Powerful, intuitive, and faster than a scalded monkey, the Postbox email client will help you stay on task, find information quickly and act, not react.

Postbox's Conversation Views are powerful, actionable, and easy to use.
It works by gathering conversation fragments from multiple folders and presenting them in a unified view.
So the rumors are true, Postbox will actually make you smarter.

Postbox Topics lets you organize your messages by keyword.
When you assign a topic to a message, it is also applied to other messages within the conversation, in addition to all future replies — a huge time saver.
Combine the use of Topics with the Focus Pane to attain a state of organizational bliss.

* If you don't have Gmail, no worries... because Postbox works great with any POP or IMAP email account,
including Yahoo!, Hotmail, MobileMe/iCloud, AOL, Comcast, Dreamhost, Rackspace, Zimbra and many more.

Quick Reply lets you reply to a message without the need to open a separate compose window, which is perfect for short, snappy responses.
It all happens within a message or conversation, so that you can get right back to what you were doing.
Use Quick Reply with Send and Archive to keep your Inbox tidy.


Summarize in Compose creates a beautifully formatted who-said-what-when digest that cleans up messy email threads.
Format your replies with profile photos, or just text for business use.
Either way, you'll look like a hero on each and every message send.

Our To-Do View lets you work on important tasks without distraction – within your Inbox!
Create new to-dos, annotate existing to-dos, and pin to-dos to the top of your message list so that they don't fall out of sight/out of mind.
Combine the To-Do View with Unified Inboxes/Folders and the Focus Pane to crunch through your workload in record time.

Postbox gives you fast access to documents and images hiding within your email messages.
No more digging through email messages to find what you need!
It's easy to save or send what you've found. Simply select a file or image, and click an action button.


The Compose Sidebar lets you search for documents and images while composing a message.
Open the Sidebar and start typing to begin your search. Then, drop what you've found into your message.
Reusing documents and images has never been easier!
It's hard to get excited about an email client, but @Postbox 3 for Mac is pretty slick.
@copey@postbox is killing it. It's like they kept everything right about Mail.app in Lion and got rid of all the mistakes. And made it handsome!
@dizziyneI started to evaluate @Postbox 3.0 the other day and can say pretty confidently that its pretty darn cool. Love the Evernote intgtn.
@andrewkordek@Postbox Version 3 really is a great improvement. Love the Dropbox integration and it opens fast. Great job and thanks.
