- Add TXT on
_dmarc, or CNAME on_dmarcto the Hosted DMARC target. - Save; Namecheap may take a few minutes to answer publicly.
Hosted DMARC on this provider
If you use Sender Identity Hosted DMARC, delete the TXT at _dmarc and publish only this CNAME. We publish the DMARC TXT on our side, starting at p=none with rua at reports.senderidentity.com.
| Type | Name / host | Value / points to | Note |
|---|---|---|---|
CNAME | _dmarc.brand.example | brand.example._dmarc.hosted.senderidentity.com | DNS only on Cloudflare. Remove any TXT at the same name. |
After the CNAME resolves, open Account on the site, confirm delegation shows ready, and keep reading aggregate reports before you approve quarantine or reject.
Check the result
- Wait for DNS TTL (often 5 minutes to an hour).
- Run the free static audit on the domain.
- Confirm the DMARC check shows the policy you expect, and that a CNAME path is not blocked by a leftover TXT.
