Bulk email to company website finder: turn work email addresses into website links
In short: Paste email addresses and get each company's domain and a website link, with free, disposable and mail-less domains marked instead of linked. Limit: Reads the domain, never the mailbox, and doesn't say the person still works there.
A bulk email to company website finder turns each work email address into the company's domain and a website link, and marks free mailbox providers, disposable domains and domains that take no mail instead of linking them. Paste up to 1,000 domains a run, or 5,000 signed in. The link is built from the domain; the site isn't opened. It checks the domain, not the mailbox.
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

How does it turn an email address into a website?
The part after the @ is the company's domain for most work addresses. Mail hosts such as mail. or smtp. are reduced to the company's own registrable domain, and the website link is that domain over https. Free mailbox providers and disposable domains are marked, not linked, because they say nothing about where a person works.
To go the other way, from a company name to a domain, use the company name to domain tool.
Why isn't the website checked?
The finder never opens the site. A link built from a domain can point to a domain with no website, one that redirects, or one used for mail only. It is a starting point for research, not a verified URL.
For a plain list of the domains without links, use the email to domain extractor.
What does a company domain tell me about the mailbox?
Only that the domain takes mail. It doesn't say the person still works there. People leave companies, and their address is often closed within weeks. The mailbox check asks the mail server about each address, and the hand-off below carries the same list there.

What can’t this tool tell you?
- Reads the domain, never the mailbox, and doesn't say the person still works there.
- The link is built from the domain; the website is never opened or checked.
- The registrable domain is found by a common-ending rule, so unusual endings may keep an extra label.
- Up to 1,000 unique domains a run without an account, 5,000 signed in.
Common questions
- How do I find the website for an email address?
- Paste the address into a bulk email to company website finder like this one. It reads the domain after the @, skips free providers and gives a link for company domains.
- Is this bulk email to company website finder free?
- Yes. It is a free tool: up to 1,000 unique domains a run with no account, and up to 5,000 a run when you sign in with Google, with no card.
- Does it check that the website works?
- No. The link is built from the domain and the site is never opened, so it can point to a domain with no website.
- Why are Gmail and Outlook.com addresses not linked?
- They are free mailbox providers. Their domain says nothing about the person's company.
- Does it tell me whether the mailbox exists?
- No. It checks the domain, not the mailbox.
- Does it send an email to test?
- No. It reads the disposable list and DNS only.

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
