I spend a lot of time on Airmail, and I'm currently giving cloudmagic: https://cloudmagic.com/ https://cloudmagic.com/ a try. On iOS I've used it for a long time and they're excellent. On Mac I've only used them for a couple of weeks but so far it's been a good experience far, and they're responsive to feedback, like implementing gmail shortcuts shortly after launching.
