Mac OS X users are about to have a new option for a native Cocoa e-mail client—as long as they use the IMAP protocol and prefer a very spartan user interface. Called Sparrow, the app's developers recently launched a public beta to get some feedback on the features and design. With over 20,000 downloads in just one day, the developers are scrambling to massage the beta into a 1.0 release and answer the massive flood of user feedback.
We spoke with Dominique Leca and Dihn Viêt Hoà about their motivation to create a Mac OS X e-mail client, fueled by innovative iPad apps and frustration with vaporware projects. We also spent a little time with the beta of Sparrow to check out its Twitter-influenced user interface.
DIY Project

Leca cofounded an iOS development studio in Paris two years ago and hired Dinh, a former Apple software engineer, to code for the company. Two years later, both left to pursue other opportunities and decided to collaborate on Sparrow as a side project. Neither were prepared for the project to be so popular.
'We were amazed by the way Sparrow was received, and we weren't imagining that it could make so much noise,' Leca told Ars. 'We're gearing up to make a final 1.0 version of Sparrow, thanks to the amazing feedback we have had.'
When he was at Apple, Dinh had worked on iCal and later iSync. He was also heavily involved in the development of the open source e-mail library libEtPan.

Sparrow is an Android app and cannot be installed on Windows PC or MAC directly. Android Emulator is a software application that enables you to run Android apps and games on a PC by emulating Android OS. Sparrow Lite is an Email application for the Mac. You might be thinking why I will need an extra email if Mac OSX has provided me with the default mail application. Sparrow Lite is a lightweight mail application with the basic features that allows you to read your emails more comfortably and in a relax manner.
That library was used to build an open source Cocoa wrapper called MailCore, designed to be the basis of a Mac OS X IMAP client called Kiwi. Unfortunately, Kiwi has yet to materialize as an actual software product. However, both etPan and MailCore have been used in other Mac and iPhone e-mail clients, such as reMail and Notify. In fact, MailCore was considered as an option for another e-mail client project that was launched earlier this year called Letters.
Dinh had followed the early initial rush of work on Letters, but wasn't happy with the choice of MailCore. He felt that as the main developer of etPan he could make a better library, which he calls etPanKit, and planned to offer its use to the Letters project.
However, Dinh's offer was ultimately turned down. 'First, it was decided not to integrate this new engine and to write a new IMAP engine from scratch,' he told Ars. 'Secondly, Letters was going nowhere.' Ars confirmed that little progress has been made since the initial flurry of discussions got the Letters project off the ground in January.
With etPanKit in hand, and Leca offering to work on UI design and marketing (he has a business degree from French business school HEC), the pair decided to make their own IMAP e-mail client. And they forged ahead 'against most advice of Mac developers around us,' Leca said.
Advertisement'We kid a lot about it, but the Mac needs a great, alternative e-mail client, and in our coding fantasies we always talk about making the perfect one,' Panic's Cabel Sasser told Ars back when Letters had just been announced. 'What holds us back are only dumb, boring business things: it would take a lot of work, and we're not sure the return would be worth it.'
The problem most developers fear is competing with Apple and 'free'—Mail is already an adequate e-mail client for most users, and it comes free with every Mac.
But Dinh and Leca are prepared to put in the work to make Sparrow a viable alternative on Mac OS X. Leca said neither he nor Dinh have slept much since the initial beta was released earlier this week.
'Sparrow was a DIY project until it was released—the existing version is kind of a draft,' Leca told Ars. 'Now, given the way people have reacted, we'd like to 'professionalize' our approach and perfect the code and UI.'
Leca said that many users have been filing very precise, very useful bug reports, and Dinh has been working diligently to address them. The current beta is very limited in both features and server compatibility—in fact, it only works with Google's Gmail. Dinh told Ars that Gmail has some quirks in its IMAP implementation, but it's also very popular, so he decided to focus on compatibility there for the initial beta. Several feature requests are already being worked on for the next beta, too.
Like Twitter, for Gmail
The UI of Sparrow was heavily influenced by Twitter and Mail on the iPad. 'We felt that the iPad mail app was almost perfect,' Leca said, 'and that we would like to have the same one on the Mac.' He even asked Twitter developer Loren Brichter if the pair could use the 'magnificent' sidebar design from Twitter, and Brichter gave them his blessing.
If you have used Tweetie for Mac or Twitter for iPad, you can see the influence right away. The largish icon buttons along the left side let you access your inbox, starred items, sent items, drafts, and trash. Along the top, a row of large icon buttons lets you compose, reply, archive, or delete. And you can easily search through all your mail, wherever it's filed.
Your mail is then listed in a column, much like tweets are in many Twitter clients, showing who it's from, the subject, and the first two lines of the body. This lets you quickly scan your e-mail and address the most important items. Then you can double-click any e-mail in the list to open the full text in its own window. Alternately, you can expand the window with a button on the bottom right; selected e-mails open in a preview pane to the right. All the actions also have easy keyboard shortcuts, many of which are identical to Mail, making it easy to use without taking your hands away from the keyboard.

Right now preferences are very sparse. You can make Sparrow your default e-mail client, play a sound for new messages, and turn on Growl notifications. You can also add additional Gmail accounts, and switch between them using the sidebar on the main window.
Sparrow also includes a menubar icon. This turns blue when you have new mail, much like the menubar icon for Tweetie for Mac. From here you can bring Sparrow to the front or even directly open new unread mail.
The focus of Sparrow is to make e-mail a very minimal intrusion on other work, and to be a very simple and lightweight client. The design appealed greatly to Ars project manager Clint Ecker; if you feel, like he does, that 'e-mail is a poison,' then Sparrow's minimalist interface will definitely appeal to you. It encourages a workflow similar to the one used with desktop Twitter clients: check for new messages, quickly reply if needed, and get back to your other work.
Dinh has already implemented a few changes requested by users, such as adding a 'reply all' shortcut and adding any signature above the reply history (a behavior more common among most e-mail clients). The next builds will add additional keyboard navigation, support for Gmail labels, and add support for IMAP services from MobileMe, Yahoo, and more. Browsing support for archives—a feature already built into the code but hidden in the UI—will be coming soon as well.
Dinh says that at a minimum, he would like to add support for MobileMe and an option to connect to arbitrary IMAP servers, support for Gmail labels, improve performance, and quash any outstanding bugs to prepare Sparrow for 1.0 status. However, neither Dinh nor Leca are ready to commit to a solid launch date.
To be certain, the current beta looks very promising. If you've been looking for something as an alternative to Mail, and are a current Gmail user, we recommend giving Sparrow a try. As with all beta software, there are some bugs and rough edges, but you may find that its unique approach to keeping e-mail management to the bare minimum suits your style of work better than feature-heavy clients like Mail or Entourage/Outlook.
