If you receive email from annoying sender and you want to get rid of it, Gmail offers an easy solution. You can quickly block the sender. All future emails from that sender will go in Spam folder automatically. You can unblock the sender any time from settings.
Gmail already lets you create filters to move emails to spam from a specific sender. But this block is just a one click solution and easier for all users who used to filters complicated.
Google has also added a similar option for newsletter emails. In place of block, you will see unsubscribe option for those newsletter emails.
This feature will be available on web and Android platforms in next few days. Google is rolling out it gradually, so it may take time in reaching you.
