Validating a full contact base, repairing orphaned records, and handing the system back documented

The problem

The play

1. 1
   Validate every email, then re-enrich the failures

   Ran the full contact base of roughly 16,000 records through an email-validation service, about 90 percent came back valid, and re-enriched the flagged addresses through a ten-provider enrichment waterfall, updating several hundred records rather than simply suppressing them.

2. 2
   Repair orphaned records

   Auto-associated roughly 1,000 companyless contacts to companies, creating about 800 new company records and matching the remainder to existing ones, and backfilled blank company names so account-level reporting had something to roll up to.

3. 3
   Two dedupe passes, one manual

   Worked a manual merge pass across roughly 1,500 records, then a same-name pass that merged roughly 150 of about 180 duplicate groups, the manual pass deliberately kept a human in the loop for the ambiguous merges.

4. 4
   Triage the pipeline before handing it over

   Surfaced roughly 150 overdue open deals with per-owner triage lists so owners could close them out or re-date them before exit, rather than leaving the incoming team a forecast full of stale opportunities.

5. 5
   Retire what nobody uses

   Ran a final hygiene audit retiring stale dashboards and workflows, so the inherited system carried no silent automation the internal team would later have to reverse-engineer.

6. 6
   Document the handoff properly

   Produced a full offboarding enablement guide with screen-recorded walkthroughs so the in-house team could operate everything independently once the engagement ended.
