Context

ShopEase uses a binary classification model to predict which customers are likely to respond to a retention offer. The marketing VP wants a simple business-facing summary of model quality because the team is deciding whether to use the model for a campaign with limited budget.

Current Performance

The model was evaluated on a holdout set of 20,000 customers, with 2,000 actual responders (10% positive rate).

Metric	Value
Accuracy	0.89
Precision	0.62
Recall	0.78
F1 Score	0.69
ROC-AUC	0.86
Threshold	0.40
Predicted positive customers	2,516

The Problem

The business audience is not technical and tends to focus only on accuracy. However, the retention team cares more about reaching likely responders without wasting too much budget on customers who would not respond. You need to explain what these metrics mean in practical terms and whether the model is good enough to launch.

Requirements

Summarize the model's performance in business language using precision, recall, and ROC-AUC.
Explain why accuracy alone is potentially misleading in this case.
Interpret the current threshold choice and the tradeoff between precision and recall.
Recommend whether to launch now, adjust the threshold, or run additional validation.
Describe what one slide or short verbal update to executives should emphasize.

Constraints

Marketing can contact at most 2,500 customers in the first campaign wave.
Each outreach costs $4.
Missing a true responder has moderate revenue impact, but contacting non-responders wastes budget and may increase unsubscribe risk.
