Email bounces destroy sender reputation, waste marketing spend, and kill campaigns. THE8.AI's 99.9% validation accuracy changes the game entirely.
The Hidden Cost of Bad Email Data
Every bounce hurts more than you think:
- 20% of email databases decay annually
- Hard bounces damage sender reputation for months
- $1 spent on bad data costs $10 in lost opportunities
- ESP penalties can blacklist your entire domain
