Sparrow is a new email client for Mac OS X that sports a minimalist interface that feels surprisingly similar to Twitter. The application is currently available as a public beta with only Gmail support, but could turn into a viable alternative to Apple’s own Mail.app.
Sparrow’s email interface
The Sparrow application supports Growl notifications, viewing message threads, working with multiple email accounts, and drag-and-drop attachments. Support for IMAP email accounts is on the way, too.
The public beta of Sparrow is available as a free download at the Sparrow Web site.
