How to change Newton Mail's notification sound on Mac

Legacy client; alerts use the system sound.

Updated · May 2026·macOS Sequoia 15.x

The short answer: Newton 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 Newton Mail in the application list and click it.
  3. Turn off Play sound for notifications.
  4. Newton Mail keeps showing banners and badges — just no audio.
macOS System Settings → Notifications → Newton Mail
System Settings → Notifications → Newton Mail → toggle off Play sound for notifications.

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