What do you do when tamagotchi gets exclamation mark in mail?

When your Tamagotchi shows an exclamation mark in the mail, it typically indicates that it has received a letter or message. You should check the mail by selecting the mail icon on the device. Open the letter to see what it says, as it may contain important information, a gift, or a reminder about your Tamagotchi's needs. Make sure to respond or take appropriate action based on the content of the message.
