How to Find Email Addresses at Companies That Look Gone

To find email addresses at companies that have closed, give each address's domain one verdict from three signals: what its home page returned, whether it looks parked or for sale, and whether it still has MX records. The bulk email dead company website checker does that for a pasted list and returns Likely gone, Check, Moved or Looks alive for every address.

It is a signal, not a certainty, and it checks the domain, not the mailbox.

Why one signal is not enough

A broken website does not make a company dead. A domain that still answers can belong to a business that closed. For an email list, the mail records matter most: with no MX record, RFC 5321 falls back to the domain's address record, and with neither the address will bounce. Putting the three signals together removes most of the false alarms.

The by-hand way

1. Open the domain's home page and note the status or what the page says.
2. Look for parking or for-sale wording and check the nameservers.
3. Look up the domain's MX records.
4. Decide a rule, for example: no site and no MX means gone.

For one lead, that is five minutes. For a list, see how to remove dead companies from a lead list, which does the same for bare domains.

Step 1: paste the addresses

Paste addresses one per line, or upload a CSV. Only the unique domains are sent, never the mailbox names, 10 a request.

Step 2: run the check

Press Check which companies look gone. DNS is read for the mail records and each home page is requested once from our server. No mail is sent.

Step 3: read the result

Result	What it means
Likely gone	Signals agree: parked or for sale, does not resolve, or no site and no mail
Check	One signal is missing, or the site refuses automated requests
Moved	The site redirects to another site
Site is up, no mail records	A live site with nowhere to deliver mail
Looks alive	The site answered and the domain has MX records

The CSV has separate website and mail columns, so you can apply your own rule. Likely gone addresses are left out of the list handed on to the mailbox check.

What this check cannot do

• It checks the domain, not the mailbox: a company that looks alive can have closed a person's address.
• A company can be alive with a broken site, or gone with a domain that still answers.
• Only the home page is read, once per domain.
• Up to 100 unique domains a run without an account, 500 signed in.

For a list that should also be sorted by parking signals alone, use the bulk email parked domain checker. For a wider lead-list quality check, combine it with a mailbox check.

Next: the rest of the list
