Remove the clutter from previous email threads when replying by hiding quoted text in your replies. The app visually collapses text from previous email threads so you don't have to see it. You decide whether you wish to show or hide previous email threads from appearing. Here's how:
1.Tap the Nav icon at the top left corner of the Nav Bar to display the Navigation Drawer.
2.Tap the Gear icon at the bottom of the Navigation Drawer to bring up Settings.
3. Tap Mail.
4. Under the Message section, enable the Hide Quoted Text.
Note: If you deselect Hide Quoted Text, it will default to showing the original email.
