System Messages
System messages are automatic notifications that appear in a conversation when certain events occur. These are not sent by any user and are displayed differently from regular messages.
System messages are generated for the following events:
- A channel is created
- A channel name is updated
- A member is added to or removed from a group channel
- A User Group is linked to or unlinked from a channel
- A message is pinned or unpinned
Mentions
Mentions allow you to directly notify a team member or a group of team members within a conversation. When you mention someone, they will receive a notification drawing their attention to your message.
Mentioning a User
To mention a specific team member:
- Type the @ symbol in the compose area
- Start typing the team member's name
- Select the team member from the suggestion dropdown that appears
- Continue typing your message and send as normal
The mentioned team member will receive a notification alerting them to your message.
Mentioning a User Group
You can also mention an entire User Group. This will notify all members of that User Group who are also members of the current channel.
To mention a User Group:
- Type the @ symbol in the compose area
- Start typing the User Group name
- Select the User Group from the suggestion dropdown
- Continue typing your message and send as normal
Only members of both the mentioned User Group and the current channel will receive a notification.
Mention Notifications
When you are mentioned in a message, you will receive:
- An in-app notification within Astalty
- A push notification (if push notifications are enabled)
Channels where you have been mentioned will display a mention badge in the channel list, making it easy to find conversations that need your attention.
Reactions
Reactions let you respond to a message with an emoji without needing to type a reply. They are a quick way to acknowledge a message, show agreement, or express a response.

Adding a Reaction
To add an emoji reaction to a message:
- Hover over the message you would like to react to
- Click the Reaction icon (smiley face) from the message actions
- Select an emoji from the picker
Your reaction will appear below the message. If other team members have already reacted with the same emoji, your reaction will be grouped with theirs, showing a count.
Removing a Reaction
To remove your reaction, simply click on the same emoji reaction again. Reactions work as a toggle.
Viewing Who Reacted
You can see which team members have reacted by hovering over the reaction emoji below the message. A tooltip will display the names of the users who reacted with that emoji.
Pinned Messages
Pinning a message allows you to highlight important information within a channel so that it is easy for all members to find.
