How to use Email Campaign Calculator
- Enter delivered emails, opens, clicks, conversions, revenue, and campaign cost from the same send or reporting window.
- Check open rate, click rate, click-to-open rate, conversion rate, revenue per email, and ROI together instead of judging a single metric.
- Use the funnel visual to see where the largest audience drop happens, then compare the exact scenario table before changing subject lines, offers, or landing pages.
Calculator guide
Understanding Email Campaign Calculator
Email performance is a sequence from delivery to open, click, conversion, and revenue. Viewing the complete funnel prevents one strong top-of-funnel rate from hiding weak downstream performance.
Calculation method
How the calculation works
Open rate = unique opens / delivered; click-to-open rate = unique clicks / unique opens. Calculate each funnel rate from its appropriate prior or delivered denominator. Subtract campaign cost from attributed revenue and divide by cost for a simple revenue-based ROI.

Frequently asked questions
Why can open rate be unreliable?
Image prefetching and privacy controls can create or hide recorded opens.
What is click-to-open rate?
It measures clicks among recipients who recorded an open.
Should bounces be included in delivered messages?
No. Delivered should exclude hard and soft bounces under your provider's definition.
Does the ROI result include gross margin?
No. This page reports a simple revenue return; use Marketing ROI for a margin-adjusted analysis.
