You can delete multiple Gmail emails by following these steps:
- Log in to your Gmail account.
- Check the box at the top of your inbox, to the left of the refresh button. This will select all emails on the current page.
- Click the blue text that reads "Select all X conversations in Primary." This selects all emails in your inbox, not just the ones on the current page.
- Click the delete button, which looks like a trash can icon.
