Prefer your own alert instead of Webmail's default chime? You can upload a sound file to play when new mail arrives. This guide shows how, in Mailbox Options.
Step 1 — Open Settings
Click your avatar in the top-right corner and select Settings.

Step 2 — Open Mailbox Options
Select Mailbox Options from the Mail section of the settings sidebar.

Step 3 — Choose to upload a sound
Click Upload a sound file (blue) under Sound Notifications, then select your audio file (such as an `.mp3` or `.wav`).
Note: Upload a sound file opens your device's file picker to choose the file — that dialog belongs to your operating system, not Webmail.

Step 4 — Save your changes
Click Save Updates (green) to apply your custom sound.
