How to block email from someone

Updated April 17, 2017

Unwanted spam or marketing email messages can fill your email inbox and swamp the important personal or business emails that you need to read. One way to keep your email inbox clear of unwanted messages is to block the sender. Most online email services and programs include a junk email feature you can use to block unwanted email messages from a specified sender. After blocking the sender, your email service or application will stop delivering messages from that person's email address to your inbox.

Microsoft Outlook

Launch Microsoft Outlook.

Click the "Home" tab on the program's main menu ribbon.

Select "Junk" in the Delete group, and then click "Junk email options."

Click the "Add" button below the "Blocked senders" tab.

Type the email address of the person you want to block in the "Add address or domain" field.

Click the "OK" button to add the sender's email address to the block list.

Yahoo! Mail

Sign in to your Yahoo! Mail account.

Click the "Options" button in the top right of the page.

Select "Spam" from the list on the left.

Scroll to the "Blocked addresses" section in the middle of the page.

Type the email address you want to block in the field.

Click the "Add" button to block emails from the address you entered.

Windows Hotmail

Sign in to your Hotmail account.

Click "Inbox" in the menu on the left.

Click to select the check box next to any email message from the person you want to block.

Click the "Junk" tab on the main menu at the top of the screen.

Google Gmail

Sign in to your Gmail account, and then click the down-arrow button in the search field at the top of the screen.

Enter the name or email address of the person you want to block in the field in the search criteria window.

Click "Create filter with this search," and then click to enable the "Delete it" check box.

Click the "Create filter" button. Gmail will now automatically search for unwanted emails from this sender and automatically delete them.


If you change your mind and want to receive email messages from the blocked sender again, remove the person's email address from the blocked senders list in the junk spam section of your email program or service's settings screen.
