Claim Text:
1. A computer-implemented method for suppressing marketing emails comprising: encrypting, using at least one processor operatively coupled with a memory of a marketer computer, each email address and pattern of a first set of email addresses and patterns using an encryption scheme to create a first set of encrypted strings, wherein the patterns comprise regular expressions; sending the first set of encrypted strings to a remote computer; receiving a second set of encrypted strings from the remote computer, the second set of encrypted strings created using the first set of encrypted strings by comparing the first set of encrypted strings to a third set of encrypted strings to create indications as to which of the encrypted strings are included in both sets of encrypted strings, the third set of encrypted strings generated by individually encrypting each email address and pattern of a third set of email addresses and patterns using the encryption scheme; determining from an encrypted string of the second set of encrypted strings a corresponding unencrypted email address; and sending an email to the unencrypted email address.
