Alternative email client for ipad/iphone

[opethdisciple]

The default email client on the ipad is not very good.

There is no way to collapse folder structures, meaning that mail boxes can take a long time to scroll through.

Are there any better alternatives, with collapsable folders?

The problem is this is for business use.

Our staff are complaining that they have to scroll through 100's of sub folders, when they would just like to collapse them as they can in Thunderbird.

I cant believe that this is not possible on the ipad.
