## Why this rule exists

A consumer who wants to stop should not have to wait for the next message to find out how. Publishing both routes on the site is a CTIA expectation and materially reduces the complaint rate that drives carrier filtering.

## How to fix it

State on the site how to join and how to leave, naming the keywords: "Reply STOP to any message to unsubscribe."
