How to Block a Sender in Gmail?

If you are annoyed of receiving email from a sender or you just wish not to receive any mail from a sender, you will think of blocking a sender. In Gmail, you will not be able to block messsages from a sender directly. But, you can set up a filter to send those unwanted messages directly to Trash.

To set up a filter, follow these steps:

Click Create a filter under the search box at the top of any Gmail page.
Fill in the appropriate fields with the filter's criteria, and click Next Step.
Choose the action you'd like for these messages by checking the appropriate box. (In this case, Check Delete it.)
Click Create Filter.
To edit or disable a filter, click Settings at the top of any Gmail page, and open the Filters tab. Check the filter you wish to disable and Press Delete.
