Four utilities, zero paywalls
Each tool answers one question well — is this email real, how old is this domain, what does its DNS say, and what was registered today.
Email Validator
Verify any email address instantly. Check syntax, DNS records, and SMTP mailbox existence to ensure deliverability before sending.
Domain Age Checker
Find out when a domain was registered, its age, expiry date, registrar, and nameservers. Essential for SEO and due diligence.
DNS Lookup
Query A, MX, NS, TXT, SPF, and DMARC records for any domain. Diagnose email deliverability and DNS configuration issues.
New Domain Finder
Browse newly registered domains across 72+ TLDs. Filter by date range and extension for lead generation, brand monitoring, and market research.
Not toys — production infrastructure with a free front door
These tools query live registries and authoritative DNS through the same Go services we run for our own systems.
- Email checks run three layers: RFC 5322 syntax, DNS/MX lookup, and mailbox verification
- Domain data comes from live RDAP/WHOIS registry queries — no stale caches
- DNS answers cover A, AAAA, MX, NS, TXT, CNAME, and SOA records
- New-domain feeds are built from daily zone monitoring across 72+ TLDs
- The same Go engines power our production lead-generation platform
