Add One-to-One Services -- Sherburne

You have customer data. You probably have customer data in several different places. Examine that data. Find out what you know—and don’t know—about your customers. Then try your own self-promotion campaign using multiple channels (including print).

Design it to fill the gaps in customer knowledge and to educate clients about the full range of services you can offer. If you can’t produce it internally, reach out to that potential partner. The best way to learn this stuff is to experiment on yourself. And, as a bonus, if you do it right, you will gain new business as a result.
