how to delete all mails in Gmail at once?
Unfortunately, there isn’t a convenient way to cut them right away. Instead of pressing a cool button, you’ll have to press and hold the Shift key. Click the first email, continue to hold down Shift, click the last email, and then hit Delete.
You may remove numerous emails from a folder without losing your read or crucial emails for later. To pick and delete one after the other, click the first email in the message list, hold down the Shift key while clicking the last email, then press Delete.
Go to the Inbox and open Mail. Select the emails you wish to delete from your Inbox by tapping Edit in the upper-right corner, individually selecting them, or choosing Select All. Tap Trash or Archive depending on your preference. If only Archive is visible, touch and hold it for additional options such as Trash Selected Messages.
To select everything on the current page, check the Select-all checkbox to the left of the Refresh button. To “select all conversations in to select everything in the current label,” click the link that appears. Delete is used to remove stuff from your computer.
Stop signing up for more emails. Stop getting new messages from your present providers. Delete any emails you won’t have time to read immediately. Use the sorting or filtering options offered by your email provider. For additional assistance, go online.
