How Revenue per Open is Calculated
Revenue per Open = Total Revenue ÷ Total Opens
Value per Subscriber = Total Revenue ÷ List Size
Opens per Subscriber = Total Opens ÷ List Size
Projected Monthly Revenue = List Size × (Open Rate ÷ 100) × Revenue per Open × Campaigns per Month
Revenue per open reveals the monetary value of each engagement event. Track this metric by campaign and segment to identify your highest-value audiences and content types.
Why Revenue per Open is the Ultimate Email Performance Metric
Revenue per open distills email performance into a single, actionable number: how much money each open generates. This metric cuts through vanity metrics like open rate and click rate to reveal actual business impact. A campaign with a 15% open rate generating £0.20 per open outperforms a 30% open rate campaign generating £0.05 per open by 33% in total revenue. Revenue per open tells you which campaigns, subjects, and content types drive the most value per engagement, making it the ultimate guide for optimisation decisions.
Calculating revenue per open requires two inputs: total revenue attributed to email campaigns and total opens across those campaigns. Divide revenue by opens to arrive at the per-open value. Track this metric campaign-by-campaign to identify patterns. Promotional campaigns typically deliver higher revenue per open (£0.15–£0.30+) while educational content delivers lower immediate revenue (£0.02–£0.08) but builds long-term engagement. Use revenue per open to balance campaign mix — promotional sends for immediate revenue, educational sends for long-term relationship building.
Improving Revenue per Open
The three levers on revenue per open are click-through rate (getting openers to visit your site), conversion rate (turning visitors into buyers), and average order value (increasing transaction size). Click-through rate improves through compelling CTAs, urgency-driven copy, and visual hierarchy that guides the eye to action buttons. Conversion rate lifts through landing page optimisation, offer strength, and checkout friction reduction. Average order value increases through upsells, cross-sells, and product bundles. Test initiatives against each lever and track revenue per open to measure impact.
Using Revenue per Open to Guide Campaign Strategy
Track revenue per open by segment, campaign type, and time period to identify your highest-value opportunities. If VIP customers generate £0.50 per open while general list generates £0.08, prioritise VIP campaigns and invest more in moving general list subscribers into VIP status. If product launch campaigns deliver £0.30 per open while weekly newsletters deliver £0.05, shift resources toward launches and reduce newsletter frequency. Revenue per open transforms email from a broadcast channel into a precision revenue engine where every decision is guided by per-engagement profitability.
Use this calculator monthly to benchmark revenue per open and set improvement targets. Even small gains compound — increasing revenue per open from £0.10 to £0.12 (a 20% improvement) generates 20% more revenue from the same open volume, making every optimisation test a direct investment in channel profitability.
