Gmail displays a column of arrows, that it calls personal level indicators, next to the messages listed in your Gmail interface. These arrows allow you to tell if each message was addressed to you, a group, or a mailing list.
- A single arrow > appears next to a message when it is sent to you and to a group of others.
- A double arrow >> shows that the message was addressed only to you.
- No arrows will appear next to messages that were sent to a mailing list.
You can choose whether to enable personal level indicators (they are enabled by default):
- Click the gear wheel in the top right of the interface and select Settings.
- Select Show indicators in the Personal level indicators: section to enable the option, or No indicators to disable it.
- Click Save Changes.
You’ll also notice that some of the messages are marked in yellow; these are messages that Gmail has ranked as important, and which I’ll discuss in an upcoming post.
