You can keep a specific sender from sending emails to you by blocking, or sending their emails straight to a folder. Gmail also automatically identifies suspicious emails and marks them as spams.
Block a specific email address or sender
When you block a sender, emails they send will go to your Spam folder.
Note: This function does not work for internal emails, e.g. emails from domain @s.eduhk.hk. If you want to block an internal email address, please see Create rules to filter your emails.
- Log in your Gmail account at www.gmail.com.
- Open the email message.
- In the top right-hand corner, click the More button (the 3 vertical dots).
- Click “Block [sender’s name]”.
- If you have blocked someone by mistake, you can unblock them using the same steps.
