Why Normalise by 1,000 Subscribers
Raw revenue figures favour whoever has the biggest list. Revenue per 1,000 subscribers removes list size from the equation, so you can compare a 2,000-subscriber list against a 200,000-subscriber list on equal terms — and benchmark your own performance month over month.
Most email programs generate between £50 and £300 per 1,000 subscribers per month, with high-performing ecommerce and B2B lists exceeding £500. The metric is also the basis of list valuation — multiply revenue per 1,000 by your list size to estimate what your list is worth.

Using Revenue Per 1,000 to Make Decisions
The metric shines in three decisions. First, list quality: a falling revenue-per-1,000 means your list is devaluing even if it grows. Second, acquisition: if a new subscriber costs you more than their revenue-per-1,000 value, your acquisition economics are broken. Third, segmentation: segments that clear the overall average are where you should send more frequently.
Combine it with revenue per email sent to separate list quality from engagement quality. A high revenue-per-1,000 with low revenue-per-send points to a small but valuable engaged core; the reverse points to a large list that isn't being monetised.
