In order to delete thousands of emails in Gmail, you can press the “Delete” button next to any email. This will send the email to the trash folder, where it will stay until you delete it from there.

There are no ways to delete inbox mail all at once. You can delete individual messages or delete them in bulk.

To delete more than 50 emails at a time in Gmail, you can use the keyboard shortcut “Shift+Delete” or “Ctrl+Shift+Delete” to select and delete all of the emails in your inbox.

To bulk delete in Gmail, you can use the keyboard shortcut “Shift + Delete” and select the emails you want to delete. You can also go to “Settings” and select “Labels.” Click “Create new label” and give it a name like “Delete.” Once you’ve created the label, click on it and all of your emails will automatically be labeled as such. When you’re ready to delete them, just click on that label and then select “Delete.

You could try batching emails into categories and deleting the bulk of them in one go. For example, if you have a set of emails that are all related to a specific project, then you could move those emails into a folder and delete them all at once. You could also use search functions to find and delete any email with certain words in the subject line.

This is a difficult question to answer without knowing more about your specific needs. However, if you are looking for an email client that allows you to delete emails in bulk, the best option would be Gmail. Go to Settings > Filters and Blocked Addresses > Create a new filter, then enter the criteria for your search (e.g., unread) and select “Apply the label” with “no label.” This will create a filter that only applies to unread emails.
