Email & security tools, simplified.
Free tools to analyze email headers, verify domain health, detect phishing, and create temporary inboxes. No signup. No tracking. Just answers.
Header Analyzer
Paste email headers and get a plain-English breakdown with risk scoring. Trace the delivery path, check authentication, spot red flags.
Domain Health Check
Enter any domain to check SPF, DKIM, DMARC records, MX configuration, and blacklist status. Know if your emails will land.
Phishing Detector
Paste a suspicious email address or link. We'll check domain age, reputation, authentication records, and known threat databases.
Temporary Inbox
Generate a disposable email address with a countdown timer. Receive emails in real-time. When the timer expires, everything is gone.
DNS Lookup
Look up all DNS records for any domain — A, AAAA, MX, TXT, NS, CNAME, and SOA — in one fast query.
SPF, DKIM & DMARC Checker
Check a domain's email authentication records for spoofing protection. We look up SPF, DKIM, and DMARC and explain any misconfigurations in plain English.
Blacklist Checker
Check if a domain's mail server is listed on major email blacklists (DNSBLs). Find out why your mail lands in spam.
SSL Certificate Checker
Inspect any website's SSL/TLS certificate — issuer, validity dates, days until expiry, and every domain it covers.
Encoder / Decoder
Encode and decode Base64 and URL strings right in your browser. Handy for inspecting email links and encoded payloads.
Password Generator
Generate strong, cryptographically-secure passwords locally in your browser. Nothing is ever sent to a server.
Email Breach Checker
Check if an email address has been exposed in known data breaches, and see exactly which breaches it appeared in.
Password Breach Checker
Find out if a password has leaked in a data breach. Checked with k-anonymity — your password never leaves your browser.
