Twelve glass bottles in a box: fixing the parcel before the funnel

One order in nine came back, and the brand had spent a year reading those reviews as a product problem. They were not: almost every one-star review described the box, not the drink. The twelve-bottle case had been designed to sit on a shop shelf, where it is handled twice, and was being sent through a parcel network that handles it a dozen times and occasionally drops it.

The damage then compounded in two directions. Broken bottles ruined the rest of the case, so a single failure wrote off twelve units rather than one, and the refunds were charged against a product whose margin assumed almost none. Meanwhile the rating fell to 3.8, which made every advertising click more expensive to convert — the brand was paying more for traffic in order to lose it to a review about a leaking carton.

The whole engagement started with a parcel, not a campaign.

• Drop and vibration testing of the existing case, which failed at a fraction of the impact a parcel network routinely delivers.
• A transit-rated pack built for the journey — molded dividers, a corrugate grade that holds its shape wet, and certification so the case ships in its own container without a second box.
• Case count reconsidered — a six-bottle configuration added as the advertised hero, since a lighter parcel survives handling far better and suits a first-time buyer anyway.
• The packaging made visible on the listing, so shoppers reading old damage reviews can see what now arrives.

Damage-related returns fell from 11% to 1.6%, and unfulfillable units — the stock destroyed inside the network before it ever shipped — dropped by 89%.

Net revenue grew 66% while gross orders grew far less, because the account stopped refunding a tenth of everything it sold. The rating recovered to 4.2 within five months, and it did so without a single review-generation tactic: the negative reviews simply stopped being written, because the thing they complained about stopped happening.
