You can synchronize most settings between your devices. eg. Email accounts, reminders, notification settings etc.

Open the app settings (View) - Email Management section and then you can turn the "Synchronize settings" on or off. If this setting is not available, make sure you have iCloud enabled on this device.

Your settings are synchronized and protected using your iCloud account.

You can clear all synced data from iCloud in the "Synchronize settings", but make sure you turn off syncing on all devices before you do this. Otherwise items such as reminders etc. will be removed from other devices.
