How to Use the Retention Email Series Revenue Simulator
Multi-step automated email sequences tend to see engagement drop slightly with each additional send. This calculator applies your open rate, click rate, and purchase conversion rate to your subscriber count at each step, reducing reach effectiveness by 20% per subsequent step, and simulates total expected revenue across the whole series.
For example, with 10,000 subscribers, a 25% open rate, 15% click rate, 10% conversion rate, a $40 average order value, and a 3-step sequence, step one might produce around 37 conversions, step two around 30 based on the reduced reach, and step three around 24 — the calculator adds these up into cumulative revenue.
Actual open and click rates at each step may differ from these assumptions, so checking your email platform's campaign reports and adjusting the inputs will give you a more accurate forecast. It's also a useful way to spot which step is underperforming so you can improve content or timing there.
Frequently Asked Questions
When the same subscriber list gets repeated emails, people who already engaged tend to disengage further down the sequence, leaving mostly less-interested subscribers. This calculator reduces reach effectiveness by 20% at each subsequent step to reflect that.
The most accurate numbers come from your email platform's campaign reports (e.g. Klaviyo, Mailchimp) averaged over the last 3 months. If you don't have data yet, industry averages of 20-25% open rate and 3-5% click rate are a reasonable starting point.
