E-mail message

Most of us are not great at keeping up with the number of messages sent to our inboxes. While you can delete them individually or a few at a time, junk mail or infrequent account usage can necessitate the removal of thousands of messages. This page shows you how to clear all messages in your inbox (or other folders) at the same time. To proceed, choose your e-mail service from the list below and follow the steps.

Yahoo! Mail

By default, Yahoo Mail does not offer a direct option to delete a folder's entire contents, and only shows its first 40 messages. To delete more than 40 at once, you first need to scroll down in the folder to populate the list with all messages.
