Poppy is a small e-mail notification program that can check multiple POP3 accounts for new mail. It will display an icon in the taskbar, which will change whenever new mail is waiting. Poppy can also optionally play a sound, execute an external program or display a small popup window.

In addition to its main purpose, which is e-mail notification, it can also display the headers of individual e-mail messages, preview the e-mail message source and delete individual messages from the POP3 server.
