Why List Cleaning Matters for Your Marketing ROI
Your marketing database is decaying at 25% annually. Every invalid phone number costs you money, damages deliverability, and hurts campaign performance. Professional list cleaning isn't optional—it's essential for maximizing marketing ROI and maintaining sender reputation.
The Hidden Cost of Dirty Lists
Invalid phone numbers silently drain your marketing budget and destroy campaign performance. Most companies don't realize they're wasting 30-40% of their SMS spend on non-existent contacts.
- • SMS costs: $0.02-0.08 per message
- • 25% of numbers invalid annually
- • 40% are landlines (SMS incompatible)
- • Average waste: $2,000 per 100K numbers

Critical Insight: Data Decay Acceleration
Phone number data decay has accelerated to 30% annually due to increased number porting, remote work migration, and carrier changes. Lists older than 6 months typically contain 40% invalid numbers, making quarterly cleaning essential for maintaining data quality.
