bulk-contact-enrichment

Use this when bulk enrichment must improve a file without turning it into an unauditable replacement. It produces an enriched export plus the counts and provenance needed to trust it.

Establish the job

Ask where the file came from and what happens after enrichment: outreach, CRM import, event follow-up, recruiting, or research. Confirm the requested fields and whether the run should fill blanks only or also flag conflicting values for review.

Do not assume that a column named email is a work email, that company is the current employer, or that a full-name field is safely splittable. The downstream use determines which ambiguities matter.

Profile before spending

Read the file without altering it. Report:

• row and column counts;
• encoding, delimiter, and header issues;
• duplicate rate;
• empty-row count;
• coverage of usable identity keys;
• current coverage of every requested output field;
• suspicious values, such as malformed profile URLs or personal-email domains in a work-email column.
