What can make Clay's numbers look wrong?

1. Your count of found emails can include some that may not work, because, as Clay's docs explain, the waterfall can accept emails with an unclear check when that setting is off.

   In Clay's own words: When off, the waterfall may accept emails where validation was inconclusive. Work Email waterfall - Clay Docs, read 2026-11-12.

2. Duplicate rows can stay in a Clay table and raise your lead count, since Clay's docs say its automatic duplicate removal skips blank cells and very long ones.

   In Clay's own words: Blank cells and cells with more than 200 characters are excluded from this process. Table management settings - Clay Docs, read 2026-11-12.

3. Older details can stay in a Clay table after things change, because, as its docs explain, with Keep existing results on, cells that already hold data are not run again.

   In Clay's own words: Cells that already have existing data will not run automatically. Table management settings - Clay Docs, read 2026-11-12.

How do I check Clay's numbers myself?

1. Run Clay on a handful of rows first and look at what comes back before trusting the totals from a large table.

   In Clay's own words: Test on a small sample before running at scale to assess how well a given pattern performs for your dataset. Work Email waterfall - Clay Docs, read 2026-11-12.

2. Comparing the Data Credits used with the rows that came back filled gives a rough check on how many lookups really found something in Clay.

   In Clay's own words: You'll only be charged Data Credits when Clay successfully returns data. Do unsuccessful searches consume Data Credits? What about Actions? - FAQ, read 2026-11-12.

Questions owners ask about Clay

• Why does my Clay people search return fewer leads than expected?People whose profiles are private are left out, so a search can return fewer people than work at a company.
• Why did the number of leads in my Clay table drop?A table set to pass rows on to another destination can delete them from Clay once that transfer succeeds, so the row count can fall while the leads still exist elsewhere.
• Why did my Clay table stop adding new leads?A table can only hold so many rows, so a busy source can reach the limit and new leads stop arriving.
