It's not easy introducing a new mail client. If people aren't already using mail.app, they'll be perfectly happy with webmail. The company that brought QuickMail, brings Outspring, a smart mail client, to beat the competition.
You can expect the typical mail features in Outspring Mail, including POP/IMAP, SMTP and SSL support, handling of drafts and templates, the ability to create smart mailboxes and keep separate accounts. Outspring Mail also includes a search function at the top right and a solid spam filter to keep your mailbox free of junk. The interface is quite similar to most mail clients although the icons could have been better designed.
Outspring has unique features that aim to make it smarter than other mail clients. The brain will learn from your actions and suggest similar ones to you in the future. However when we tested it it didn't seem to work properly all the time. We liked the 'message deferment' function to 'snooze' new incoming mail. Intelligent summary is supposed to be a smart way of showing a small review of new mail, however it turned out to be incoherent way too often.
The major drawback to Outspring is it's price. $95 is just too much to pay for a mail client, especially when you consider that Outspring still crashes every now and then. At such a price, you should expect something top of the range. Yet for free, you can already find excellent webmail clients or even work with a very solid mail.app.
The smart features certainly separate Outspring from the other mail clients. Unfortunately so does the excessively high price tag. Let's hope in the future Outspring becomes a bit more accessible.
