Bulk email dead company website checker: which addresses are at companies that look gone?
In short: Paste email addresses and get one verdict per address from the home page, parking signals and MX records: Likely gone, Check, Moved or Looks alive. Limit: Reads the domain, never the mailbox: a company that looks alive can still have a closed mailbox.
A bulk email dead company website checker reads the domain after the @ in each address and combines three signals: what its home page returned, whether it looks parked or for sale, and whether it has MX records. Paste up to 100 unique domains a run, or 500 signed in; rows read Likely gone, Check, Moved or Looks alive. It checks the domain, not the mailbox. 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

Got a lead list that may be full of closed companies?
- Paste it above to find the addresses at companies that look gone, with a CSV of every row.
- 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 email addresses at companies that have shut down?
- Paste email addresses, one per line, or upload a CSV. Addresses are found anywhere in the text, so a whole export works.
- Press Check which companies look gone. Only the unique domains are sent, never the mailbox names, 10 a request: DNS for mail records and one request for each home page. No mail is sent.
- Read each row: Likely gone, Check, Moved, Site is up with no mail records, or Looks alive, with the website and mail result.
- Filter to Likely gone, download the CSV, and hand the rest to the mailbox check.
Example
- You enter
- Four addresses:
jane@acme.example(site and mail up),tom@globex.example(parked domain),ana@initech.example(no website, no mail records) andbo@umbrella.example(redirects to another site). - You get
- jane: Looks alive. tom: Likely gone: domain parked. ana: Likely gone: no website, no mail. bo: Moved: redirects to another site. Download the CSV.
- Limits
- Up to 100 unique domains a run without an account and 500 when signed in with Google. 10 domains a request; DNS plus one request to each home page.
What does each verdict mean?
Likely gone means signals agree: a parked or for-sale domain, a domain that doesn't resolve, or no website and no mail records. Check means one signal is missing, for example no website but MX records still exist. Moved means the site redirects to another site. Site is up, no mail records means a live website with nowhere to deliver mail. Looks alive means the site answered and the domain has MX records.
The verdict is the same one the bulk dead company website checker gives for bare domains, attached here to each address.
Why combine the website and the mail records?
Either signal alone misleads. A broken website doesn't make a company dead, and a domain that still answers can belong to a business that closed. Mail records matter most for an email list: with no MX record, RFC 5321 falls back to the address record, and with neither the address will bounce.
The CSV shows the website status and the mail result in their own columns so you can set your own rule.
What do you do with Likely gone?
Take those addresses off the send list, or look at a few companies by name: a company that moved may have a new domain. Rows marked Check are worth a second look rather than a delete.
Before you email anyone on the rest, verify the addresses.

What can’t this tool tell you?
- Reads the domain, never the mailbox: a company that looks alive can still have a closed mailbox.
- A verdict is a signal from the home page, parking signals and MX records, not a certainty.
- Only the home page is read, once per domain, from our server; a site that blocks automated requests shows as Check.
- Up to 100 unique domains a run without an account, 500 signed in.
Common questions
- How do I find email addresses at dead companies?
- Paste the list into a bulk email dead company website checker like this one. It reads each address's domain and combines the home page result, parking signals and MX records into one verdict.
- Is this bulk email dead company website checker free?
- Yes. It is a free tool: up to 100 unique domains a run with no account, and up to 500 a run when you sign in with Google, with no card.
- Does it tell me whether the mailbox exists?
- No. It checks the domain, not the mailbox. A company that looks alive can still have closed a person's mailbox.
- Is Likely gone a certainty?
- No. It is a signal. A company can be alive with a broken site, or gone with a domain that still answers.
- Why does a site that blocks bots show as Check?
- When a site answers 401, 403 or 429 to an automated request, the tool says it refuses automated checks rather than calling the company gone.
- Does it send an email to the domain?
- No. It reads DNS and requests each home page once. It never connects to a mail server.

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
