DievioLead List Quality Audit
Audit your own CSV for missing contact fields, duplicate emails and malformed addresses. See which rows need attention before importing or preparing outreach.
How to use this tool
- Paste or load a contact CSV.
- Map source columns to standard contact fields.
- Review coverage and fix the flagged source rows.
A worked example
Input
3 rows · company filled in 2 · same email appears twice
Output
company coverage: 66.67% Duplicate email flagged at its source row
The report separates populated-field coverage from individual issues. It does not turn a completeness score into a deliverability claim.
What the result means
Only mapped columns are audited. Coverage tells you what your file contains; an unmapped column is reported as not mapped rather than counted as a missing value in every record.
This audit measures the contents of your file. It does not check current employment, email delivery or whether a person fits your target market.
Frequently asked questions
Why does a field say “not mapped”?
No source column was assigned to that field. The tool cannot measure its coverage, so it omits that field from row-level missing-value checks. Map it if the source file contains the information. Reported CSV row numbers include blank records; a quoted multiline cell stays within one record.
Can this audit validate a person’s current job or email?
No. It checks the file’s structure, populated values, supported email format and duplicates. Current employment, buyer fit and deliverability require separate checks.
Is this free, and are my inputs uploaded?
