One of the top selling Mac email clients is now available in the Mac App Store. Sparrow, which calls itself “the new mail for mac,” is priced at $9.99.

Sparrow currently works with Google mail. An upcoming update will offer IMAP support for most mail providers, including Yahoo!, AOL, and MobileMe.

The client’s biggest strength is its minimalistic approach. However, don’t be fooled by its simple interface. It actually does quite a lot.

Sparrow includes the ability to add multiple accounts, and its thread feature makes flicking through emails quick and actually quite fun.

Plus, its Label option keeps mail free of clutter.

Finally, images are quickly added to emails using a simple drag & drop approach.

Sparrow is a great mail client. Get it today in the Mac App Store.
