Inquiries most often go quiet because of slow response, unclear fees, or scheduling friction. Replying within one business day, stating fees in the first reply, and offering a direct booking link recovers a significant share of inquiries that would otherwise never reach a first session.
Most half-full practices do not have an inquiry problem. They have an intake problem, and the leak sits between first contact and first session.
Three causes account for most of it:
Two habits recover most of what leaks. An automatic acknowledgment that states your response time buys you the day you need. And one gentle follow-up two or three days later, framed with an offer to suggest other options if you are not the right fit, which is what makes it feel safe rather than salesy.
