Frequently Asked Questions
What is included in your Data Cleansing Services?
Data Cleansing Services cover deduplication, normalization, syntax/domain/MX email validation, disposable-inbox screening, phone verification, address hygiene, and suppression scrubbing — each file returns with a before-and-after audit report showing exactly what changed.
How much of a typical B2B database fails validation?
Most untouched B2B files show 5–15% duplicates and 3–10% invalid emails, plus decayed roles and departed contacts. We quantify every issue in the audit report so you can prioritize fixes.
Do you delete bad data or fix it?
Both, at your option: hard-invalid records can be suppressed or removed, while fixable issues — typos, formatting, outdated companies — are corrected against verified sources.
What is the turnaround time?
Most projects complete within 48 hours of receiving your file, with human researchers reviewing every edge case our automated gates flag rather than discarding good data blindly.
