Engagement Value Benchmarks
High-performing email programmes generate £0.10–£0.50 per subscriber per campaign in engagement value. Value per click typically ranges from £1–£5 depending on conversion rates and AOV.

How Engagement Value is Calculated
Engagement Rate = (Open Rate ÷ 100) × (Click Rate ÷ 100) × (Conversion Rate ÷ 100)
Value per Subscriber = Engagement Rate × Average Order Value × 100
Value per Open = Average Order Value × (Click Rate ÷ 100) × (Conversion Rate ÷ 100)
Value per Click = Average Order Value × (Conversion Rate ÷ 100)
Total Engagement Value = Value per Subscriber × List Size
This model translates engagement metrics into monetary terms, helping you understand the true revenue contribution of each subscriber action.
Understanding Email Engagement Value: From Metrics to Revenue
Most email marketers track engagement metrics — open rates, click-through rates, conversion rates — but rarely translate those numbers into monetary terms. Engagement value bridges this gap, showing exactly how much revenue each subscriber generates through their interaction with your emails. This shift from vanity metrics to value metrics transforms how you prioritise campaigns, allocate budget, and justify email investment to stakeholders who care about revenue, not percentages.
Calculating engagement value requires chaining together four metrics: open rate (what percentage of subscribers see your message), click-through rate (what percentage of opens result in clicks), conversion rate (what percentage of clicks result in purchases), and average order value (the typical revenue per transaction). Multiply these together to get the engagement rate, then multiply by average order value to arrive at the monetary value each subscriber generates per campaign. This number — typically £0.10–£0.50 for strong programmes — is the true measure of list quality and campaign effectiveness.
Why Engagement Value Beats Open Rates
Open rates tell you who saw your email, but engagement value tells you who made you money. A list with a 30% open rate but low click-through and conversion rates can have lower engagement value than a list with a 20% open rate but high downstream conversion. This is why segmentation matters — smaller, highly targeted segments often deliver higher engagement value than broad, generic blasts to the full list. Track engagement value by segment to identify your most profitable audiences and double down on campaigns that resonate with them.
Improving Engagement Value Over Time
The three levers on engagement value are click-through rate, conversion rate, and average order value. Click-through rate improves through better subject lines, personalisation, and compelling calls to action. Conversion rate lifts through landing page optimisation, stronger offers, and reducing friction in the purchase flow. Average order value increases through upsells, cross-sells, and product bundles. Test initiatives against each lever systematically and track engagement value monthly to measure improvement and justify continued investment in email optimisation.
Use this calculator to benchmark your current engagement value and model the revenue impact of improvements to open rates, click-through rates, or conversion rates. When you can show exactly how much each percentage point improvement is worth in revenue terms, optimisation becomes a strategic priority rather than a nice-to-have.
