Free Domain Age Checker
Check how old any domain is. See registration date, expiry date, and registrar info. Domain age matters for email deliverability.
How it works
Enter a domain name
Any domain. We look up the WHOIS registration data.
We query the WHOIS database
Registration date, updated date, expiry date, and registrar extracted.
See the domain age and details
Exact age in years and days, plus registration history.
Why this matters
Domain age is a trust signal for email providers. New domains (under 30 days) are far more likely to be flagged as spam. Most cold email experts recommend aging domains for at least 2-4 weeks before sending. Checking a domain age before buying or sending from it prevents wasted effort.

Got questions? We've got answers.
Email providers use domain age as a trust signal. Brand new domains have no sending history, so providers treat them with suspicion. Domains older than 30 days with clean history get better deliverability.
