Email Open Rate & CTOR Calculator
Email Open Rate & CTOR Calculator: Computes Open Rate = 200 / 1000 = 20.0% and CTOR = Clicks / Opens = 50 / 200 = 25.0%.
About this email open rate & ctor calculator
Computes Open Rate = 200 / 1000 = 20.0% and CTOR = Clicks / Opens = 50 / 200 = 25.0% Enables rapid evaluation of advertising efficiency and campaign economics without transmitting proprietary media budget figures.
Metrics formula & attribution logic
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Calculation and parameter relationship: openRatePercent=100×opens/delivered; ctorPercent=100×clicks/opens
Worked campaign analytics example

Input parameters & edge case boundaries
Operational constraints and validation boundaries: Parameter domains and units: delivered,opens,clicks ∈ ℤ; delivered,opens,clicks ≥ 0; delivered = 0 ⇒ openRatePercent = null; opens = 0 ⇒ ctorPercent = null. The tool uses the supplied aggregate counts as-is and does not require opens ≤ delivered or clicks ≤ opens; different provider measurement rules can yield rates above 100%. Results use binary64 floating-point numbers unless BigInt is stated. Result cards show up to 10 significant digits; raw output retains the serialized value. A null ratio means the model has no meaningful finite value for that ratio; it is not zero.
Marketing metrics in Email Open Rate & CTOR Calculator implement standard industry formulas (IAB/MRC). External ad platform reporting may differ slightly due to time zone cutoffs or attribution windows.
Local metrics evaluation boundary
Formula calculations and numeric evaluations in Email Open Rate & CTOR Calculator run synchronously in the browser JavaScript engine with zero server telemetry.
