Someone books a discovery call. You block the time, read up on them and open Zoom. Ten minutes later, you're still alone.
It's easy to take that personally. But a missed call is often about a busy week, a vague invite or a reschedule that felt awkward. It's not always about interest.
The fix isn't chasing. It's a small, calm system that runs before and after every call. Here is how to set one up, with messages you can copy.
Why booked calls get missed
Most research on no-shows comes from doctor and hospital visits, not sales calls. Still, the patterns are useful.
- They forget. A Cochrane review names forgetfulness as one of the main reasons patients miss appointments.
- The wait is too long. In a 2018 review of 105 studies, Dantas and colleagues found the most often reported predictors of no-shows were a long gap between booking and the visit, and a history of past no-shows.
- They're unsure what the call is. If someone doesn't know how long it takes or whether it's a hard sell, skipping it is easy.
- Moving it feels awkward. If changing the time means writing an apology, some people just don't show up.
The last two are common sense, not study findings. But they're easy to fix.
What the research says about reminders
The best evidence on reminders comes from healthcare. A 2013 Cochrane review by Gurol-Urganci and colleagues pooled eight randomized trials with 6,615 people. Attendance was 67.8% with no reminder, 78.6% with text reminders and 80.3% with phone call reminders. The authors rated the evidence low to moderate quality.
A 2016 review in BMJ Open by Robotham and colleagues pooled 21 randomized studies of text-based reminders. People who got reminders missed 15% of appointments. People who got none missed 21%. Sending more than one reminder raised attendance more than sending just one.
Keep one thing in mind. These are patients going to clinics, not prospects joining sales calls. A prospect may feel less is at stake, so your numbers could look different. Use the research as a guide to what tends to help, not as a promise.
A calm system to cut no-shows
Each step below handles one reason people miss calls. None of it involves chasing. It works the same whether you run a coaching practice or a consulting firm.
1. Make booking quick, and keep the wait short
Ask only what you need on the booking form. Let people pick their own time from your calendar, so there's no back-and-forth.
Then keep the gap short. Offer times in the next few days, not three weeks out. A long wait gives life more chances to get in the way.
2. Set expectations on the confirmation page and email
Your confirmation page and email should answer four questions:
- What will we cover?
- How long will it take?
- Who will I talk to?
- How do I join, and how do I change the time?
Keep it short and friendly. One line like "This is a conversation, not a pitch" can ease a lot of nerves.
There's some support for this. A 2016 review by McLean and colleagues found that reminders with extra useful details, beyond the date and time, may work better than simple ones in some cases. The authors noted this may help most with first appointments. A discovery call is a first appointment too.
3. Send a real calendar invite
If your call isn't on their calendar, it's easy to forget. Send an invite with the join link and your reschedule link inside it.
Concrete plans seem to help people follow through. In a 2011 study at a large US company, Milkman and colleagues mailed flu shot reminders to employees. Some were asked to write down the date and time they planned to go. That group's vaccination rate was 4.2 percentage points higher than the control group's 33.1%. An invite isn't the same as writing it down, but it puts a clear time where they'll see it.
4. Ask one or two short pre-call questions
A question or two on the booking form does two jobs. It helps you prepare. And it asks the person to put a little thought into the call, so it feels more like their plan.
- What's the main thing you'd like help with right now?
- What would make this call a good use of your time?
Stop at two. A long form adds friction, and friction is what you're trying to remove.
There's a small hint from healthcare here. In a 2012 paper, Martin and colleagues described a project at two UK family practices. When nurses booked follow-ups, patients wrote the date and time on the card themselves. Missed appointments then fell 18% compared with the previous six-month average. It wasn't a randomized trial, so treat it as a clue, not proof.
5. Send two short reminders
One reminder helps. Two tend to help more, based on the BMJ Open review above. A simple rhythm:
- The day before: the time, the join link and the reschedule link. This gives them room to move the call if they need to.
- About an hour before: a one-line nudge with the join link.
McLean's team suggested clinics send reminders at least two to three days ahead, so people have time to rearrange plans. Discovery calls are often booked just a few days out, so the day before is a practical middle ground. If the call is a week or more away, add a reminder two or three days before as well.
Only text people who agreed to receive texts from you. FCC rules ban autodialed texts to cell phones unless the owner gave consent first.
Day-before reminder (email or text)
Hi Sam, a quick reminder about our call tomorrow, Tuesday at 2:00 pm Eastern. It's 20 minutes on Zoom, just you and me. We'll talk about [their goal] and see if I can help.
Join here: [call link]
If the time no longer works, pick a new one here: [reschedule link]. No need to explain.
One hour before (text)
Hi Sam, talk soon at 2:00 pm ET. Here's the link: [call link]. Need a new time? [reschedule link]
6. Make rescheduling one click
Put a reschedule link in every message: the confirmation, the invite and each reminder. Say plainly that changing the time is fine.
This can feel backwards. Won't it invite people to cancel? McLean's review found reminders can increase cancelling and rescheduling, and the authors saw that as a good outcome. A call moved ahead of time frees your slot. A silent no-show just wastes it.
7. Follow up kindly when someone misses
Some people will still miss. Life happens. Send one short, warm message soon after. Skip the guilt, and don't mention how long you waited.
No-show follow-up (email)
Hi Sam, looks like we missed each other today. No worries, weeks get busy.
If you'd still like to talk about [their goal], you can grab a new time here: [rebooking link].
And if now isn't the right time, just reply "later" and I'll leave it there.
If they don't reply, one more short note a few days later is plenty. Then let it rest. A kind exit makes it easier for them to come back when the timing is right.
What to measure
Start with one number: your show rate. It's the share of booked calls that actually happen. Count a call that was moved ahead of time as a reschedule, not a no-show.
| Metric | How to work it out | What it tells you |
|---|---|---|
| Show rate | Calls held divided by calls booked | Whether the whole system is working |
| Reschedule rate | Calls moved ahead of time divided by calls booked | Whether changing the time feels easy |
| Rebook rate | No-shows who book again divided by all no-shows | Whether your follow-up is landing |
| Days to call | Average days from booking to the call | Whether people wait too long |
Check these once a month. Change one thing at a time, like reminder timing, and watch the next few weeks. With small numbers, look for clear trends, not one good week.
Running it without extra work
None of this needs you to remember anything. A CRM, which is one place for every lead, conversation and next step, can send the confirmation, reminders and no-show follow-up for you. Many booking tools can handle parts of it too.
This is the kind of booking flow Nucleus Growth Systems sets up inside the CRM you already use. To see how it fits with the rest of your follow-up, look at how the full system works.
