What does your DMARC record actually say?
Paste a domain to see every tag in its DMARC record explained in plain English, plus the recommended next record to publish.
Frequently asked
- What does each tag mean?
- A DMARC record is a semicolon-separated list of tag=value pairs. Each row in the breakdown above names the tag as published and explains what it controls — policy, reporting addresses, alignment mode, and so on.
- What is rua= / pct= / adkim=?
- rua= is where aggregate (summary) reports are sent. pct= is the percentage of failing mail the policy applies to (100 when absent). adkim= (and its SPF counterpart aspf=) sets alignment strictness between the visible From: domain and the authenticating domain.
- Why is a tag flagged duplicate?
- Mailbox providers read only the FIRST occurrence of a given tag name in a DMARC record — a second rua= or a second p= is silently ignored, not merged. A duplicate badge means whatever is in that second tag is not doing anything.
