Understanding the "read" vs “unread” status
Marking a conversation as read or unread applies only to you. This means that if you've marked a conversation as read, it will still appear as read in your view, but your teammates will still see the conversation as unread.
Front's unread messages have a blue dot to the left of the message, and the text is bolded.
Front's read messages get rid of the blue dot, and unbold the subject and body preview. A conversation is marked as read once you've read it.
To mark as unread, hover over the left of the message and select the blue dot on the left.
For individual inboxes set up via Gmail, reading a message in Front will mark it as read in Gmail.
For shared inboxes set up via Gmail, messages are marked as read in Gmail only when they are assigned to someone in Front.
