4. New look for Threaded Conversations
Mail has been able to thread the conversations for quite a while now, however, the introduction of iOS 10 sees a neater, sleeker new look, if you so wish! The upgrade allows you to select different messages from within the thread, without the need to leave the messages. To set up this feature for your Apple device simple go to your Settings > Mail > Threading. From there you can customise the display order of all of your messages.
