DIAG-04 / DIAGNOSTICS
Domain Age Checker
Find when a domain was first registered, when it was last updated, and when it expires — useful for assessing trust and reputation.
About the Domain Age
A domain's age is a useful trust signal: freshly registered domains are disproportionately associated with spam and abuse, while long-established domains carry more reputation. This tool pulls a domain's registration, update, and expiry dates from WHOIS.
What this tool checks
It performs a WHOIS lookup and extracts the creation date, last-updated date, and expiry date, then calculates the domain's age.
Why age matters
Mail and security systems weigh domain age when assessing trust. A domain under 90 days old often faces extra scrutiny, so newly registered domains should warm up sending gradually.
Frequently asked questions
Why does domain age matter for email?
Spam filters treat brand-new domains with suspicion because abusers register domains in bulk. Older domains with consistent history are trusted more, improving deliverability.
Where does the age come from?
From the domain's WHOIS creation date. This tool queries WHOIS and calculates the elapsed time since registration.
Can I see a domain's expiry date?
Yes, when the registrar publishes it in WHOIS. This tool shows the expiry date alongside the creation and last-updated dates.
