@mentions send notifications to specific individuals in the group or chat. They work like tags as a way to draw someone specifically into a conversation. To see who all available people are to @mention, type the “@” symbol on the keyboard in a message.
When @mentioned, the mentioned person receives a notification, ensuring that they are alerted to the message or conversation that requires their attention. Notifications can be received through the Heylo app via push notification, email, or both, depending on the member's notification settings. In all cases, the person will receive a notification in their notification center as well.
