Enrichment & Data FAQ

Frequently asked questions about how ContactLevel enriches your contacts with advertising data.

What Does Enrichment Do?

ContactLevel automatically enriches each contact with up to 50–70 advertising-relevant data points including professional info, personal identifiers for ad matching, and firmographic data.

How Long Does Enrichment Take?

• Under 10,000 contacts: ~15 minutes

• Over 10,000: up to 1 hour

• 50,000+: several hours

Why Are Some Contacts Not Enriched?

• Insufficient data (no email, LinkedIn URL, or company domain)

• Outdated information (job/company changes)

• Limited public professional footprint

Does Enrichment Cost Extra Credits?

No. Enrichment is included with the contact import credit. Re-enrichment is also free. See Credit Usage & Billing.

What If Enrichment Data Looks Wrong?

• Check your source data first (wrong email/LinkedIn URL can match wrong person)

• Contact support if source data is correct but results are unexpected

How Does Enrichment Affect Match Rates?

More enriched data points = higher match rates on ad platforms. Import contacts with LinkedIn URLs and work emails for best results.

Does Enrichment Happen on Re-Sync?

• New contacts: enriched automatically

• Existing contacts: not re-processed (no extra credits)

• Re-sync only sends net-new data to ad platforms
