Junk mail is the wrong offer sent to the wrong person. The right offer sent to the wrong person is no less junk than the wrong offer sent to the right person-it’s another person that won’t buy.
As mentioned throughout this site, with the USPS reporting over 25% of direct mail being undeliverable as addressed, and a large part of the delivered mail actually being miss-delivered (per the definition of junk mail, above), please read, “How to buy a list” for some free advice on obtaining the most accurate and appropriate lists.
