FAQ
How accurate is enrichment data?
Best providers: 85-95% email accuracy. Phone: 70-80% accuracy. Verify emails before sending. Test with small batches first.
Is intent data worth it?
Yes, if you act on it. Intent data adds 20-30% lift when used for timing outreach. Useless if just sitting in CRM.
How do I choose between tools?
Match to your needs: Startups = Apollo/Lusha (affordable). Enterprise = ZoomInfo/6sense (comprehensive). Technical = Clearbit (API-first).
What about data compliance?
GDPR and CCPA apply. Use compliant providers. Honor opt-outs. Document lawful basis. International data has stricter rules.
Can I use multiple tools?
Yes. Many companies use ZoomInfo for comprehensiveness + Bombora for intent + Clearbit for real-time. Waterfall enrichment catches more.
