Children as young as 4 years old can safely exchange e-mail messages with family and friends using this simple, secure app. The browser interface is so kid-friendly that a preschooler can tap the app, compose a drawing using the artist tools included and choose a parent-approved contact to e-mail it to. Parents can be copied on all sent and received messages so they can monitor what is being sent to their children. Maily is very visual and includes options to add bright stickers and stamps to messages. Kids can take self-portraits with the iPad camera and add them to the e-mail as well.
