It's a lovely idea of you writing to your son, and I thought about doing the same a while ago. Meanwhile, I've sent him real postcards from business trips. I think there is nothing wrong with creating an e-mail inbox for a kid, but if you write personal messages and attach photos, I think self-hosting is the way to go, because you don't know how much Linus (or any other kid) will value his privacy once he learns about how the world works (from advertising to government surveillance). My wife and I therefore decided there will not be a photo online of our child until he can consent to it himself.
