DMARC Checker.
How does DMARC Checker work?
Enter a domain (e.g., example.com) and click Check. We look up the DMARC record published at _dmarc.{site} and present it in a readable format—so you can quickly verify your policy, alignment, and reporting configuration.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email protection standard that tells receiving mail servers what to do when a message fails authentication—and how to report those results back to you.
What does a DMARC record look like?
Most DMARC records include:
v=DMARC1(version)p=(policy: none/quarantine/reject)- Optional reporting (
rua=) and alignment tags (adkim=,aspf=)
When should you check DMARC?
- After setting up SPF and DKIM for your domain
- When rolling out DMARC policy changes (especially moving to
quarantineorreject) - If your brand is being spoofed/phished
- When you stop receiving DMARC reports or mailbox providers flag issues

How do I check if my domain has a DMARC record?
Run a check for your domain. If DMARC is configured, you’ll see a record published at
_dmarc.yourdomain.com.What do
p=none,p=quarantine, andp=rejectmean?They’re enforcement levels: none monitors only,
quarantinetreats failing mail as suspicious (often spam), andrejectblocks failing mail.Do I need SPF and DKIM before enabling DMARC?
Yes—DMARC relies on SPF and/or DKIM passing (and aligning) to authenticate legitimate mail. Without them, enforcement can impact delivery.
What is DMARC “alignment” (aspf/adkim) in plain English?
Alignment checks whether the domain used by SPF/DKIM “matches” the visible From domain. Stricter alignment reduces spoofing but can require cleaner sending setups.
Where do DMARC reports go, and what is
rua=?rua=is the address (or provider endpoint) that receives aggregate DMARC reports. It’s how you monitor who’s sending mail for your domain and what’s passing/failing.Why does my DMARC record show up but still not work?
Common causes are publishing DMARC on the wrong hostname (not
_dmarc), typos in tags, missing SPF/DKIM alignment, or using a reporting address that can’t accept reports.Can I use DMARC on subdomains too?
Yes. Subdomains can inherit DMARC behavior from the parent domain, and you can also publish a specific DMARC record on a subdomain when needed.
