How to Flag a Message in Yahoo Mail
If you can’t deal with a new message in Yahoo Mail immediately, star it, or flag it, so that you don’t forget to follow up later.
To flag an email in your Yahoo Mail inbox, select the star beside the subject line.
To view your flagged messages, select Starred from the left side of Yahoo Mail.
Alternatively, you can flag a message while viewing it using Yahoo Mail keyboard shortcuts. To star a message you’re currently viewing, press the L key.
Star Messages in Yahoo Mail Basic and the Yahoo Mail App
In the mobile version of Yahoo Mail, you cannot star messages from the inbox. First select the message to view it, then tap the star in the upper-right corner.
In Yahoo Mail Basic, you can star messages from the inbox; however, there is no option to view starred messages.
