# July 2023 - Version 3.42.3

## Bug Fix

### Description

When a recipient texts “Stop” back to the sender, the recipient receives an opt-out confirmation message, but the `Do Not SMS` checkbox on the Contact record is not updated. The sender in this scenario has the Blackthorn Messaging Standard User and Blackthorn Messaging Lightning User permission sets.

### Resolution

The `Do Not SMS` checkbox on the Contact record will be automatically set to “True” when the recipient replies “Stop.”
