How to Block a Sender in Gmail

To have Gmail send messages from a specific sender to the Trash automatically:

• Follow the Create a filter link (at the top of any Gmail mailbox, near the search buttons).
• Type the desired email address under From:.
  • You can block an entire domain by entering just that. To block all mail from both natsuko@example.com and pjotr@example.com, type "@example.com".
  • To block more than one address, separate them with "|" (not including the quotation marks). You can block both natsuko@example.com and pjotr@example.com by typing "natsuko@example.com|pjotr@example.com", for example.
• Click Next Step ».
• Make sure Delete it is checked under Choose action.
• Click Create Filter.
  • Check Also apply filter to __ conversations below 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.

Add a New Address to Your Gmail Block List

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.
