Measurement
Proof, not applause.
Opens and clicks don't pay rent. Every Engage campaign is measured against a control group — so you see the revenue that happened because of the campaign, not just around it.

The problem
Open rates never paid a supplier.
Most campaign tools celebrate attention. But guests who would have returned anyway open messages too. Without a control group, "results" are just correlation with a nice chart.

The dashboard
One screen. The whole truth.
Window, audience, costs, control group and net lift — fixed before launch, reported after. No cherry-picking, because the rules were set before the first message went out.

Methodology
The group that gets nothing proves everything.
Before launch, Engage randomly sets aside a holdout group — 1–50% of the audience, 5–10% is the practical sweet spot. They receive no messages. After the window closes, we compare buying behavior of the two groups. The difference is your lift.
- 01
Random split at launch — no bias, no self-selection
- 02
Same window for both groups — 7 days default, up to 90
- 03
Net after costs — gift redemptions and message spend subtracted
The report
Fixed before launch. Reported after.
Audience tracking
Orders, buyers and net revenue of the exact guests messaged — not blended store totals.
Gift costs
Every redeemed gift counted at real redemption value.
Message costs
Per-channel spend via Infobip, down to the message.
Holdout comparison
Control group behavior over the same window — the baseline for lift.
Incremental net
The only number that matters: extra profit after all campaign costs.
