Note2Email is a simple web service that lets you send email messages anonymously to anyone without signing up with the service.
When you write an email and send it via Note2Email, the service actually routes the message from its own servers and completely hides your IP from the message. This ensures that no one can track you even by your IP address. This will keep the email recipient wondering for life as to who sent the message and from which part of the world.
In addition to this the service also allows you to can use the service on a public terminal to send yourself an important note or a todo message without logging into any of your email accounts.
The service allows you to send unlimited email messages, but limits abuse by sending one message at a time.
