Domain WHOIS Lookup
Look up domain registration information including registrar, creation date, expiration date, and nameservers. Useful for verifying domain ownership and checking domain age.
Check domain registration and ownership details
Why check WHOIS?
- Domain age affects email deliverability (older = better)
- Verify domain ownership and legitimacy
- Check when domain expires (renewal reminders)
- Identify the DNS/hosting provider
About this tool
Domain age matters for email deliverability—new domains are often viewed with suspicion by ISPs. Check your domain's registration details to understand its history and reputation. Ensure your domain has proper SPF, DKIM, and DMARC records configured, and verify they've propagated globally with our DNS propagation checker. You can also verify you're not on any email blacklists that might damage deliverability for your new domain.
