Your IP address is not passed in the message header so your identity remain hidden and the email recipient will never know who exactly sent that message and from where.
Other than sending anonymous emails, this service will also come handy if you are sitting on a public terminal and want to quickly send yourself an email without logging into your own web account for security reasons.
You may send unlimited number of emails with Note2Email but one at a time. Obviously there’s potential for misuse so you can ask them to blacklist your email address so that people can’t send you messages anonymously.
