Second that. Email is insecure, so whose eyes can see it is my first thought.

Thanks for the comment, currently they're hosted on S3 but I toyed around with the idea of having a downloadable application that syncs the emails to your own device and deletes them from the server. Is that something you'd find valuable for the sake of privacy?

I will work to address the TOS soon, good thinking.

Having my own domain I tend to just make up email addresses as I need them. Not too anonymous though, given whois. Anonymity has not been a issue for me I suppose.
