I think you meant to ask "How to block an email in Mail.app on Mac?"

To block an email in Mail.app on Mac, you can follow these steps:

1. Open Mail.app and select the email you want to block.
2. Click on the "Mail" menu at the top of the screen and select "Block Sender" (or use the keyboard shortcut Command + Shift + B).
3. A dialog box will appear asking if you're sure you want to block the sender. Click "Block" to confirm.

Alternatively, you can also block an email sender by:

1. Right-clicking (or control-clicking) on the email in the message list and selecting "Block Sender" from the context menu.
2. Clicking on the "More" menu at the top of the screen and selecting "Block Sender" from the dropdown menu.

Once you've blocked an email sender, Mail.app will automatically move any future emails from that sender to the "Junk" mailbox. You can also set up Mail.app to automatically block senders that are marked as spam by clicking on "Mail" > "Preferences" > "General" and selecting "Block senders listed in the Junk Mail folder".

Note: If you want to unblock an email sender, you can go to "Mail" > "Preferences" > "General" and click on the "Unblock" button next to the blocked sender's email address.
