How to Mark a Message as Unread in Yahoo Mail

If a message is marked as read, but you want it to appear as unread, change it manually. There are two ways to do so.

Right-click the email message you want to mark unread and select Mark as Unread.
Alternatively, select the check box next to the message, select More, then choose Mark as Unread.
To mark multiple email messages as unread, select the Select Message drop-down arrow, choose All, then mark the email messages as unread.

Change How Long Until Message Is Marked as Read

The default Yahoo Mail settings will mark any opened message as read—eventually. How long it must be opened before being marked as read—if at all—depends on a setting. Here's how to change how long an email must be open before it is marked as read.

Log in to your Yahoo Mail account.
Select Settings (the gear icon).
Select More Settings.
Select Viewing Email.
Select an option in the Mark as read interval section. The options are:
- Immediately
- After 2 seconds
- After 5 seconds
- Never
If you select Never, emails remain marked as unread even after you have read them.
