Here are the general steps to delete delivered emails:

2. Click on the "Inbox" tab to view your emails.
3. Select the email(s) you want to delete by checking the box next to each email.
4. Click on the "Delete" or "Trash" button (usually located at the top or bottom of the page).
5. Confirm that you want to delete the email(s) by clicking "OK" or "Delete" again.

Desktop Email Clients (e.g., Microsoft Outlook, Mozilla Thunderbird):

1. Open your email client and navigate to your inbox.
2. Select the email(s) you want to delete by checking the box next to each email.
3. Right-click on the selected email(s) and choose "Delete" or "Move to Trash" from the context menu.

Important Notes:

• Be cautious when deleting emails, as this action is permanent and cannot be undone.
• Some email providers may have a "Trash" or "Deleted Items" folder where deleted emails are stored for a short period before being permanently deleted. Check your email provider's settings to see if this is the case.
• If you're using a shared email account or have multiple users accessing the same account, be aware that deleting emails may affect other users' access to those emails.
