## Why this rule exists

A message is three words and a link, so the link is where the content actually lives — which is why Twilio's prohibited-content scope covers "campaign descriptions, sample messages, website content, and linked URLs" rather than stopping at the registered domain. The gap this closes is real and routinely exploited: a clean sample pointing at a dispensary menu, a sportsbook offer, or an affiliate page passes every check that reads text fields. It also catches honest senders, because a campaign link often lands on a partner or marketplace page that the brand does not control and has never read as a compliance artifact.

## How to fix it

Open every URL that appears in a sample and read the page a reviewer will land on, including anything it redirects to. Where the destination carries prohibited content, point the message at a page you control that does not — and if the prohibited content is the product, the campaign is not registrable on it. Done when every linked destination could be shown to a reviewer without explanation.

## Common mistakes

- Screening only the registered brand website misses this entirely: the finding is about where the message goes, and campaigns frequently link somewhere the brand record never mentions.
