Greetings, I just discovered today that by calling the vendor who mailed the direct mail marketing literature, you can find out who provided them with your name and mailing address. You can then in turn contact that source and ask them to remove your name and address from that list. -- ITZ
You can also do something similar with SPAM e-mail as well. Do a "whois" search on the domain that is sending out the SPAM. You might need to do a bit of sleuthing in the mail header to figure this out. From the "whois" records, you can find the administrative contact of the whoever owns that domain name. -- ITZ
ITZ, What I found helped was to be taken off the credit card companies unsolicited mail list. The credit agencies like Equifax have an 800 number where you can opt out of unsolicited card offers. The other thing I have done is send the postage paid envelope back with the address asking to be removed. If I get a second letter from the same company (after a nice request) the envelopes are good for disposing of other junk mail.
