AnonEmail is an anonymous email service by AnonyMouse
The AnonEmail service allows you to send anonymous emails using a series of nodes. When you send your email using the service, it bounces through several random nodes, making it impossible to trace back to your IP address.
AnonEmail is easy to use. You fill in your recipient, the subject, and a short plain-text message, then “Send Anonymously.” Contrary to many other services, AnonEMail does not (appear to) log your IP address. When testing, it didn’t show or trace my IP address. However, I would strongly advise you not to send anything sensitive or illegal.
As an extra security measure, AnonEmail will wait for an unknown period before sending your email. The reason being that if further distances you from the email, disassociating you from the send time, send location, and any potential geographic presumptions based on timezones.
