Check a file before you spend a credit
Drop a CSV with names and companies or LinkedIn URLs. We detect the columns, estimate the fill rate per field, and quote the credit range. Free. Nothing is charged until you run the job.

Up to 100,000 rows. Read in your browser; nothing leaves your machine in this check.
Every bulk enrichment vendor shows a calculator that assumes every row hits. This check reads your actual file in the browser, works out which columns we can match on, and estimates the fill per field from our averages. The live version goes one step further: it runs the first 500 rows and shows the first 25 results masked, so you see real coverage on your own list before paying.
What the check does
- 01
Reads the file in your browser
Nothing is uploaded in the free check. We look at the header row and count the rows.
- 02
Finds the match columns
LinkedIn URL, name plus company or domain, or email. Rename a column if we miss it.
- 03
Estimates fill and credits
Expected rows filled per field and the maximum credits, so the job's cost has a ceiling before it starts.
What the estimate is based on
| Match column | Work email | Personal email | Mobile |
|---|---|---|---|
| LinkedIn URL | 80% | 44% | 54% |
| Name + company or domain | 78% | 38% | 50% |
| Work email (reverse lookup) | 90% |

Coverage check questions
Is my file uploaded?
Not for this check; it runs in your browser. The live check after signup posts the first 500 rows to estimate from real matches, then deletes them.
How big a file?
Up to 100,000 rows for both the check and the job.
How accurate is the estimate?
It's our average fill for the match column you have. Your list will differ by country and role; the live 500-row check is the real number.
What columns do I need?
A LinkedIn URL column, or a name column plus a company or domain column. Everything else passes through untouched.
