Lead-generation evaluation checklist

1. Define the outcome: a target-account list, contact enrichment, qualification, CRM update, or outreach-ready segment.
2. Verify data rights: check provider terms, source permissions, privacy obligations, and regional requirements.
3. Test representative records: measure coverage, accuracy, freshness, duplicate handling, and missing-data behavior.
4. Set human checkpoints: require review before writing to a CRM, sending messages, or making qualification decisions.
5. Measure economics: record time saved, data costs, conversion quality, and the effort required to maintain the workflow.
