Bad Data Is Costing You More Than You Think
Every invalid email erodes your sender reputation, wastes budget, and puts your entire email program at risk.
Average email list decay rate per year
Email addresses go stale fast. Without verification, a quarter of your list is dead weight costing you money.
Bounce rate that triggers ISP penalties
Cross this line and your domain reputation tanks. ISPs throttle or block your sends entirely.
Cost per invalid email sent through your ESP
You're paying your email provider for every bad address. On a 100K list, that's thousands wasted monthly.
Of emails never reach the inbox
Spam traps, role accounts, and disposable addresses destroy deliverability. Most senders don't know until it's too late.
