Abstract
A system for communicating email messages using tokens receives a request to send an email message to a receiver. The email message is associated with a sender's email address. The system determines whether the sender's email address is associated with a token from a plurality of tokens stored in a token-email address mapping table. The system generates a particular token for the sender's email address in response to determining that the sender's email address is not associated with a token, where the particular token uniquely identifies the sender's email address. The system sends the email message using the particular token instead of the sender's email address, such that the sender's email address remains anonymous from the perspective of the receiver.
