Every time you send an e-mail in Yahoo, it is automatically stored in the “Sent” folder. Yahoo saves all of your sent e-mail until you delete them and never automatically deletes anything. This means that you can pull up any sent e-mail from any time on your Yahoo account. It can come in handy when you need to resend an attachment or need to recall a conversation from long ago. However, if your wish to recall an e-mail, meaning get an e-mail back that you mistakenly sent, that cannot be done in Yahoo.
Open your Web browser and navigate to the Yahoo home page.
Sign In to your Yahoo account.
Click “Yahoo! Mail” to open your inbox.
Click the “Sent” folder on the left task pane. Browse through your sent e-mail for the one you need, or use the search function at the top of the browser window.
Select the sent mail to open it.
