How we prove what the work earned.

Most reports show what happened after the work. We show what happened because of it, in your own data, with a method your finance team can check.

Why most reports flatter the work

Most tools use attribution, which gives a campaign credit for anything a customer did after receiving it. Many of those customers would have bought, returned or renewed anyway.

Illustrative figures, to show the method. Not a client result.

An attribution report would credit the offer with 40. The real effect was 10. Decisions taken on the first number spend budget on customers who never needed the push.

The method

  • A holdout group, usually five to ten percent of customers picked at random, gets none of the new work for an agreed period. It shows what would have happened anyway.
  • Each larger campaign also gets its own control group: customers picked at random who skip that one campaign.
  • We count everyone who was picked, not only the people who opened a message, so engaged customers do not flatter the result.
  • We measure net revenue over thirty days, after every cost including rewards and discounts, and check the weeks after for spend that only moved earlier.
  • High value customers are spread evenly across the groups, so one large customer cannot decide the result by luck.

Your data, your numbers

We measure inside your systems, using your definitions, and agree the method with you in writing before anything starts. Every figure can be traced back to a saved query your team can run again. If a result is unclear, we say so rather than round it up.
