My take is that the built in iPhone email app is the best one you can get at the moment but if you are not happy with the iPhone mail app you can always pick one of the alternatives from the list below.

Be careful though not to spend the buck for nothing, read carefully the specs and what each mail app does. Would be a pity to get the same features you already have.

I think the best alternative for the email app is Email’n’Walk and I would use it a lot myself .. if I would not bike to work :P.

Anyway.. let me know if i missed any good one and enjoy.

Great concept…how about SMS? (by Jimmy Cudzilo)
This app is great for those multi taskers who just need to get that email sent but can’t take a break from whatever they are already doing. (Please don’t drive and email.)

I’d love to see this with SMS ability too!
Great (by Debra Sheridan)
It works really well and does exactly what it is supposed to do, but it would be FANTASTIC if you could also text.

Used to be great. Now crashes all the time! (by JenK26)
I’ve had this app for 2 years and used it daily. Loved it! Unfortunately in the last 2 months it has been crashing constantly upon startup or it just won’t refresh my inbox. Tried uninstalling and reinstalling the app and that only fixed the problem for 3 days before it happened again. Even with the latest x.x.4 update it still crashes. Useless app now.
Nice Application (by Kirihimete)
So I read all the reviews and decided to bite the bullet and pay the cost for this application. While I do agree this application is a little costly I think it could be justified by the quality of the application versus most of the other hotmail applications I’ve tried or seen. This application is very UI rich with a similar look and feel to the Microsoft Exchange application for iPhone.

The response times are quick for incoming mail and all the primary features are available in a very nice view modal. My conclusion is although the price is a little high, it is a great application for hotmail on the go.

Advanced email reader that helps you quickly act on and file your emails.

Do you use folders to save important emails?

Do you read email on your iPhone, but wait to act on it until you’re back at your desktop?

Do you wish you could add emails directly into your To-Do List or Calendar?

eMailGanizer’s signature feature is its ability to file emails with just 2 taps, no matter how many folders you have. eMailGanizer does this using sophisticated technology that learns your prior filing behaviour so that it can present you with the you with folders most relevant to the email being filed.

eMailGanizer does NOT work with POP.

eMailGanizer WORKS with any IMAP account.

Since eMailGanizer needs to learn your filing behaviours, the initial setup can take a while. An setup wizard will lead you through the process of entering your account information and the downloading will begin when that process is complete. For best results, you should be on a WiFi network.

Differences with pro version
This version of eMailGanizer shows advertisements and the pro version does not. The pro version shows bigger email previews and more folders on the screen at once.

You can upgrade to the Pro version from inside the app

This program is worth way more than than what is charged. Really glad I found it.

Thanks a million!

No email print (by FL Gooch)
Worked OK as a simple email app, but has a non-intuitive UI and the auto-categorization of folders did not determine correct folders. BIGGEST drawback was lack of ability to print emails. Deleted the app.

Just like web gMail and has chat and more (by RyanAggie)
Very well built app for gmail. It really turns the web version of gmail into a mobile version flawlessly. It has almost every feature that you have in your normal gMail. Also, since update I did on 6/15/11, the overlay buttons are now on bottom row of screen, eliminating the accidental tapping of buttons that used to lye in the middle of screen.
Decent App (by Mdmarshall75)
Not a bad app to track a second gmail account. Not nearly as good as the email app built into the phone though.
