Google have made updates to the tools used to block and unsubscribe from unwanted emails and newsletters in Smoogle.
Block and Unsubscribe in Gmail
Posted: 22 Sep 2015 11:31 AM PDT
To avoid disruptive emails and help people using Gmail stay in control of their inboxes, today we’re launching a new Block feature in the Gmail app on Android and the web. Future mail from blocked email addresses will go directly to Spam (and can always be unblocked in Settings).
In addition, the Unsubscribe option is now coming to Android, making it easier to opt out of eligible mailing lists and newsletters directly from the Gmail app.
