90 marketing e-mails in my Bulk folder.Can not cope with and have no interest in such e-mail. Please help.?

I am gratefully requesting to rid me from marketing e-mails.They contain irrelevant commodities which do not suite my age group.As a Senior I do not have any interest in such commodities and hence I request that such e-mails be deleted from the Bulk folder.I just sent an e-mail to the address: answers-alert@cc.yahoo-inc.com requesting for help, but theMAILER-DAEMON@yahoo.com could not deliver the e-mail.Kindly help I do not want the marketing e-mails being flooded into my Bulk Folder.Kindly delete them.I am already grateful for your support and service for which I always owe.
