I tried Mudlick per the recommendation of a friend and marketing professional. I changed what I was doing amidst several competitors opening up inside of a mile of my shop within a year. My car counts are down 25%. I have done two mailings with them and have seen less than ten come in with our mailer offer, have logged 12 calls from offer recipients, and have not improved my car counts in the least. I would like to continue but at over $3k per month to send these out (6,000 mailers) I can't afford to keep hoping. I'm going back to my customer base and inserts in my local paper that always drive customers. Sure, we get some oil change only customers but we convert many of these customers to higher tickets in time. I also feel that if I do a good job on oil changes and this customer is pleased they will tell others to come to my shop for service. Somewhere in that referral chain is a great customer or two.
