A new kind of messaging application, the Postbox™ email client automatically analyzes your e-mail messages, documents, photos, and links to web pages; then it catalogs all this information making it faster to search for and retrieve.
Tagging features let you organize messages the way you want and then focus on one project at a time without missing out on important new messages. You can also view messages by conversation, edit messages, and create to-do items that appear in mailbox windows.
Available for Mac and Windows-sorry, no Linux yet. See a complete description ofPostbox features here.
The Beta is free. Future pricing has not yet been determined.
