How to Find Email Addresses at Parked Domains in a List

To find email addresses at parked domains, check each address's domain for parking nameservers, a marketplace redirect, parking files and for-sale wording. The bulk email parked domain checker runs those checks for every address in a pasted list or CSV and gives each one a row: Looks parked, Looks for sale or No parking signal.

These are signals, not certainties, and the check reads the domain, not the mailbox.

Where parked addresses come from

Old signups, purchased lists and long-running CRMs collect addresses at companies that have since closed, merged or let a domain lapse. When the domain lapses it is often picked up by a parking service or listed for sale, and the addresses that were at it tend to go nowhere. A list of thousands of addresses has far fewer unique domains, so checking by domain is cheap.

The by-hand way

1. Take the domain after the @, for example acme.example from sam@acme.example.
2. Look up its nameservers with the bulk DNS lookup or any NS lookup, and see whether they belong to a parking service.
3. Open the home page. Look for a for-sale notice, a parking page or a redirect to a domain marketplace.
4. Repeat for every unique domain.

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 Find parked domains. Each domain's nameservers are looked up and its home page is requested once, from our server. No mail is sent.

Step 3: read the result

Result	What it means
Looks parked	A parking signal was found, named in the row
Looks for sale	A marketplace redirect or for-sale wording was found
No parking signal	None of the four signals was seen
Not checked or No answer	The page could not be read; the row says why

The CSV carries the signal text and the final URL beside each address. Flagged 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 parking service the tool does not list shows no signal.
• Only the home page is read, once per domain.
• Up to 100 unique domains a run without an account, 500 signed in. Free providers such as gmail.com are looked up like any domain.

The same signals for bare domains are in the bulk parked domain detector, and how to find parked domains in a list of company websites covers that case.

Next: the rest of the list
