SPF, DKIM & DMARC record checker
Enter a domain to read its live email authentication records, with the faults that cause spam-foldering flagged automatically. Runs entirely in your browser against public DNS — we never see the domain you check.
Lookups run in your browser against Google’s public DNS resolver. We store nothing.
What this checks
SPF
That exactly one record exists, that it is syntactically valid, and whether it ends in ~all or the weaker +all.
DKIM
The common selectors used by Google Workspace, Microsoft 365, Zoho and cPanel, since DKIM selectors cannot be enumerated from DNS.
DMARC
That a policy exists, and whether it is actually enforcing (quarantine / reject) or just monitoring.
