My domain age check process before buying cold email domains

I have bought 200+ cold email domains over the years. Half the time, the random-name domain I buy has no history at all (fine). Sometimes it has GOOD history (a business that moved, the domain lapsed). Occasionally it has terrible history (spam operation used it, now blacklisted forever). Here is the checklist I run before buying any cold email domain.

Step 1: WHOIS history check. Use DomainTools or WhoisHistory.com. Look at the history of the domain. Domains that have been registered and expired multiple times are risk factors. Domains with clean history (never registered, or registered once and expired) are safe.

Step 2: Wayback Machine snapshot. Go to archive.org and search the domain. If the Wayback Machine has snapshots of the domain, read them. Most innocuous domains have 0 snapshots or snapshots of parked pages. If the domain was a legitimate business that shut down, that is actually good — it means some positive sender reputation exists.

Step 3: Blacklist check. MXToolbox blacklist lookup. Check the domain and any potential IPs associated with it. Domains on any major blacklist (Spamhaus, SURBL, URIBL) are dead on arrival for cold email. Skip them regardless of price.

Step 4: Google Safe Browsing and VirusTotal. Google the domain. Check if it triggers any security warnings. Run it through VirusTotal. A history of hosting malware or phishing content is disqualifying even if the previous bad actor is gone.

Step 5: Age signals. Fresh domains (under 30 days old) have zero age signals and will warm up slower. Domains 1-5 years old with clean history warm up faster. For cold email, 6 months to 2 years of age is the sweet spot. Anything older is a bonus.

Step 6: TLD considerations. .com is the cleanest TLD. .co, .io, .ai are acceptable. Avoid .online, .site, .xyz, .top — these are cheap TLDs heavily associated with spam and often fail anti-spam heuristics before anyone reads the email.

Where I buy. Namecheap for generic domains. Porkbun for cost efficiency. Spaceship for bulk buying. GoDaddy only when I cannot find elsewhere. Avoid domain marketplaces for cold email — aftermarket domains often have hidden history not visible in public records.

The budget. Generic .com lookalike domains: $8-15/year. Aged domains with clean history: $50-200. For a cold email operation with 10 domains, my annual domain budget is $150-300. Tiny compared to the infrastructure cost, and saves me from buying domains that will never deliver.

Spending 15 minutes on domain history saves months of deliverability pain. Do not skip this step.
