## Why this rule exists

Without an explicit acknowledgement the consumer cannot tell whether their STOP registered, and the rational response to that uncertainty is to complain to the carrier. The acknowledgement is what closes the interaction.

## How to fix it

State plainly that the consumer has been unsubscribed, in the past tense so it reads as a completed action rather than a request received.

## Example of a compliant value

```text
Acme Coffee: you have been unsubscribed.
