If you are using Gmail and receive a lot of spam emails, you can filter them out easily. One way to mark emails as spam is to click Mark As Spam Button, but what if there are hundreds of spam emails and you want to delete them all instead of marking them as spam only. You can use the Gmail build-in filter tool to delete and block all such spam emails within seconds.
Go to Settings > Filter tab and click Create A New Filter.
Here enter the email address of the sender who is sending you the spam emails and click Next Step. You can leave all other boxes blank, it doesn’t matter.
In the next step check the Delete It checkbox and click Create Filter. This will delete all emails coming from the spammer.
