Why Data Decays
People change jobs (25-30% annually in tech). Companies merge or close (5-10% annually for SMBs). Phone numbers get reassigned. Email addresses get retired.
The Impact
2-year-old list: 50% accuracy at best. 1-year-old list: 70-80% accuracy. Real-time data: 95%+ accuracy.
How to Fix Stale Data
1. Use real-time tools (DatabaseLists, Apollo).
2. Re-verify before each campaign.
3. Email validation (NeverBounce, ZeroBounce).
4. Quarterly database refreshes.
