Downloading Postbox for macOS

You're almost there...


Installation Instructions

  1. Download Postbox to your desktop or folder of choice (if your download doesn't start automatically, click here).
  2. Double-click the DMG file, read and accept the license agreement, and then drag the Postbox icon to your Applications folder.
  3. If a previous version of Postbox is already in your Applications folder, simply overwrite it (don't worry, your mail settings, databases, and other files are stored in a different location).
  4. Start Postbox, and you will be presented with two choices:
    1. Migrate from an earlier version of Postbox 3, 4, or 5. This will copy your settings over from a previous install.
    2. Clean install, does not copy any data, you'll be setting Postbox up from scratch.

For full installation details, please see our Postbox 6 Migration Guide.
