DMARC test
Check any domain
in seconds.
Enter a domain — we read its DMARC record from public DNS and tell you instantly whether email authentication is set up cleanly. No sign-up, no tracking, runs entirely in your browser.
DNS query goes directly to Cloudflare. We don't see the lookup.
What is DMARC?
Protection in
one DNS entry.
DMARC is a TXT record in your domain's DNS that tells receiving servers: "Here's how to handle mail in this domain's name."
A typical record looks like:
v=DMARC1; p=reject; rua=mailto:dmarc@example.ch
Receivers like Google, Microsoft and Yahoo check every inbound mail against this record and send you daily aggregated reports. Without a record your domain is freely spoofable — anyone can write in your name. With a record and an active policy, spoofers are blocked.

Common questions
What we
get asked.
- Does my domain pass through Solvia servers during the test?
- No. The DNS query goes straight from your browser to Cloudflare (DoH). Solvia never sees the domain you test.
- What exactly is checked?
- We fetch the TXT record at _dmarc.<your-domain> and verify it's a valid DMARC1 record. We look at policy (p=), reporting (rua=) and subdomain inheritance (sp=).
- What's the difference between p=none, p=quarantine and p=reject?
- p=none is observe — reports flow, spoofs are still delivered. p=quarantine sends spoofs to spam. p=reject bounces them before delivery. Best practice: escalate in this order, don't skip steps.
- My result is PASS — am I done?
- PASS means: the setup is technically clean. That's half the win. The other half is ongoing report analysis — recognising sending sources, spotting anomalies, fine-tuning the policy. That's exactly what Deemarc is for.
- My result is FAIL — how fast can we fix?
- A first observational DMARC record can be in place within 15 minutes. The clean escalation to p=reject takes 30–60 days of reporting. We can walk you through it.
