Common Sales Intelligence Mistakes
Mistake 1: Not Verifying Emails
Problem: Trust database emails blindly.
Result: 15-20% bounce rate kills deliverability.
Solution: Always verify emails before sending (use ZeroBounce, NeverBounce).
Mistake 2: Buying More Data Than You Need
Problem: Buy ZoomInfo for $15K when you only target 500 accounts.
Result: Wasted money. Apollo at $588/year would work fine.
Solution: Match tool to your TAM size and budget.
Mistake 3: Ignoring Data Freshness
Problem: Export 10,000 contacts, email them 6 months later.
Result: 30%+ bounce rate. People change jobs.
Solution: Re-verify data every 90 days. Use real-time tools.
