What is the best email app on iOS for 20 email accounts?

I'm in need of an app that can manage around 20 email accounts that isn't the stock mail app. I would love to hear your recommendations!

    This one for sure! I switched to it couple of weeks ago and will never go back to stock mail app nor any other. Just give it a try!

    This is notably the best email client has seen on the iOS devices as it works so easily and the features are to die for
  2. Airmail is my pick for both iOS and MacOS. You can view a unified inbox or view each of your 20 accounts separately. More importantly, you can customize settings for each of your accounts individually.

    Thunderbird has more customization than any other Email client on macOS... If you're having trouble believing me then look @ mozilla.org/en-US/thunderbird/features/ If you're looking to fully customize your Email experience then use an open-source client. @mozilla
