For a simple stay in “touch” with the potential client campaign, can’t you mail oversized postcards monthly? The message on the postcards is simply client testimonials in story form.
Example: Picture of building on fire on one side.
Words on address side. “My heart raced when the phone rang at 2:40 AM and the voice on the other end excitedly said my 100 year old building was on fire. I jumped into my clothes and as I zoomed downtown, I wondered whether to call Bill, my insurance person for 8 years. Hey, I thought, I had never called him to wake him up, no better reason than this.
To my complete surprise and relief, Bill beat me to my building. I felt somewhat foolish when I saw Bill. What could he do? Then it dawned on me. Bill cared. He cared enough to assure me things were going to start rolling toward a solution.
…The city and country caused the problems. My insurance and Bill’s attention to detail were as perfect as I could have hoped.
