In fact, not only will it send push notifications about emails, it will send them for RSS feed updates, Twitter or Friendfeed updates, and more.

A couple other features worth noting on Ultimate Notifier:

• Instead of reading the whole email, just see a summary and decide whether or not you want to read the whole thing.
• Set pulling periods for popular feeds, so the servers aren’t overloaded.
• Silent period that turns off the notifications during a specific time of day, so you don’t get woken up at night by an email.
• The app has its own API so devs can apply the formula to their own apps.

So far it sounds like it’s still in beta testing, so keep a close eye on it to be coming on the horizon soon. No word yet on pricing, if there is even any. I imagine it costing some small amount for the functionality you’re being given, but if executed properly this app will become incredibly popular quickly.
