While most e-mail systems use folders to organize e-mails, Gmail (CNU’s e-mail provider) uses labels. Labels provide one key advantage over folders. While you can only move an e-mail into one folder, you can apply multiple labels to a particular e-mail.
Creating Labels
To create a label, click on the “More” link on the left side of your e-mail.
Then, click “Create new label”. If you don’t see it, hover your mouse over the list of labels and it will appear.
In the window that pops up, enter a name for the label. You can create labels “nested” inside other labels.
Your label will then appear in the menu at the left.
Assigning a Label to an E-mail
There are several ways to assign an e-mail a label. While viewing the e-mail, click on the labels icon and choose a label.
Then choose “Apply” from the menu. This will add the label(s) to your e-mail, but will not remove any existing ones.
If you click on the Move To icon, it will add the selected label to your e-mail and remove all others, similar to moving an e-mail to a folder on most other e-mail systems.
You can also drag an e-mail from your inbox to a label. This will remove the existing labels from the e-mail
How can I access labeled e-mails?
Simply click on the label at the left. The current label is in highlighted in gray by default.
How can I tell what labels an e-mail has?
When an e-mail has more than one label, any label except the current one will be displayed in the e-mail’s entry in the e-mail list.
When viewing an e-mail, all associated labels will appear by the title.
