Domain Reputation Check
Check a domain’s reputation with trust and risk signals: age, DNS, hosting, and threat data.

DMARC Checker
Check if your domain has a valid DMARC record and see policy, pct, rua, ruf, and common errors.
SPF Checker
Test your SPF record: lookup chain, include depth, and avoid “too many DNS lookups.” Understand softfail vs fail.

Verify your DKIM TXT record. Enter domain and selector, check key length and alignment, and fix common misconfigs.

See how DMARC, SPF, and DKIM work together. Check all three and learn which to fix first.
