you may want to reverse your thinking....owners get so much crap in the mail, most is tossed out by receptionist before it hits the owners desk. Direct Mail is very expensive, you can only expect, at best a .5% response rate, (national average) probably less. Why not just call the owner (if this is the plan of your attack - I wouldnt do it) and say I mailed you information regarding (?) I just wanted to make sure it made it to your desk.... Whether you sent it or not, he will always say no....Then you can say; That is unfortunate, I spent alot of time researching your business, spent .45 cents on it, and the postman never delivered it...Figures....government... you really cant depend on govt to do anything can you.... (this way you are developing rapport and conversation with him)......Then say well let me do this...let me take 10 seconds of your time, see if you have an interest, and I will resend it to you if you see that we have a match..... just a thought
