Estimate an email campaign's revenue and ROI from your list size, open and click rates, conversion, and average order value.
Multiplies list × open rate × click rate × conversion × order value. Rates here are of the preceding step (click rate is of opens). Real results vary with list quality, offer, and timing. Email consistently ranks among the highest-ROI channels, but garbage-in applies. General information only.
Email revenue is a funnel: of everyone you send to, a fraction open, of those a fraction click, of those a fraction buy — each multiplying down to orders, then revenue at your average order value. Because the cost is usually low, ROI is often high, which is why email remains a top-performing channel.
Revenue = sent × open% × click% × conversion% × order value
They vary widely. Open rates of 20–45% and click rates of 2–15% of opens are common ranges — use your own campaign history for accuracy.
Because sending to an owned list costs little, most of the revenue is profit. That's why building an email list is one of the best long-term marketing assets a small business can own.
