Postbox 7.0

What's New

Themes

Postbox now ships with 20 beautiful themes spread across light and dark modes. To select a new theme, click the Themes button in the toolbar, or select a theme from the View > Theme menu.

The "Default" option will automatically switch between the original "Light" and "Dark" themes based upon the OS preference or dark mode state.

Clips

Clips let you quickly insert pre-formatted blocks of HTML into your messages. It works similarly to Responses and Signatures, but Clips have two additional capabilities:

  1. Clips can insert CSS into the <head> region of a message
  2. A default Clip can be used per identity when new messages are composed

This means that you can now create sophisticated newsletters, brand templates, or stationary and use them as needed or by default per identity.

Theoretically, any email template that you can create or find on the web can now be used in Postbox.

Like Signatures and Responses, we've included a suite of example Clips that you can use in your messages, including:

  • checked bullets
  • numbered bullets
  • buttons
  • callouts
  • description list
  • horizontal rules
  • image blocks
  • quotes
  • social follow blocks
  • text blocks
  • tables

To access Custom Clips, open the Compose window, make sure the Clips button is added to the Toolbar, press and hold the Clips button, then select Custom Clips from the menu.

Labs

Similar to add-ons, our Labs feature will allow for experimental 3rd-party code to be used within Postbox.

The first Labs project will be OpenPGP support provided by a specially designed version of Enigmail for Postbox and can be enabled under the Tools menu (remember to add the appropriate buttons to the Compose window toolbar).

Unlike add-ons which can be arbitrarily installed, only a select number of Labs projects will be available for Postbox. Given that Labs projects contain 3rd-party experimental code, they are not officially supported by Postbox, Inc.

If there's a 3rd-party solution you would like to see in Postbox, contact the 3rd-party developer directly. Please do not contact Postbox asking us to support code we do not develop, thanks! 👍

Cloud File Sharing for Business

By popular demand, we've added two new services to our Cloud File Sharing feature:

  • Dropbox for Business
  • OneDrive for Business

New Swipe Gestures on macOS

We've created a new swipe mechanism on macOS that will provide better feedback for four commonly used actions:

  • 1/2 swipe left = Archive
  • full swipe left = Reminder
  • 1/2 swipe right = Junk
  • full swipe right = Delete

The swipe actions work on a "swipe-n-hold" basis. Swipe until the desired action is displayed, hold, then let go once the swipe action "activates." This usage pattern was designed to prevent accidental swipes from performing an action.

Most importantly, swipe actions can be performed on multiple messages at once!

Currently, this feature is available on macOS only.

Quick Copy

This works similarly to Quick Move but copies the message to the desired folder instead of moving it. The keyboard shortcut "c" will bring up the Quick Bar, and from there you can type the name of the folder you wish to copy the message to.

Gmail Labeling Mechanism

We've created a new mechanism for Gmail labeling that mirrors the actions used for Quick Move, Quick Switch, and Quick Copy. Type the "l" key to bring up the Quick Bar, then autocomplete against the desired label name.

Gmail labeling works similarly to Topic assignment in the Quick Bar, and you can now assign multiple labels at once.

Highlight & Strikethrough in Compose

The compose formatting toolbar now supports text strikethrough and highlighting.

  • Add Prefix to Subject
