Every unreturned lead is money you already spent.

An unreturned lead stays on a practice’s books because the marketing that produced it was already paid for. When nobody calls back, the practice writes off that spend and the expected value of a new client at the same time. In behavioral health, the practice usually loses the person too, because reaching out took real courage and they’ve often moved on by the time anyone calls.

I spent a lot of September talking about the first phone call and what happens after it. This week I want to talk about the call that never happens. It’s the quietest failure in a practice, and it doesn’t announce itself. A voicemail sits unreturned, and a person stops waiting.

And because it’s quiet, it rarely shows up anywhere an owner would look.

Why does an unreturned lead belong on the balance sheet?

You paid for that lead the moment it arrived. Ad spend, directory listings, the website, and the content that earned the search all went into making that phone ring. Whether anyone picks up afterward has no effect on what the lead cost. It only decides whether the practice gets anything back.

Most owners think about leads the way they think about the mail. Some of it’s useful, some of it isn’t, and whatever you don’t open seems free.

Here’s the thing. That inquiry was purchased. Let me show you with round numbers, for illustration only. If a practice spends $6,000 a month on marketing and gets 80 inquiries, each inquiry cost $75 before anyone picked up the phone. If a new client is worth about ten sessions at $100 each, and the practice usually turns 40 percent of its inquiries into clients, each inquiry carries about $400 in expected value.

At those numbers, ten unreturned inquiries a month means $750 in marketing spend with nothing to show for it, and about $4,000 in expected client value that never arrives. Every month. Almost none of it shows up in a report, because the report counts leads and the bank account counts clients.

Your numbers will be different, and they should be yours. Pull your own spend, your own inquiry count, your own conversion rate, and your own average sessions per client. And that math leaves out everything that doesn’t fit neatly in a spreadsheet, like the friend or family member that client might have sent your way a year from now.

We walk through the full method in What Does an Unreturned Inquiry Cost a Practice?

“An unreturned lead is a purchased asset you threw away. You paid for it the minute it arrived, whether anyone called back or not.”

What does an unreturned lead look like inside a real practice?

A voicemail that got heard and set aside. A form fill nobody opened. More often than not, it’s a callback that gets pushed to tomorrow because the person who’s supposed to make it is also checking in patients, running sessions, or covering for someone who’s out.

Last month I wrote about a lead-by-lead review we did with a client who was frustrated that her marketing wasn’t producing new clients. As we went through every lead together, the same story kept coming up. Some calls weren’t returned for a week. Some were never returned at all. The form fills were essentially never answered.

She wasn’t careless. She was stuck between a rock and a hard place, in session when the phone rang, with everyone else in session too, and losing sleep over the calls she couldn’t get to.

Then there are the inquiries that arrive after hours. A form submitted at 9:40 on a Sunday night sits until Monday, and Monday already has its own pile. By the time somebody gets to it, the person who sent it has had a whole night and a whole morning to keep looking.

When a group practice we work with tells us the marketing isn’t producing, the callback is one of the first places we look. We see versions of this all the time. A first callback reaches voicemail, somebody logs the lead as “contacted,” and nobody tries again. On paper, the lead was handled. In real life, nobody ever spoke to the person.

The pattern shows up in national data too. CallRail’s analysis of 1.1 million calls, released in January 2025, found that health businesses missed 32 percent of their calls, the highest missed-call rate of any industry it measured. Almost a third of the calls, in the field where picking up the phone is hardest for the caller.

If you want the broader list of reasons inquiries stall between the ad and the appointment, we’ve covered why marketing leads don’t turn into clients in detail.

Why don’t people who reach out to a practice try again?

Reaching out the first time took real effort, and by the time a practice calls back, the search has usually taught the person to keep moving. Many are contacting several practices at once, and the first one to offer a real conversation and an appointment usually gets them.

Start with how hard that first step is. Among U.S. adults with any mental illness in 2024, 52.1 percent received mental health treatment in the past year, according to SAMHSA’s National Survey on Drug Use and Health. Nearly half went without.

Stigma is part of it. In a NAMI and Ipsos poll released in March 2026, almost half of the full-time employees surveyed said they worry they’d be judged for sharing mental health challenges with colleagues. Megan Delp, NAMI’s Director of Workplace Mental Health, said in that release that “real barriers persist in the form of stigma and fear of retaliation or lost opportunities.”

Then look at what the search is actually like. In a secret shopper study published in The American Journal of Managed Care in September 2025, callers trying to book with behavioral health providers listed in marketplace plan directories got appointments with just 14.9 percent of the providers they reached, and the average wait for an offered appointment was 33.2 days.

So people adapt. NAMI’s own guide to finding a mental health professional tells people to get at least three names and numbers, book an appointment even when the wait is long, and then call the second and third numbers on the list. In NAMI’s words: “You can always cancel your first appointment if you find someone who can help you sooner.”

That’s good advice for the person. For your practice, it means the clock starts the moment they reach out. If your callback comes two days later, you may be calling someone who already has a time on another practice’s calendar.

