Today, version 3.0 is hot off the presses. MetroMail 3.0 is so new you may not be able to find it in the Store yet. Luckily, we have the full scoop and Windows Phone 8.1 users will want to pay particular attention.

If you have to use Gmail for work, there are very few, if any, reliable email clients for Windows Phone beyond MetroMail . But besides Gmail, the MetroMail app also enables Outlook and IMAP with PUSH IDLE support for instant notifications. In other words, it's quite powerful and useful for those needing an app with "100% feature-parity with the official Gmail iOS app (minus server-side drafts)", or for those who need a potent IMAP client.

Before we get to the changelog, we should mention that the app is now free (with ads) for usage on one email account . That's pretty awesome if you want to give this a shot for awhile without forking over any money. Now on to the update…

If you have seen MetroMail in awhile, with a dark theme applied, the app looks very native for Windows Phone, which I'm sure many of you will appreciate. No worries though, you still have a light theme in settings if you preferred that look from before.

The Windows Phone 8.1 features are quite significant. Indeed, MetroMail may be the first app to download email previews via notifications. It's quite a nifty feature and makes this app much more powerful than before. The app itself is a lot more fluid, especially on a Snapdragon 800 device like the Lumia 1520 or Icon.

There're so many little features in MetroMail that are just eye candy e.g. touching the upper left corner in a message lets you see an overview of your email thread for easy navigation, or tapping the profile icon in the top right to switch accounts. Considering how powerful (and convoluted) Gmail can be, MetroMail does an excellent job of bringing over all of the main features of the service while maintaining a Modern look.

Although the Windows 8.1 Modern App version of MetroMail hasn't been updated yet, we're told that it too should be getting some update love in the near future, so stay tuned for that.
