Bulk dead company website checker: which companies on your list look gone?
In short: Paste a list of company domains and get one verdict per row, combining what the home page returned, parking and for-sale signals and whether the domain has MX records, as a CSV. Limit: A combined signal, not proof a company closed.
A bulk dead company website checker combines three signals into one verdict per domain: what the home page returned, whether it looks parked or for sale, and whether the domain has MX records.

Cleaning a company list before outreach?
- Paste the domains here: 100 a run, or 500 after a free Google sign-in. Filter to the Likely gone and Check rows and download the CSV.
- Upload or paste it at /verify. Every address gets a live mailbox check, and the first 100 email checks are free with a Google sign-in, no card.
How do I find companies that have shut down in a list?
- Paste up to 100 company domains, or 500 after a free Google sign-in, one per line; emails and URLs work too. You can also upload a CSV.
- Press Check which companies look gone. Each domain gets DNS lookups and one request to its home page, five at a time.
- Read each row: Likely gone, Check (with what's missing), Moved, Site is up with no mail records or Looks alive, and the evidence behind it.
- Filter to everything except Looks alive and download the CSV.
Example
- You enter
- Three domains:
acme.example(does not resolve),globex.example(home page answers 503, no MX) andinitech.example(answers 200, has MX). - You get
- acme.example: Likely gone, the domain doesn't resolve. globex.example: Likely gone, site error and no mail. initech.example: Looks alive. 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.
How is the verdict built?
Likely gone means the domain doesn't resolve, looks parked or for sale, or has a site error or no site and no MX records. Check means something is wrong but mail is still set up, or the site refuses automated checks. Moved means the home page redirects to another site. Looks alive means the site answered and the domain has MX records.
A verdict is a signal. A company can be alive with a broken website, and a closed company's domain can keep answering for years.
Why combine site and mail?
A dead site with live MX records is a different case from a dead site with no mail: the first company may still read email. Putting both in one row saves you cross-checking two tools. For the site alone, use the bulk website status checker; for who hosts it, the website host checker.
Parking signals come from the same checks as the bulk parked domain detector.
What do you do with the flagged rows?
Remove Likely gone rows from the send list, look up Moved companies by name and keep Check rows for a manual look.
Before you email the rest, verify the addresses. A live site doesn't mean a given mailbox exists.

Common questions
- How can I tell if a company is still in business from its website?
- A site that doesn't resolve, is parked or has errors is a sign it may be gone. This tool combines those signals with MX records into one verdict.
- Is this checker free?
- Yes. 100 domains a run without an account, 500 after a free Google sign-in, with no card, and a CSV download.
- Does Likely gone mean the company closed?
- No. It means the signals point that way. A company can drop a domain and trade elsewhere.
- What does Moved mean?
- The home page redirects to a different site, often after a rebrand or acquisition. Search the company by name.
- Why does a live site show Check?
- It may refuse automated requests, or have no MX records, so contacts there can't receive mail.
- Does it check the contacts' email addresses?
- No. Verify them separately at /verify.
Sources
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.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
