New Feature in GMAIL :Block,Unsubscribe Email Sender

Google has added a new feature to Gmail which will help you clean up your inbox . The two features are “Block Sender” and “Unsubscribe.” The block function is currently available via Gmail for web, and allows you to block people from sending you emails. When you block a email ID it will move all email to your spam folder, so you never have to look at them.
How to Block ?
In order to block someone, open up an email from sender, click the drop-down menu next to the reply arrow, and choose “Block Sender.”
Then it will ask for Confirmation that Incoming emails from sender will be moved to Spam.

The “Unsubscribe” feature is also very useful, and allows you to stop receiving promotional emails without having to navigate through complicated process to visit some third party website to unsubscribe
 “Unsubscribe” is available on Gmail’s updated Android app (along with “Block Sender”), so if you’re an iOS or web user, you’re out of luck for the time being. But if you are an Android user who wants to unsubscribe, go to the promotional email, hit the “More” option (represented by the three vertical dots) in the top right corner, and choose “Unsubscribe.”
