Email Bounce Waste Calculator
Quantify how much of your email budget and revenue opportunity is leaking to bounces and invalid contacts. Provide monthly platform spend and your bounce rate, then optionally add send volume and revenue per delivered email to surface wasted spend, bounced messages, and revenue lost.
Informational only; validate bounce definitions and revenue attribution with your ESP and analytics stack before acting.

FAQ
What counts as a bounce for this estimate?
Use the combined hard bounce, invalid, and blocked percentage. Soft bounces that later deliver should be excluded from the rate you enter.
How should I estimate revenue per delivered email?
Divide your attributed revenue by delivered emails over a recent period, excluding bounce volume, to capture real monetization per delivery.
Can I use this for SMS or push?
Yes. Replace the spend and bounce rate with your channel equivalents and keep the revenue per delivered message aligned with that channel.
Additional Information
- Spend waste multiplies the ESP spend by your bounce rate, assuming fixed-cost sending plans priced per message or audience size.
- Revenue loss treats bounced emails as lost revenue opportunities at your stated revenue per delivered email.
- Default revenue per email is set to $0.05 to reflect typical ecommerce benchmarks if you leave it blank.
- Reducing bounce rate improves deliverability signals and can lower CPM pricing from some providers.
