Yahoo alert mail

You're referring to the classic "You've got mail!" alert from Yahoo!

In the early days of the internet, Yahoo! would send out email notifications to users when they received new messages. The notification would typically appear as a pop-up window or a banner at the top of the screen, with a message like "You've got mail!" or "New message from [sender's name]".

The "You've got mail!" alert was a distinctive feature of Yahoo!'s email service and became a recognizable part of internet culture. It was often parodied or referenced in popular media, such as in the 1998 film "You've Got Mail" starring Meg Ryan and Tom Hanks.

Although Yahoo!'s email service has evolved over the years, the "You've got mail!" alert remains a nostalgic reminder of the early days of online communication.
