Fashion D2C
Try-three-categories cross-sell challenge
Goal , Lift basket size and category penetration without margin-eroding discounts. Move steady-buyers into a second and third category.
- Audience
- Existing buyers with 1-2 category history; not first-time visitors. Loyalty members or email-known segments respond best.
- Primary mechanic
- Challenge with three count-based objectives (one order in category A, B, and C inside the window).
- Support mechanic
- Optional per-step badge or unlock; final completion reward as the gate.
- Reward shape
- Tiered reward stack: small token at step 1 (free shipping or discovery sample), mid-value at step 2 (15% off next purchase), high-value at completion (cross-category voucher or curated bundle).
- Channels
- Email (3-touch series) · App push · Owned PDP banners · On-site logged-in homepage
- Timeline
- 21-day window. Cohort-launched (kick everyone in on day 0) so cohort comparisons are clean.
- Headline KPI
- Category penetration rate (% of cohort with orders in 3+ categories) vs. matched holdout. Secondary: 60-day repeat rate.
Common failure mode
Setting the threshold to power-user behaviour. If 21-day 3-category completion is < 8% of cohort, the challenge demoralises the median user; pull the threshold down before extending the window.
