Bulk parked domain detector: which domains on your list are parked or for sale?
In short: Paste a list of domains and see which look parked or for sale, with the exact signal: parking nameservers, a marketplace redirect, parking assets or for-sale wording, as a CSV. Limit: Signals from nameservers, redirects and page text, not certainties.
A bulk parked domain detector checks each domain for the signs of a parking page. Paste up to 100 domains, or 500 after a free Google sign-in; each row says Looks parked, Looks for sale or No parking signal, naming the parking nameservers, marketplace redirect or page wording it saw. These are signals, not certainties. Download the CSV.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

Cleaning a list of company domains before outreach?
- Paste the domains here: 100 a run, or 500 after a free Google sign-in. Filter to the parked and for-sale rows and download the CSV.

How do I find parked domains in a list?
- Paste up to 100 domains, or 500 after a free Google sign-in, one per line; emails and URLs work too. You can also upload a CSV.
- Press Detect parked domains. Each domain's nameservers are looked up and its home page requested once, five at a time.
- Read each row: Looks for sale, Looks parked or No parking signal, with the signal that matched.
- Filter to the flagged rows and download the CSV.
Example
- You enter
- Three domains:
acme.example(Sedo parking nameservers),globex.example(redirects to a marketplace listing) andinitech.example(a normal site). - You get
- acme.example: Looks parked, its nameservers are Sedo's. globex.example: Looks for sale, redirects to a marketplace. initech.example: No parking signal. Download the CSV.
- Limits
- Up to 100 a run without an account and 500 when signed in with Google, counted over a minute. 10 sites a request; one GET of the home page from our server, no cookies, nothing stored.
What counts as a parking signal?
Four things: the domain's nameservers belong to a parking service such as Sedo or Bodis, the site redirects to a domain marketplace such as Dan or Afternic, the page loads files from a parking service, or the page says the domain is for sale or parked. Each row names the one it found.
None is proof. A company can park a domain it isn't using, and a parked domain can come with a site later.
Why does it matter for a lead list?
A company whose domain is parked or for sale has usually stopped trading under that name, and the addresses at it bounce. Flagging them before a send protects your sender reputation.
For a plain live-or-down read of every site, use the bulk website status checker. For who hosts a site, use the website host checker.
What do you do with the flagged rows?
Take them off the send list, or look at the company by name: it may have moved to a new domain.
Before you email anyone on the rest, verify the addresses.

Common questions
- How do I tell if a domain is parked?
- Paste it into a bulk parked domain detector like this one. It looks at the nameservers, any marketplace redirect and the page wording.
- Is this parked domain detector free?
- Yes. 100 domains a run without an account, 500 after a free Google sign-in, with no card, and a CSV download.
- What is the difference between parked and for sale?
- Parked means the domain shows a parking page; for sale means a marketplace redirect or wording offers it. The row says which signal it saw.
- Can a parked domain still have email?
- Sometimes. The tool reports parking signals only; use the MX lookup to see mail records.
- Does it check who owns the domain?
- No. It reads DNS and the home page, not WHOIS.
- Why does a parked domain show No parking signal?
- Its page may use wording or services we don't recognise. Open the site if it matters.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
