I have 300 inbox messages and 291 spam messages in my Gmail. I need to delete all at one time and don't have time to click each message and delete them. I have 2 email account I have the same problem with both.
- From the menu bar at the top of the Gmail Inbox list, click the down-pointing arrow next to the rectangular-shaped icon and select All to select all of the email messages in your Inbox.
- Uncheck the 9, or however many there are, messages that aren't spam, one at a time.
- From the Gmail menu bar, click on the trash can icon to delete all of the messages that have been marked as selected by having a check mark in their checkboxes.
