You're notified in a web browser, the desktop app, and on your mobile device, when you're @mentioned by your username or first name, @mentioned as part of a user group, and for matches to keywords you're following.
You're also notified when someone uses channel-wide @mentions including @channel and @all, as well as @here.
For all other messages, channels appear bolded to indicate unread activity.
Using a web browser or the desktop app, you can customize keywords to trigger notifications. Keywords aren't case-sensitive.
For example, you can receive notifications for all messages and threads related to a specific topic, project name, or customer.
<Tip>Separate multiple keywords using commas or by pressing <kbd>Tab</kbd>, and use <kbd>Backspace</kbd> to manage keywords.
</Tip>From Mattermost v9.3, Mattermost Enterprise and Professional customers interested calling attention to specific topics of interest across channels can do so without sending notifications to a Mattermost client.
Using a web browser or the desktop app, you can passively track key terms by specifying single or multiple words to be highlighted in all channels you're a member of. Keywords and phrases are automatically highlighted using a color based on your Mattermost theme.
