# Running the pre-launch marketing compliance check
A single word sank a campaign. In 2022, a UK court and the Advertising Standards Authority took issue with fast-fashion "sustainability" edits that used vague green language without proof. The lesson for 2026: your prettiest hero image can become a liability the moment it makes a claim you cannot defend. This lesson turns that risk into a repeatable gate.
We will build a pre-launch marketing compliance check for a hypothetical seasonal drop: "Coastline," a 40-piece spring capsule going live across your webshop, paid social, and email.
A sign-off gate is a mandatory checkpoint where legal, brand, and marketing all approve assets before anything publishes. Nothing goes live until every box is ticked and named owners have signed.
The regulators you are answering to:
None of this is legal advice. It is a marketing discipline: prove what you say, price honestly, license what you show, and disclose what the law requires.
Every Coastline asset passes through four lanes. Assign an owner to each.
Substantiation means having evidence on file before you publish a claim. If you cannot cite it, you cannot say it.
Coastline examples and the proof each needs:
Build a claims register: a simple table mapping each phrase to its evidence and expiry date.
| Claim | Asset | Evidence on file | Expires |
|---|---|---|---|
| 60% recycled polyester | PDP, IG carousel | Supplier cert #RP-2291 | 2026-12 |
| GOTS organic cotton | Email hero | GOTS TC #A-8842 | 2026-09 |
| UPF 50+ | Swim PDP | Lab report LR-114 | 2027-03 |
If evidence is missing or expired, the claim is cut or softened. No exceptions.
The FTC's plain-language overview is worth bookmarking: Truth in Advertising.
Fashion lives on markdowns, and markdowns are where regulators catch brands. The core rule across the US, UK, and EU: a "was" price must be genuine.
In the EU, the Omnibus Directive requires that any advertised price reduction show the lowest price the item was sold at during the previous 30 days. So if your Coastline linen shirt sold at 45 EUR, dropped to 30 EUR for a flash sale, then you cannot later advertise "was 60 EUR, now 40 EUR." The reference point is the recent low, not an inflated origin.
UK guidance from the CMA follows the same spirit: reference prices must be real and reasonably recent.
Your pricing checks for Coastline:
Worked example. Your banner says "Coastline: was 80, now 48, save 40%." Check the math: 80 minus 48 = 32 saved. 32 / 80 = 0.40 = 40%. The percentage is correct. Now verify the 80: was it the genuine lowest price in the last 30 days? If it briefly sold at 55, the compliant reference price is 55, and the honest message is "was 55, now 48."
Beautiful imagery you do not have the rights to use is a legal bomb with a delay timer.
Checklist for every Coastline shot:
If Coastline used an AI-generated model, add: disclosure per platform policy, no implied real endorsement, and clarity that the person is synthetic where consumers could be misled.
Disclosures are the mandatory labels that keep an ad honest. Missing them is one of the most common enforcement triggers because they are easy to check.

Now combine the lanes into one gate for Coastline. The rule: no asset publishes until its row is green across all four lanes with a named sign-off.
Step 1: Inventory every asset. List each one. For Coastline that means 40 product detail pages (PDPs), 3 email sends, 12 paid-social variants, 1 landing pagelanding pageA standalone web page built for a single campaign goal, designed to maximise conversions by removing distractions and focusing visitors on one action.Voir la définition complète →, 6 influencer briefs. If it is not on the list, it does not launch.
Step 2: Run each asset through the four lanes. Use a status of Pass, Fix, or Block.
Step 3: Route fixes. A "Fix" goes back to the owning team with a deadline. A "Block" (for example, a claim with no evidence) is removed from the launch or held.
Step 4: Named sign-off. Marketing lead, brand lead, and legal or compliance each sign. Store the signed sheet. If the ASA or FTC ever asks, your audit trail is your defence.

A strong gate is boring on launch day because the fights happened earlier. The recurring failure modes to watch:
