It's an interesting concept, and I will always give a lot of credit for the sheer act of building something. But talk to us about the need and the use case here. Snapchat I understand -- but is there really a big need for self-destructing emails? If anything, the real problem in the email space is long-term storage and management.

I see the email space and the SMS/text space diverging into very separate use cases: email for long form communications that, if anything, are to be saved and filed; SMS for short-form communications that are disposable (literally, in the case of Snapchat, or figuratively). I get that there are long-form communications that are sensitive, and that we sometimes wish wouldn't stick around forever. But what proportion of all email conversations do we think this use case represents?
