Bulk WHOIS & DNS Lookup – Domain Age, RDAP, Email Provider, Tech

Look up thousands of domains in one run and get WHOIS/RDAP registration, DNS, email setup and website status in one row per domain, for $3 per 1,000 domains. Paste domains, URLs or email addresses. You get the registrar, creation and expiry dates, domain age in days, availability, nameservers, MX/SPF/DMARC (and optional DKIM), the company's email provider (Google Workspace, Microsoft 365, Zoho…), tools that send email for it (HubSpot, Salesforce, SendGrid…), ~50 SaaS tools verified in DNS (Atlassian, Slack, Stripe, OpenAI, DocuSign…), DNS host, and whether the website is up.

• ✅ Official sources: IANA RDAP bootstrap, registry WHOIS servers (fallback) and DNS-over-HTTPS
• ✅ WHOIS + DNS + email + website in one row, so you don't need four separate tools
• ✅ Any input: domains, full URLs or emails, normalized to the registrable domain (co.uk, com.au…) and deduplicated
• ✅ No API key, login or proxy. Pay per domain, and it stops at your Maximum cost per run

Try it now: the input is pre-filled with 7 real domains, URLs and emails (stripe.com, openai.com, apify.com, an @hubspot.com address, bbc.co.uk, spiegel.de, producthunt.co). Click Start; the test run below took about 46 seconds with all checks on. Turn off the website check for faster bulk runs.

Real run results (18 Oct 2026)

Pre-filled input, all default checks (run zrd4c12eVJk6EgIIz, 7 domains, about 46 seconds). ceo@hubspot.com and https://www.apify.com were normalized to their domains. .de registries do not publish dates, so spiegel.de has DNS and email data but no WHOIS dates.

Pricing

Pay per event: $0.003 per domain ($3 per 1,000 domains) with WHOIS/RDAP, DNS, email intelligence and the website check all included. No start fee. Set a Maximum cost per run and the Actor stops cleanly when it's reached.

How that compares with other WHOIS/DNS Actors on the Apify Store (free-tier list prices from the Store API, checked 18 Oct 2026):

Actor	Price per 1,000 domains	Start fee	What's in a row
This Actor	$3.00	none	WHOIS/RDAP + DNS + SPF/DMARC/DKIM + email provider + SaaS + website
Domain WHOIS & DNS Lookup (santamaria-automations)	$3.00	$0.001	WHOIS + DNS + email provider
Whois Domain Lookup (agenscrape)	$2.50	none	WHOIS
Domain Availability Checker (automation-lab)	$2.30	$0.035	availability + WHOIS basics
Bulk Domain Availability Checker + WHOIS (bridgeworks)	free (platform usage only)	none	availability + RDAP
Domain Availability, Expiry, WHOIS, DNS (datascoutapi)	$0.99	$0.00005	WHOIS + DNS + IP/ASN

If you only need registrar and expiry dates, a WHOIS-only Actor can be cheaper. Choose this one when you also want email provider, DMARC, SaaS stack and website status for lead scoring or security checks.

Tips

• Disable includeWebsite for the fastest bulk WHOIS + DNS runs.
• Schedule a weekly run on your portfolio and filter daysUntilExpiry < 30 to catch renewals.
• Filter domainAgeDays < 90 to flag newly registered domains in fraud or lead-qualification flows.

FAQ

Is this legal? Yes. It queries public registration data through the official RDAP protocol and registry WHOIS services, public DNS, and each domain's public homepage. Some registries restrict reuse of WHOIS data (e.g. for marketing) — follow their terms and applicable privacy laws.

Why is the registrant often empty? Since GDPR most registrars redact registrant contact data. When it is public, you get organization and country.

A TLD isn't supported? A few registries (e.g. .es) offer no public RDAP/WHOIS; you'll still get DNS, email and website data and a whoisError note. Open an issue in the Issues tab for requests.

How do I find which companies use Google Workspace or Microsoft 365? Run your domain list and filter the emailProvider column. Combine it with emailSenders (HubSpot, Salesforce, Marketo…) and saasVerifications for tech-stack segments.

Can I check if a domain is available? Yes. registered: false means the registry has no record of it. Always confirm at a registrar before buying.

How fast is it? The 7-domain test above took about 46 seconds with every check on and concurrency 5; slow registries and slow websites take most of that time. For big lists, turn off the website check and raise Concurrency (up to 20).

Is RDAP the same as WHOIS? RDAP is the official, structured JSON successor to WHOIS run by the same registries. This Actor uses RDAP first and falls back to port-43 WHOIS where RDAP isn't available.
