Abstract

Methods and systems for sending e-mail messages are provided. A sender of an e-mail pays a sending fee to the service provider for each e-mail sent. Each e-mail message includes a portion that is encrypted by the sender. If the recipient desires to read the encrypted portion, the recipient will request the corresponding decryption key from the service provider. The service provider sends the decryption key to the recipient, who can then decrypt the encrypted portion of the e-mail message for reading. The service provider refunds the sending fee, or some portion thereof, to the sender for each e-mail message for which the recipient requests the decryption key, while retaining the sending fee for those e-mails for which a decryption key was not requested.

5. The method according to claim 3, wherein the encryption key is further based on a time of sending of the e-mail message.

6. The method according to claim 1, wherein reducing the sending fee further comprises:

refunding at least a portion of the sending fee to the sender.

7. The method according to claim 1, determining if the recipient has requested a corresponding decryption key for the encryption key further comprises:

determining if the recipient has requested a corresponding decryption key for the encryption key within a predetermined time period.

charging the sender a first fee for delivery of the e-mail message to the e-mail address for the recipient if the recipient has not requested a corresponding decryption key for the encryption key within a predetermined time period; and

charging the sender a second fee for delivery of the e-mail message to the e-mail address for the recipient if the recipient has requested the corresponding decryption key within the predetermined time period, the second fee being less than the first fee.

11. The method according to claim 10, wherein the encryption key is based on the recipient'"'"'s e-mail address.

12. The method according to claim 11, wherein the encryption key is further based on a date of the e-mail message.
