Simple modelEach send is modeled with the same subscriber count and funnel rates. Revenue is reduced by refunds, then gross margin is applied before campaign cost is deducted. This mode does not model unsubscribes or list growth between sends.

Advanced modelEach send starts with the current list, applies delivery, click and conversion rates, then removes modeled unsubscribes and adds new subscribers before the next send. Contribution from conversions is compared with setup, platform, creative/labor and sending costs.

Scope
Email ROI depends on attribution and list quality
This calculator estimates email economics from the assumptions entered. It does not prove that every conversion was caused by email, distinguish first-touch from last-touch attribution, model inbox placement by provider, account for spam complaints, suppressions or inactive-user policies, or estimate long-term brand effects. Open rate is intentionally not required because privacy protections and automated image loading can make opens less reliable for revenue modeling. Future contribution should be used only for value beyond the revenue already entered.
