DM in a B2B World

When thinking about the effectiveness of digital marketing, I began to wonder how impactful the field is in the business to business world.  For companies with lots of potential customers and a service that has a low marginal cost, such as SAAS companies, digital marketing seems to have a large value add. But I question how effective it is for a business like mine that is focused on a small subgroup of clients. Our business does not need thousands of clients, but instead a handful of very strong clients that use our resources extensively. Therefore, using digital marketing might not be very effective. On the other hand, while conversion rates will be low, the reward per conversion could be extremely high.
