I've been using email for many years and for many of us. I don't think that anyone needs any Spam mail, it is all junk and should not have been created in the first place. I think that part should be deleted forever. The blocking system does not work because it comes back into your email. It needs to be better run by the company.
We purchased Email Database for USA SAP Users andweare happy with the Serice and Data quality and we found them very professional and excellent customer service. So we are happy with the service of www.emaildatabase.us and we will work with them again as we got good results using their database
