Check SPF, DKIM, and DMARC records for any domain with plain-English explanations.
Checks SPF, DKIM, and DMARC DNS records via Cloudflare DNS-over-HTTPS.
Check a domain's email authentication DNS records — SPF, DKIM, and DMARC — in one place. Looks up the relevant TXT records via Cloudflare DNS-over-HTTPS, parses each one, and explains it in plain English. Flags common misconfigurations like missing SPF, multiple SPF records, +all (insecure), and DMARC p=none (monitoring only), then scores your overall email security and gives clear recommendations. DKIM common selectors are probed (default, google, selector1, selector2, k1, mail, dkim, s1, s2).
