How to Block a Sender's Emails in Gmail

Block a sender's emails in Gmail and have their messages deleted automatically without being bothered.

The Forwarding That Never Stops

So you made it to their address book. Five jokes forwarded by email each day do not lie.

Unfortunately, no convincing replies can, it seems, convince you out of the mass forwards. Your pleas for email silence are well received and benevolently ignored. Everybody wants to have and get some fun, right?

You Do Not Have to Delete Emails by Hand

Either way, you have to read the jokes, amazing stories, and virus warnings or delete them right away; or you can let technology do the job.

With a simple filter, Gmail can send all incoming email from your favorite forwarders to the "Trash" folder as it arrives. As an alternative, you can archive these messages and equip them with a label for later review.

Should You Not Use the "Spam" Button to Block Email?

It is best to reserve the Spam button for reporting junk email – mass mail sent typically for financial gain and from a source that is not easily identified.

For the single sender that keeps bothering you, it is usually better to block them. If you're receiving mailer daemon spam, read these tips.

Block Email in Gmail

To add a sender to your Gmail’s list of blocked senders and have their messages go to the Spam folder automatically:

1. Open a message from the sender you want to block.

1. Click the More menu button (sporting a triangle pointed downward (▾) next to the Reply button in the message’s header area).
   
   Note: It is easy to use the conversation More button instead, which is in the top menu and has "Menu" on it. Look next to the sender's name and picture.
2. Select Block "Name" from the menu that has appeared.
   
   Note: For some senders, such as Google itself, this menu item will not show. You can still employ a rule to "block" these senders; see below.

1. Click Block under Block this sender.

Looking to block a sender and have them receive a message you did when they send new mail? You can do so using a Gmail filter.

Block a Sender Using a Rule in Gmail

To have Gmail send messages from a specific sender to the Trash automatically using a filter you set up and maintain:

1. Click the Show search options triangle (▾) in the Gmail search field.
2. Type the desired email address under From:
   
   You can block an entire domain by entering just that. To block all mail from both user-a@example.com and user-b@example.com, type "@example.com".
   Tip: To block more than one address, separate them with "|" (the vertical bar; typically above the backslash on the keyboard; not including the quotation marks). You can block both user-a@example.com and user-b@example.com by typing "user-a@example.com|user-b@example.com", for example.
3. Click Create filter with this search ».
4. Make sure Delete it is checked under When a message arrives that matches this search:.

1. Click Create filter.
   
   Tip: Check Also apply filter to [__] matching conversations to delete previously received messages.

To archive and label instead of delete messages, choose Skip the Inbox (Archive it) and Apply the label: under Choose action when setting up the filter.

Of course, you can always unblock somebody you have blocked using a filter in Gmail – or whitelist an address altogether from being put into spam.

Add a New Address to Your Gmail Block List Rule

To add new senders to your block list, add them to an existing deletion filter using "|" (as above), or create a new filter if the From: field has grown big and unwieldy. You can find the existing filter by clicking the Settings gear in Gmail, selecting Settings and going to the Filters and Blocked Addresses tab.
