Sample messages must be materially different from one another

The requirementstatement

Why this rule existsrationale

The point of multiple samples is to show a reviewer the range of what will actually be sent. Three variations on the same sentence demonstrate nothing about the rest of the program, so reviewers read near-duplicates as padding to satisfy a field count and reject the campaign as unrepresentative. Exact-duplicate detection catches only the laziest version of this; the common failure is three messages that differ by a product name.

How to fix itremediation

Replace near-duplicate samples with messages covering genuinely different scenarios from the same campaign — for a marketing campaign, one promotion, one product launch, one loyalty or event message rather than three discount offers.

A compliant exampleexample

1. "Acme Coffee: 20% off all beans this weekend. Shop https://acmecoffee.com/sale Reply STOP to opt out, HELP for help."
2. "Acme Coffee: your rewards balance is 240 points — enough for a free drink. Reply STOP to opt out."
3. "Acme Coffee: our Mission St store opens Saturday at 8am, first 50 customers get a free pastry. Reply STOP to opt out."

Common mistakespitfalls

Changing only a discount percentage or a product name between samples is not material difference.
Do not solve this by making one sample an opt-out confirmation — samples must show campaign content.
