When is a good age to begin emailing?

This is an email to Evelyn from her four year old friend. It cracks me up!

Evelyn,

Thinking of you,

Evelyn loves to type on the computer, as well as Karlee, but I never thought to have her send an email. Maybe we'll have to get her her own email address soon...ahhhhh!
