Are there alternative e-mail clients?

Hey, I'm really getting sick of Outlook E-Mail on my Mogul. I use two e-mail accounts, and I actually hate the fact that I need to keep them separate.

Also, the phone randomly tells me I have new e-mails (the notification up top pops up) even though I don't. So it's annoying having to open both accounts to make it go away.

Looking for an alternative e-mail program, also don't want to lose having a notification on the today screen that I have an e-mail.
