Yahoo Mail on Thursday introduced several new updates for iOS and Android operating platforms that are focused on allowing users to add personal touch to their inbox. Yahoo now allows iOS users to take back an email right after it’s been sent. After you press send, an option to “undo” will appear at the bottom of your inbox feed for three seconds. Just click that and you’ll stop the email from sending. Using “Xobni” technology, Yahoo will now give iOS users options to search for a person in mail, the company said in a statement.
