What it does
Company Active Check looks at each company's website and tells you whether it is live. For every domain in your list it reads three things: whether the domain resolves in DNS, whether it has a mail server (an MX record), and whether the website answers an HTTP request. From those signals it works out a 0 to 100 active score and sorts each row into a band: active, uncertain, or inactive.
It is a reachability check on the website, not a company registry or a KYB check. A live site is a strong signal that a company is still operating, but the tool is built to clear out the obviously dead and defunct ones in bulk, so the list you import is worth your time. Run it before dedupe and before a CRM import. It is available on Pro, Team, and Agency.
How to use it
Upload your file
CSV or Excel. Operelio finds the website or domain column automatically. If there is more than one, you pick which to check.
Run the check
Click Run. Operelio checks each unique website once and reuses the result across every row that shares it. A run costs one job, with no per-row charges.
Read the results
You get a plain-language summary, stat cards for active, uncertain, inactive, and unique sites, and a scored preview. Every row carries a band, a 0 to 100 score, a reason, and the signal columns.
Keep the live ones
Drag the export slider to the active score you want and download just the rows at or above it. A toggle decides whether rows with no website come along. The full scored file stays untouched in your history.
Send it on
Pass the clean list straight into the Email Verifier or CRM Formatter, so you only verify and import companies whose sites are live.
Want a quick read on a single company? Use the instant check box at the top. Paste one domain and get its score, band, and signals on the spot, with no upload and no job spent.
The three bands
Every row lands in one of three bands, derived straight from its 0 to 100 active score so the two always agree. You can sort, filter, and cut the file on either one.
| Band | What it means | Typical signals |
|---|---|---|
| Active | The website looks live. | The domain resolves, often has a mail server, and the site answers cleanly with a 200. |
| Uncertain | Mixed signals. A human should glance at it. | The domain resolves but the site is slow to answer, returns an unusual status, or redirects away to another domain. |
| Inactive | The site is dead or unreachable. | The domain does not resolve, nothing answers, or the page is parked or for sale. |
Rows with no website to check are marked unknown and counted on their own, so a blank cell is never scored as dead. Sites that do have a website but answer with genuinely mixed signals are scored uncertain rather than guessed at; dead and unreachable sites are scored inactive. So every row with a website lands in active, uncertain, or inactive, and unknown is reserved for the rows that had nothing to check.
What gets added to your file
Your original file with new columns added at the right. The headline columns are the verdict; the rest are the signals it was built from, each its own column so you can filter on any of them.
| Column | What it holds |
|---|---|
| company_active | The band: active, uncertain, or inactive. |
| liveness_score | The 0 to 100 active score. The primary number to sort and cut on. |
| liveness_reason | A short plain-language note that names the signals behind the verdict, like "does not resolve" or "parked page". |
| domain_resolves | Whether the domain answers in DNS: yes, no, or unknown. |
| mail_server | Whether the domain has a mail server (an MX record): yes, no, or unknown. |
| http_status | The status the website returned, or a note like timeout or refused when it did not answer. |
| final_url | The address the site lands on after any redirects. Flags a company that moved to a new domain or forwards to a parking page. |
| built_on | The platform the site runs on (such as Shopify or WordPress) when it can be detected, otherwise blank. |
| tls_certificate | Whether the site has a valid certificate, an expired one, or none. |
| response_speed | How quickly the site answered: fast, slow, or timed out. |
| parked | Whether the page is a parking or for-sale holder rather than a real site. |
Keeping only the companies you want
The results page has one slider that controls a filtered download. Drag it to the active score you are comfortable with, and the download keeps only the rows at or above that line. A toggle decides whether rows that had no website to check are kept or dropped.
The slider never changes the scored file. It only controls which rows the filtered export contains, so you can re-cut at a different score whenever you like. The full scored file stays in your history within your plan's retention window.
Because the band comes from the score, cutting at a score is the same as keeping a band. Cut low to keep everything that is not clearly dead; cut high to keep only the strongest active sites.
When to use it
Run it early, on any list where dead companies are a real risk. Common scenarios:
| Scenario | What the check tells you |
|---|---|
| An aged list that has sat in a spreadsheet for a year | Which companies have since shut down or let their site lapse. |
| A scraped or bought list | How much of it is dead weight before you pay to dedupe, verify, or import it. |
| Before a CRM import | Which records are worth a seat and which would just inflate your pipeline numbers. |
| Before the Email Verifier | Which domains are gone, so you do not spend verify credits on companies that no longer exist. |
| A partner or reseller list | Which listed companies still have a live presence to point a customer at. |
Plans and limits
Company Active Check is on Pro, Team, and Agency. A run costs one job from your monthly allowance, with no per-row credits and no per-domain charges, because the DNS, mail, and reachability checks do not call a paid outside service.

What happens to your data
Your original upload is never changed. The scored file and any filtered export are stored as separate files linked to your account.
Files are deleted from storage after the retention window for your plan: 24 hours on Free, 30 days on Pro, 30 days on Team, 90 days on Agency. You can also delete files manually at any time.
The check reads public DNS and website signals for the domains in your file. It does not share your list or use it to train models.
Frequently asked questions
Does Company Active Check tell me a company is still in business?
No. It tells you whether the company's website is live, which is a strong signal that a company is still operating, but it is not a company registry or a KYB check. A live site can belong to a dormant business, and a healthy company can have a slow or recently moved website. Read the score as "is this website live and reachable", then use your own judgment on the borderline rows.
What plan do I need?
Company Active Check is on Pro, Team, and Agency. It is not on the Free plan. A run costs one job from your monthly allowance, and the instant single-domain box does not spend a job at all.
How is the active score worked out?
From three reachability signals: whether the domain resolves in DNS, whether it has a mail server, and whether the website answers an HTTP request, along with supporting signals like the final URL after redirects, the TLS certificate, response speed, and whether the page is parked. A site that resolves, has mail, and answers cleanly scores high; one that does not resolve or sits on a parking page scores low. The band (active, uncertain, inactive) is derived from the score.
What happens to rows with no website?
They are marked unknown and counted separately on the results page, never scored as dead. The export slider has a toggle so you can decide whether those rows are kept in or dropped from the filtered download.
Will it change my data?
No. The check reads each website and writes the band, score, reason, and signal columns into a new file. Your original upload is never modified, and the export slider only controls which rows the filtered download contains.
What do I do after the check?
Export the live companies with the slider, then send the clean list into the Email Verifier to check the addresses, or into CRM Formatter to map and push to HubSpot, Salesforce, or Pipedrive. Checking liveness first means you do not spend verify credits or a CRM seat on companies that are already gone.
