Fetch mail from Inbox by Gmail or any third party mail app?

[techergy]

I signed up for the new Inbox by Gmail beta and am loving it. I installed it on my iPhone with iOS 8.1, though, one thing I wish I knew how to do was fetch mail like I've been doing with Apple's mail app. So, anyone know how to fetch mail from third party applications?

Any help will be greatly appreciated!

Thank you
