How to Star an Email
The simplest way to let Yahoo know that a message is important is to manually star it using the Star icon next to the subject.
How to Find Important Yahoo Mail Emails
Use the Sort filters to find email messages. For example, sort to see unread messages and hide emails that you opened. Or, find an email with an attachment you need.
Yahoo Mail’s Starred Category
Yahoo Mail also has a dedicated Starred category. This puts emails Yahoo deems as important into a special filter so that you can easily access those messages. It also automatically includes messages that you’ve starred.
Date: Newest on top: Newest emails show at the top of the list. Date: Oldest on top: If you’re looking for old emails or want to delete old messages, sort by date so that the old emails are shown first. Unread Messages: See all unread messages first, which might include emails you never opened or ones you marked as unread. Starred: View starred messages ahead of other emails.
To open the Starred category, select Starred from the left panel of Yahoo Mail. This category is part of the main list, along with the Inbox, Sent, and other top mail categories.
