Meet Postbox

A better way to work with email messages and content.

Postbox lets you spend less time managing messages and more time getting things done. But what makes Postbox really useful is the way it lets you find and reuse all kinds of content hidden deep within your email. After all, it’s your email... make the most of it!

  • Image Search

    Direct Access to Files, Images, Links and More

    Use Postbox’s Content Tabs to instantly find attachments, images, links, and contacts – without having to dig through messages to find what you need. The Action Bar at the bottom of each search tab lets you do useful things from your searches, like create a new message from a document you’ve found.

  • Compose Sidebar

    Search within the Compose Window

    Get fast access to your email content when you need it most - writing messages. A handy Compose Sidebar lets you find attachments, images, and links directly within a new message window, which makes it easy to do things like resend project documents or incriminating photos from the company party. No more saving to the desktop, moving windows around, or other tedious actions that take up valuable time.

  • Contacts Panel

    Find by Contact

    Search for recent messages, attachments, images or links from your email contacts. Within the message header, click a contact to bring up the Contacts Panel, then chose which recent content type you would like to view from this person. Search results will conveniently open in a new tab. You can also search by contact from the Inspector Pane, accessible via the blue tab on the right side of the message header.

Smarter Message and Content Views

  • Conversation View

    Conversation Views Make Sense of Email Threads

    Postbox enables you to view and process messages by conversation. Simply select a summary row in your message list to see a roll-up of all messages within a conversation.


    Have fragments of a conversation scattered across your inbox, sent folder, or other folders? You can bring them all together, everything in one window, in one click.

  • Inspector Pane Summarizes Key Content

    Postbox looks for interesting content within each message, then highlights what it finds in the Inspector Pane. It's like a discovery engine built right into email. And if you’re looking at an entire conversation, Postbox summarizes everything that has been shared so far - all in one place.

  • Tabbed Mail Browsing

    Manage Multiple Windows Using Tabs

    Like a Web browser, Postbox lets you view your message content in tabs - enabling you to create an efficient workspace for everything you’re working on. Open almost anything in a tab, including messages, folders, searches, or content such as attachments and images. You can quickly switch between tabs, or even reorder tabs to customize your view.

  • Simplified Account and Folder Browsing

    Postbox lets you slice and dice your account and folder views in ways that reduce clutter and simplify your life. When you select an account, only the most relevant folders are displayed, which helps to minimize distractions from activity in other accounts. And since the location of your common folders is always preserved, it makes switching from one inbox to another a breeze.

Better Organization

  • Focus by Topic

    Organize Messages and Content by Topics

    Use Postbox to organize your messages by Topics. This allows you to focus your attention on one thing at a time, while minimizing interruptions from new messages outside of your current topic. A topic can be anything - a project, important client, an event, or even priority.


    To view messages by Topic, just select from your favorites in the Folder Pane. It’s like creating a mini-Inbox for just the messages you want to work on. Combine Topics with Search Tabs to find attachments, images, links, or a list of contacts that relate to the Topic in view.

  • Quick Tagging

    Easy Topic Creation

    Assigning a Topic is easy. Type in any word or select from a list of your favorites. Unlike folders (that force you to make decisions on where to file), you can assign as many topics to a messages as you like. And here’s the best part - when you assign a topic to a message, it gets applied to all other messages in the conversation, and all future message replies too.

Message Handling

  • Quick Message Archive

    Want to keep a message around but don’t want to bother with filing it? Just use Archive. One click and the message is moved out of your way and into a dedicated Archive folder. Don’t worry, you’ll still be able to find anything that you need by using Postbox’s powerful search features.

  • Edit

    Flexible Message Editing and Annotation

    Have you ever wanted to edit an email, or add a note, just as easily as using a word processor? With Postbox, you can work with messages like you’ve always wanted. Use the Edit function to change the subject message, edit its content, or add notes. You can even create a copy of your changes if you want to keep the original message, and everything will be grouped and displayed together in one conversation.

To-Do Tagging

  • To Dos

    Postbox provides a simple and lightweight way to use email messages to manage and track To-Dos. Messages marked "To-Do" are conveniently pinned to the top of your message list, so important work items do not get pushed out of view. Easily create new To-Dos and add them directly to your Inbox – no more emailing yourself notes! Use Postbox’s Edit feature to update the status of To-Dos, or focus your To-Do list by Topic.
