Check any domain's security and get a free domain trust score (A–F) in seconds. We grade email authentication (SPF, DKIM, DMARC), TLS, DNSSEC, HTTP security headers, and DNS — scored by severity with actionable findings.
Frequently Asked Questions
What is a domain trust score?
A domain trust score is a single A–F grade summarising a domain's security across DNS, email authentication (SPF, DKIM, DMARC), TLS/HTTPS and web security. DomainScores shows exactly which checks passed or failed and why.
Is the domain and email security check free?
Yes. Enter any domain in the checker above for an instant, free report — no signup and no software to install.
Can DomainScores tell me if my domain can be spoofed?
Yes. We check SPF, DKIM and DMARC. If your DMARC policy is not at enforcement (p=quarantine or p=reject), attackers can send email that appears to come from your exact domain. The report flags this — see our email spoofing guide.
Why are my emails going to spam?
Common causes are missing or misconfigured SPF, DKIM or DMARC records, poor sender reputation, or being on a blacklist. The free check flags which apply to your domain — see why emails go to spam.
What does DomainScores check?
DNS configuration and DNSSEC, email authentication (SPF, DKIM, DMARC), TLS/HTTPS and certificate health, and web security headers — graded against a published methodology.