We dig into the person’s side of this in Why Don’t Prospective Patients Call a Practice Back? and the speed side in Why Do Behavioral Health Leads Go Cold Faster Than Other Industries?

“In behavioral health, the person who reached out found the courage once. A callback two days later asks them to find it again.”

What did I learn from being on the other side of the phone?

Once someone is ready to call, the choice of who to call happens fast. When you need help right now, you go down a list, and the list stops at whoever answers. The practices that don’t answer never find out they were in the running.

I wrote about this on Substack a few weeks ago, so some of you have heard it. One Sunday night I was in the barn in the dark with one of our horses, calling vets. The first two calls went to voicemail. The third vet picked up. The vet who answered that night is the vet we use now.

I wasn’t comparing anybody. I wasn’t reading reviews or weighing who had the better clinic. I’m sure the first two practices are excellent, and I’m sure they have good reasons for not staffing a Sunday. None of that was in my head. I was dialing, and I stopped when someone answered.

Here’s the part I didn’t write about then, and it’s the part that belongs here. Those first two practices lost a client that night. Every visit since has gone to the vet who answered. They have no idea. There’s no line in their books for it, because as far as they know, it never happened.

That’s what an unreturned lead looks like from inside the business that missed it. Nothing at all.

“A missed call leaves no trace in your business. The only record of it is on somebody else’s calendar.”

Who should own the callback in a behavioral health practice?

A named person owns the callback for every business hour, with a backup, and the owner decides who that is. That person needs protected time for callbacks, a clear response-time standard to work to, and a written follow-up rhythm the practice set with its clinical leadership.

Beacon’s published standard for responding to a new inquiry is five minutes, with three as the ideal. We hold that number because a person who just reached out is still in the moment that made them call, and that moment doesn’t last.

Then decide what happens when the first attempt doesn’t connect. I want to be careful here, because this is where sales habits can go wrong in our field. A person contacting a therapist for the first time is in a very different place than a business buyer. Each practice should set its own written rhythm with its clinical leadership, use only the channels the person agreed to, and be clear that “contacted” means somebody actually reached the person.

Here’s a simple check I’d put on every owner’s calendar. Once a week, pull every new inquiry from the last seven days and ask one question about each one: did a person at this practice actually speak with them? A call that went to voicemail doesn’t count. The gap between those two lists is your unreturned-lead number, and it’s usually bigger than anyone expects the first time.

Any inquiry that suggests someone may be at risk leaves the routine follow-up rhythm immediately and goes straight to the practice’s clinical protocol. A marketing cadence should never decide how quickly that person hears back.

Stephanie’s piece this Thursday gets into the nuts and bolts of follow-up, including a simple way to secret-shop your own front door. It’s worth doing before January, when the volume climbs. If you haven’t read what breaks first when January arrives, the callback is near the top of the list.

“Whoever owns the callback needs a name, a backup, and a job that won’t keep pulling them away from it.”

Why does an unreturned lead matter beyond the money?

There’s a real person attached to every unreturned lead. Somebody decided today was the day, found your practice, and reached out. When nobody calls back, the practice loses an inquiry. The person may lose the momentum they needed to get help at all.

I use the balance sheet framing because it’s the language that gets an owner’s attention, and I’m not above that. But the money is the smaller loss.

The bigger one is the person who tried once, heard nothing, and quietly decided to wait another month. Or another year. I’ve seen this from enough sides now, as an agency owner, as someone who’s sat in on lead-by-lead reviews with frustrated clients, and as somebody dialing vets in a dark barn, to believe the callback is where a lot of the good in this field either happens or doesn’t.

Marketing is human-to-human connection. The conversions follow when you get the connection right. And the connection can’t start if nobody calls back.

So here’s my question: If you pulled last month’s inquiries today, how many would you find that nobody ever actually reached?

Frequently asked questions

How do you calculate what an unreturned lead costs a practice?

Divide monthly marketing spend by monthly inquiries to get the cost per inquiry. Then estimate a new client’s value as expected sessions times average reimbursement, and multiply that by the share of inquiries that usually become clients. An unreturned lead wastes the spend already sunk into it and gives up the expected value it carried.

How fast should a practice return a new inquiry?

Beacon’s published standard is a response within five minutes of a new inquiry, with three minutes as the ideal. People seeking behavioral health care often contact several practices at once, and the first practice to offer a real conversation and an actual appointment time frequently gets the booking.

How many times should a practice try to reach a new lead?

Each practice should set its own written follow-up rhythm with its clinical leadership, using only the channels the person agreed to. Any inquiry that suggests someone may be at risk should skip the routine rhythm and go straight to the practice’s clinical protocol. An inquiry counts as contacted only when a person was reached.

What counts as “contacted” for a new inquiry?

A new inquiry should count as contacted only when someone at the practice actually spoke or exchanged messages with the person. A voicemail or an unanswered text is an attempt. Logging a single voicemail as “contacted” hides unreturned leads from the owner and makes follow-up look finished when it isn’t.
