Warnings
- No check has been run yet.
DMARC policy check
Detect missing records, p=none monitoring mode, malformed tags, pct values, and alignment settings.
SPF syntax check
Review SPF mechanisms such as include, ip4, ip6, a, mx, redirect, and all.
Resolver-backed results
Results come from Convertr server resolvers and should be treated as practical diagnostics, not a global DNS propagation report.
Frequently Asked Questions
Does this send a test email?
No. This tool only checks public DNS TXT records for DMARC and SPF.
Does this check DKIM?
Not yet. DKIM checks require a selector, so this focused checker starts with DMARC and SPF.
Why are reporting addresses redacted?
DMARC rua and ruf values can expose private reporting mailboxes. The checker shows whether those tags exist without exposing the full addresses in JSON output.
