About Email Armory

What We Do

Email Armory offers 17 free tools for DNS lookups, email verification, and domain security analysis. No signup required, no tracking of your queries, and no external API dependencies. Every tool runs on native Node.js APIs, which means zero third-party costs and maximum reliability.

Why We Built This

Most DNS and email security tools on the web haven't been updated in years. Competitors like MXToolbox still use interfaces that look like they were designed in 2008, are cluttered with intrusive ads, and provide a terrible experience on mobile devices. Email Armory is the modern alternative — clean UI, fast results, mobile-first design, and no paywall gatekeeping basic lookups.

Our Tools

Our tools are organized into three categories:

• Email Tools — Verify email addresses, check MX records, validate SPF, DKIM, and DMARC configurations, inspect SMTP banners, and test email headers.
• DNS Tools — Look up any DNS record type, check propagation, perform reverse DNS lookups, query WHOIS data, and analyze DNS health.
• Security Tools — Inspect SSL/TLS certificates, check domain blacklists, scan email server ports, and verify HTTP security headers.

Technology

Email Armory is built with Next.js, TypeScript, and Tailwind CSS. All lookups — DNS queries, TLS handshakes, SMTP connections, WHOIS requests — are performed using native Node.js APIs. There are no external API costs, no rate-limited third-party services, and no middlemen between you and your results.

Privacy

We don't store your queries or results. There are no user accounts, no tracking cookies, and no analytics on individual lookups. Your data stays between your browser and the DNS/SMTP servers we query on your behalf. Read our full Privacy Policy for details.
