Email & Domain Diagnostics
Eight focused checkers, each powered by live DNS lookups and AI explanations.
SPF Checker
Look up your SPF TXT record and let AI flag syntax errors, the 10-lookup limit, soft-fail vs hard-fail policy, and missing senders.
DKIM Checker
Fetch the DKIM TXT record at <selector>._domainkey.<domain> and check key type, length, and test-mode flags.
DMARC Checker
Look up _dmarc.<domain> and assess policy strength (none/quarantine/reject), pct, reporting addresses, and alignment.
MX Record Lookup
List a domain's MX records with provider detection (Google, Microsoft, Proofpoint…) and redundancy analysis.
IP Reputation
Run an IP through 100+ blacklists, ASN/geo lookup, and proxy/VPN/Tor detection. AI summarizes risk.
BIMI Checker
Look up default._bimi.<domain> and check the SVG logo URL, VMC certificate, and DMARC prerequisite.
Blacklist Checker
Scan a domain or IP against major real-time blocklists (DNSBLs, URI BLs). AI summarizes findings.
Domain Reputation
Combine blacklists, category (phishing/malware), domain age, and DNS posture (SPF/DMARC/MX) into one trust score.
