Calculation assumptions
- Estimated model — not a live ad-platform or email report.
- Clicks are treated as landing-page visitors; page-load loss is not modeled.
- Email delivery is assumed at 100%. Open rate is diagnostic only and never drives revenue.
- Buyers exit the sequence — no double counting across immediate and email stages.
- Profit shown is before non-ad costs (COGS, fees, refunds, taxes, fulfillment).
- Max break-even CPC equals revenue per click under this fixed-cohort model — the highest CPC at which forecast revenue still covers ad spend, before non-ad costs.
