Email security, or the lack thereof, on many popular email servers gives privacy-focused people the creeps, which is why Yambuu Mail is taking email security to the next level. Yambuu's email app and server give its users absolute control over everything that has to do with their emails, using end-to-end encryption both on devices and in the cloud.
Aside from just encryption, Yambuu Mail users have a previously unheard of level of control over their email communication. The service lets users track the path of their email, not only to the original recipient, but also to any forwarded addresses. Users can then remotely delete the email if it has been forwarded to any undesired contacts. Emails through Yambuu Mail can also be set to expire, meaning they disappear from all recipients' inboxes after a set period of time.
