Our email triage tools make managing your inbox feel like pure magic.

Use Quick Actions like email wizardry.

Get to Inbox Zero using Postbox's incredible Quick Bar. It's like Spotlight on the Mac but built for everyday email actions. Move or copy messages, switch folders, tag or label messages, or navigate across folders with just a few keystrokes.

Move mountains of messages in minutes.

Postbox supports a full suite of keyboard shortcuts, an extensive set of filters/rules, and intuitive swipe actions on macOS to dispatch messages in a flash.
