⚠️ The Hidden Cost of Cheap Data
Before you pick the cheapest option, consider this: Bad data costs more than good data.
Send 1,000 emails with 20% bounce rate = 200 bounces. Each bounce hurts your domain reputation. Deliverability drops from 90% to 70%. Suddenly your "cheap" data is costing you deals.
Test with a pilot before going all-in.
