How This Calculator Works
Email Marketing turns the inputs into a visible formula-based estimate. Use it to turn campaign inputs into a decision-friendly view of spend, conversion, revenue, MER, CAC, and funnel quality.
Use the email marketing calculator to summarize email campaign performance from sent emails, opens, clicks, conversions, and revenue.
The calculator divides each campaign outcome by the relevant upstream count: sent emails, opens, or clicks.
Formula
Open rate = opens / sent. CTR = clicks / sent. CTOR = clicks / opens. Revenue per email = revenue / sent.
Example Calculation
50,000 sent, 18,000 opens, 2,400 clicks, and $12,600 revenue gives $0.25 revenue per email.
When to Use This Calculator
- Summarize email campaign performance
- Compare campaign quality
- Estimate revenue per email sent
Practical Scenarios
- Use the calculator before moving budget so spend, conversion rate, order value, and margin stay connected. Use case: Summarize email campaign performance.
- Model conservative, base, and optimistic campaign assumptions when traffic quality or conversion rate is uncertain. Start with Email Marketing, then compare the changed result with the original.
- Pair it with related marketing calculators when campaign results affect CAC, LTV, revenue, or profit. This is especially useful when you need to estimate revenue per email sent.
Tips
- Use delivered emails if available
- Compare CTOR to isolate message engagement
- Segment transactional and promotional campaigns
Common Mistakes
- Using opens as the denominator for CTR
- Ignoring deliverability
- Comparing campaigns with different audiences without context
- Optimizing for clicks, opens, or revenue without checking margin, fees, refunds, or customer quality.
- Comparing campaigns with different attribution windows, funnel stages, or order-value assumptions.
Assumptions and Limitations
The Email Marketing Calculator is most useful when spend, traffic, conversion, revenue, and margin assumptions describe the same campaign window. Review the formula, assumptions, and related calculators before using the result in a decision.
- Refunds, chargebacks, taxes, payment fees, labor, seasonality, and contracts can change real outcomes.
- The result is a planning estimate, not accounting, tax, legal, or professional advice.
- Verify assumptions against current records before changing prices, budgets, or strategy.
