Audit any email address with real DNS lookups for MX, SPF, DKIM & DMARC, DNSBL blacklist checks, RDAP domain age, and disposable email detection — all in one scan.
Our scanner performs live DNS queries, DNSBL lookups, and RDAP domain age checks — no simulation, no guesswork.
Strict RFC 5322 server-side validation to verify email address syntax is structurally correct and deliverable.
Real-time getmxrr() DNS query to verify mail exchange records exist and are properly prioritised.
Fetches domain TXT records and parses SPF policy — detecting strict (-all), soft-fail (~all), or permissive (+all) configurations.
Probes 30+ common DKIM selectors (google, default, selector1, mailjet, sendgrid, etc.) to detect active signing keys.
Queries _dmarc. subdomain for policy enforcement level — none, quarantine, or reject — and reports strictness.
Server-side check against 100+ known temporary/throwaway email providers including Mailinator, Guerrilla Mail, and YOPmail.
Live RDAP (Registration Data Access Protocol) query to determine domain registration date and calculate age in years/months.
Reverse-IP lookup against Spamhaus ZEN, SpamCop, SORBS, and Barracuda to detect if the domain's mail server is blacklisted.
Four steps to a complete, real-data email security report. No registration. No download. Completely free.
Type or paste any email address. Real-time client-side validation checks format instantly as you type.
Our PHP backend performs live DNS queries, RDAP lookups, and DNSBL checks, simultaneously.

Email security is no longer optional — it is the frontline of your digital identity. With billions of credentials exposed through data breaches every year, knowing whether your email address has been compromised is a critical first step in protecting your online presence. Email Privacy Checker builds on that foundation by combining live DNS authentication checks with real breach database lookups.
A secure email address depends on more than a strong password. The underlying domain must be properly configured with SPF, DKIM, and DMARC authentication records to prevent spoofing and phishing. Without these protocols, attackers can impersonate your domain, trick recipients, and bypass spam filters. Our tool performs real-time DNS queries for all three standards, detecting strictness levels and policy misconfigurations that leave your domain vulnerable.
Best practices for email privacy include using unique passwords per account, enabling two-factor authentication (2FA), monitoring breach exposure regularly with tools like ours, avoiding disposable emails for important accounts, and ensuring your domain's mail authentication records are fully configured. Whether you are a developer verifying domain health, a security professional auditing infrastructure, or an individual protecting personal data — our real-data checker gives you the intelligence to stay secure.
dns_get_record() and getmxrr() calls for MX, SPF, DKIM (30+ selectors), and DMARC; RDAP domain age via rdap.org; DNSBL reverse-IP lookups against Spamhaus, SpamCop, SORBS, and Barracuda; and a server-side disposable domain list check against 100+ providers.From XSS scanning to SSL testing — our security tool suite helps you find and fix vulnerabilities before attackers do.
