Enrichment Coverage

ZoomInfo’s coverage is industry-leading but varies:

Segment	Email Coverage	Phone Coverage
US Enterprise	80-90%	60-70%

US SMB	60-70%	40-50%

Phone number strength is ZoomInfo’s differentiator—direct dials are significantly better than competitors.

For gaps in coverage:

Use Clay waterfall enrichment
Add Cognism for Europe
Add Lusha for additional mobile numbers

ZoomInfo Analytics

Common Issues

Issue: Low Match Rates

Symptoms: Enrichment returns <60% matches

Solutions:

Ensure email domains are business (not personal)
Check data formatting (clean before uploading)
Try company domain matching for Account enrichment
Use waterfall enrichment for gaps

Issue: CRM Sync Duplicates

Symptoms: Duplicate records appearing in Salesforce/HubSpot

Solutions:

Configure ZoomInfo to match on email + ZoomInfo ID
Enable “update existing” instead of “create new”
Use CRM duplicate rules as safety net
Run periodic deduplication (DemandTools)

Issue: Credit Burn Rate Too High

Symptoms: Running out of credits before renewal

Solutions:

Review user export activity (identify heavy users)
Implement export approval workflows
Use saved searches instead of re-running queries
Bulk export vs individual exports (better credit rates)
Focus exports on high-value targets

Issue: Intent Data Not Actionable

Symptoms: Too many or too few intent signals

Solutions:

Refine topic selection (be more specific)
Adjust score thresholds (raise minimum)
Combine intent with other filters (size, industry)
Create workflows that auto-prioritize (don’t just alert)

Issue: Outdated Contact Data

Symptoms: Contacts have changed jobs, emails bounce

Solutions:

Enable automatic re-enrichment
Set up job change alerts
Regularly refresh key accounts
Cross-reference with Breeze Intelligence or other sources

Compliance and Data Privacy

If targeting European contacts:

ZoomInfo provides GDPR-compliant data
Honor opt-out requests promptly
Document legitimate interest basis
Use suppression lists

CCPA Considerations

For California contacts:

Respect do-not-sell requests
Provide data deletion upon request
Maintain consumer rights processes

Best Practices

Data Handling:
- Export only what you need
- Don't store ZoomInfo data outside approved systems
- Respect suppression lists
- Document consent where required
- Train users on compliance requirements
