How to change Boxer Mail's notification sound on Mac

Discontinued client; alerts use system sound on legacy macOS.

The short answer: Boxer Mail doesn't expose notification-sound customization. Use the macOS-level method to mute it, or let Chirpy give it a custom sound.

Universal approach — mute at the macOS level

macOS lets you silence any app's sound without disabling its notifications. The full visual walkthrough lives on the universal macOS method page. The short version:

  1. Open System Settings → Notifications.
  2. Scroll to Boxer Mail in the application list and click it.
  3. Turn off Play sound for notifications.
  4. Boxer Mail keeps showing banners and badges — just no audio.
macOS System Settings → Notifications → Boxer Mail
System Settings → Notifications → Boxer Mail → toggle off Play sound for notifications.

Chirpy works with any macOS notification, including Boxer Mail's. Create one rule, pick a sound, save — done.

Want sounds that actually mean something?

Chirpy adds rule-based custom sounds on top of macOS notifications. One sound for Boxer Mail mentions, another for your calendar, silence for the rest.
