How this tool works

This calculator moves from sent emails to delivered emails, opens, clicks, conversions, and revenue, then compares revenue with campaign cost and optionally adjusts profit for gross margin.

Formula or template logic

delivered = emailsSent * deliveryRate; opens = delivered * openRate; clicks = delivered * clickThroughRate; clickToOpenRate = clicks / opens; conversions = clicks * conversionRate; revenue = conversions * revenuePerConversion; revenueROI = (revenue - campaignCost) / campaignCost * 100; marginAdjustedProfit = revenue * grossMargin - campaignCost

Example use case

If 10,000 emails have a 98% delivery rate, 3% CTR, 4% click conversion rate, and 120 revenue per conversion, the calculator forecasts conversions, revenue, ROI, and break-even volume.

Frequently asked questions

What is email marketing ROI?

Email marketing ROI compares the value generated by an email campaign with the cost of running it.

What costs should I include?

Include costs tied to the campaign, such as email software, creative production, design, copy, list rental, or promotion.

What is click-to-open rate?

Click-to-open rate divides clicks by opens. It helps compare click activity with the audience recorded as opening the email.

Why can open-rate estimates be imperfect?

Privacy features and image blocking can affect open tracking. Use clicks, conversions, and revenue alongside open rate.

Is this actual attribution?

No. It is a forecast or reporting calculation based on your inputs. Use consistent campaign dates and attribution rules.

Does this connect to an email platform?

No. It runs in your browser and uses only the numbers you enter.
