Few users are very particular about their mailbox, they never left unread posts. However the majority of users surf their posts and read which they want to. Certainly, one or more than one your emails scuffled down in the record and latterly, perhaps you really need that one.

From now there will be a change in Mail app in iOS 10 with which users can easily find their unread mails.

First open the mail app in your iOS 10 then tap the round tiny button in the bottom left of your screen, it will turn blue. After this users read mails will disappear and now users can create smart mailbox for unread mails, it will be easier and much faster. Users can compose new mails and also search but the variation is that user’s unread mails are filtered.
