How to Find Email Addresses at Companies Whose Website Moved

To find companies on an email list whose website moved, open each address's domain and see where the site ends up after redirects. The bulk email website redirect checker does this for every address in a pasted list or CSV and gives each one a row: Moves to another domain, Stays on its own domain or Website unreachable.

The check reads the domain's website, not the mailbox.

Why a moved website matters

A company whose old domain now sends visitors to a new one has often rebranded or been acquired. The address on your list may have moved to the new domain, or may have been closed with the old one. A moved site says nothing certain about its mail, so these rows are worth a look rather than a delete. 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. Open http://acme.example, https://acme.example, http://www.acme.example and https://www.acme.example.
3. Note the address each one ends on after its redirects.
4. If most end on a different registered name, the site has moved. Repeat for every unique domain.

For checking the redirect set-up of one site, see check www and non-www redirects.

Step 1: paste the addresses

Paste addresses one per line, or upload a CSV. Only the unique domains are sent, never the mailbox names, 5 a request.

Step 2: run the check

Press Check where sites redirect. Each home page is requested four ways from our server and redirects are followed, up to five hops. No mail is sent.

Step 3: read the result

Result	What it means
Moves to another domain	Most versions end on a different registered name; the end address is in the row
Stays on its own domain	The site ends on the same registered name, with or without www
Website unreachable	None of the four versions answered

The CSV carries the end address, the redirect set-up and any notes beside each address. No address is dropped from the list handed on to the mailbox check, because a moved site does not say whether mail works.

What this check cannot do

• It checks the domain, not the mailbox.
• A site that sends visitors by JavaScript or a link on the page is not followed.
• Four requests per domain, with no cookies.
• Up to 100 unique domains a run without an account, 500 signed in.

For bare domains use the WWW and HTTPS redirect checker. To weigh moved sites against parking signals and MX records, use find email addresses at companies that look gone.

Next: the rest of the list

For the addresses that remain, use the verify page: the first 100 checks are free with a Google sign-in, no card.
