Question 1

Why does domain age matter for cold email?

Accepted Answer

Email providers track domain reputation over time. Brand new domains have no sending history, so providers treat them with suspicion. Sending cold emails from a freshly registered domain almost guarantees landing in spam. Industry best practice is to wait at least 2 weeks (ideally 4+) and warm up the domain before sending outbound campaigns.

Question 2

How old should my domain be before sending cold email?

Accepted Answer

At minimum, 2 weeks old. For best results, wait 4-6 weeks while actively warming up the domain with genuine-looking email exchanges. Many experts recommend buying domains months in advance and letting them age while setting up DNS records.

Question 3

What is RDAP?

Accepted Answer

RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides structured, machine-readable data about domain registrations. This tool uses RDAP to look up the registration date and registrar information for your domain.

Question 4

Why can't I see the creation date for some domains?

Accepted Answer

Not all TLDs (top-level domains) support RDAP queries, and some registrars redact creation date information for privacy. Country-code TLDs (.uk, .de, etc.) may have limited RDAP support. In these cases, try a traditional WHOIS lookup for more details.

Question 5

Should I buy aged domains for cold email?

Accepted Answer

Buying pre-aged domains can help, but be cautious. Check the domain's history (Wayback Machine, blocklist checks) to ensure it wasn't previously used for spam. A clean 6-month-old domain is better than a 5-year-old domain with spam history.
