```
The environment variable `WATCHTOWER_NOTIFICATION_SKIP_TITLE` is required to prevent Watchtower from [replacing the `title` query parameter](https://containrrr.dev/watchtower/notifications/#settings). If omitted, the provided notification title will not be used.
Or, if you only want to send notifications using shoutrrr:
```
shoutrrr send -u "ntfy://ntfy.sh/my_watchtower_topic?title=WatchtowerUpdates" -m "testMessage"
