After 'undo', technology giant Google has now introduced 'block' and 'unsubscribe' features for its Gmail service that will allow users to block email IDs and unsubscribe from newsletters with a few clicks.
"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.
In June, Google had introduced the 'Undo' option that allows users to cancel delivery of an email within 30 seconds of hitting the send button, helping them avoid misdirected or inappropriate emails.
