Study type: Internal dataset profile Dataset: email_leads Published: September 13, 2026 Dataset measured: 2026-09-16 12:01:57

Key Dataset Measurements

26,512,569 Total database records
26,497,297 Estimated distinct stored email hashes
15,272 Estimated duplicate hash records
130 Distinct non-empty country labels

Email-Hash Duplicate Measurement

Among records containing a stored email_hash, the analysis found 26,512,569 records with a hash and 26,497,297 distinct hash values.

The difference is 15,272 records, equivalent to 0.06% of records containing a stored hash.

Interpretation:

This is a duplicate measurement based on the stored email_hash field. It is not an email deliverability measurement and does not determine whether an address belongs to a currently reachable person.

Field Completeness

Field completeness measures whether a field contains a non-empty stored value. It does not independently verify that the stored value is correct.
