rua=mailto:dmarc@networkthinking.ai; ruf=mailto:dmarc@networkthinking.ai;

Host name: _dmarc

Record type: TXT

Value: paste the full record exactly as shown above, including the trailing semicolon.

Policy: p=reject tells receiving mail systems to reject messages that fail DMARC alignment. Confirm with NTS before applying this policy if you are unsure whether all legitimate email senders are already authenticated.

DNS updates can take time to propagate. Wix and other DNS providers commonly advise allowing up to 48 hours for DNS changes to fully update.

After saving, send a screenshot of the _dmarc TXT record to support@networkthinking.com or ask NTS to verify the record publicly.

The final DNS result should show one TXT record for _dmarc.yourdomain.com with this exact value:

v=DMARC1; p=reject; rua=mailto:dmarc@networkthinking.ai; ruf=mailto:dmarc@networkthinking.ai;

If Wix does not show Manage DNS Records, confirm that Wix is actually hosting DNS for the domain.

If Wix reports a duplicate record, search the TXT section again for an existing _dmarc entry and edit it instead of adding a new one.

If you use a third-party email platform, marketing platform, CRM, or ticketing system to send mail as your domain, make sure SPF and DKIM are configured for those senders before enforcing p=reject.
