What was the AOL "You've got mail" sound?

The AOL "You've got mail" sound was a familiar chime that played whenever a user received new email through America Online in the late 1990s and early 2000s. It was a simple, cheerful ding that signalled the arrival of messages. This sound became an iconic part of internet culture for many people who used AOL during its peak. Its simplicity and reliability made it instantly recognisable.
