I was getting fed up with Outlook today so had a scoot around the App Store and came across Edison
Installed and set up all my email accounts quickly and easily. Altered the swipe gestures, turned on Touch ID and it works wonderfully. So much quicker than Outlook.
You can mute notification for individual emails addresses, unsubscribe from them plus all the other normal stuff like delete, archive or move messages.
It also has an Assistant where you can see all your subscriptions, Packages due, travel info and more.
Really good app
