Sometimes you get mail from someone who’s really disruptive. Hopefully it doesn’t happen often—but when it does, you should be able to say, “Never see messages from this person again.” That’s why you can now block specific email addresses in Gmail—starting today on the web, and over the next week on Android. Future mail will go to the spam folder (and you can always unblock in Settings).
In addition, the unsubscribe option is now making its way to Android, so you’ll be able to opt out of eligible mailing lists directly from the Gmail app. It’s perfect for those newsletters you subscribed to a while back but don’t read any more.
So try block or unsubscribe when the situation calls for it. And stay in control of your inbox.
