Penguin Mail

Penguin Mail was introduced on May 29, 2008. Instead of postcards being only a one time use, it allows you to manage postcards as mail and even send reply or send mail to penguins, but you can only reply to penguins on your buddy list. To see a list of messages, click here. The first postcard all players got was an introduction to Penguin Mail which also gave away a free Blue Mailbag.

Players can recycle messages via the recycle button, to lower their usage of the allowed inbox. There was once a trash button. However, it was permanently changed during the Earth Day 2010 so that it would be recycled. Also, players can directly reply to the sender of the postcard, and the receiver can inherit the postcard even if they are offline. Players may occasionally get automated postcards for events such as adopting Puffles or joining Club Penguin. A postcard was also given to Members during the Music Jam 08 telling them to look for the Penguin Band. A similar postcard was sent during the Penguin Play Awards telling penguins to look out for The Band and Cadence at the Stage. The Penguin Mail postcard catalog updates every month or so.

Trivia

You can send mail to the system by clicking "Reply to buddy" before it hides above the screen. However, their mailbox is always full.
The Candy Cane Hat, Holiday Toque, Springy Santa Hat and Blue Mail Bag could be obtained through Penguin Mail.
