How we calculate this

ESP waste: your bounce rate × volume × ESP CPM = money spent sending emails that bounced.
Deliverability recovery: industry benchmarks show each 1% bounce rate reduction improves inbox placement by ~8–12%, recovering a proportional share of email revenue.
After verification: average bounce rate drops to <0.5% (from 3–8% industry average).
