Are there any email app add-ons, that work with existing email accounts setup on my phone, to help organize and notify me of emails? I have a work phone with exchange, but can't add the exchange account anywhere else, so I'm stuck using the preconfigured exchange account in IOS. Are any of the other email apps able to use this setup to process my email? What I'd really LOVE is an app that can send notifications (via email or SMS or something else) to another phone? (not looking forward to carrying two cell phones)
