Original research
How fast a med spa replies to a new lead is the strongest single predictor of whether that lead books. Across 186,400 leads from the med spas our team works with, leads answered within one minute booked at 41%. Leads answered after four hours booked at 9%.
Key findings
Each lead was grouped by the time between when it came in and the clinic's first two-way contact attempt (a call, an SMS or an AI conversation). The table shows the share of leads in each group that went on to book a consult or treatment.
At lead level, the Spearman correlation between log response time and booking was −0.58. In a logistic regression controlling for treatment, lead source, clinic and month, every doubling of response time cut the odds of booking by about 11% (odds ratio 0.89, 95% CI 0.88 to 0.90). Speed also affected attendance: leads who booked within five minutes showed up 84% of the time, compared with 71% for those who booked after 24 hours.
Speed gets you in the door. Persistence keeps the lead from going cold.
The sweet spot was four to six attempts across 48 hours. Going beyond seven added little and pushed opt-outs up. Multi-location groups replied more slowly (71 seconds median, versus 41 seconds for single sites), mostly because leads were routed to the wrong location first.
Response time doesn't act alone. When our team built the full follow-up system (instant replies, nurture, reminders and no-show recovery), the median clinic changed like this between its first 90 days and months 4 to 6:
Per 1,000 leads, that's 70 paying patients before and 198 after, 2.8 times as many from the same lead volume. Because cost per patient equals cost per lead divided by (booked rate × show rate × close rate), a 10% gain at any one stage cuts cost per patient by roughly 9 to 10%. The difference is that improving booked and show rates takes automation, while lowering cost per lead takes ongoing ad spend and creative.
Send an automatic SMS within seconds that asks a simple qualifying question, ring the front desk at the same time, and let an AI receptionist take over if nobody picks up within two minutes. Before automation, 23% of leads at the clinics we studied were never contacted at all.
Mix SMS and calls, stop the sequence automatically when the lead books, and move anyone still undecided into a 14-day nurture sequence.
22% of appointments booked by AI in our data happened between 7 pm and 8 am, when most front desks are closed.
Clinics that increased ad spend before fixing follow-up saw cost per new patient rise 18% as the front desk saturated.

The dataset covers 186,400 leads from January 2024 to June 2026, drawn from med spas in the United States and Canada that our team works with and that had full CRM tracking. A lead is a unique person who submitted a form, instant form, call or DM with a phone number or email. Speed to lead is the time from lead creation to the first two-way contact attempt. Booked rate is the share of leads that booked a consult or treatment. Show rate excludes clinic-cancelled appointments. Close rate counts attendees who paid within 14 days. Before-and-after figures compare each clinic's first 90 days (ads live, systems not yet built) with months 4 to 6. Figures are medians across clinics unless stated; Canadian amounts were converted at 1 CAD = 0.73 USD.

Within one minute if possible. In our data, leads answered in under a minute booked at 41%, and the booked rate fell to 24% after 5 to 30 minutes and 9% after 4 to 24 hours.
Four to six attempts over the first 48 hours worked best, booking 31% of leads compared with 14% for a single attempt. Beyond seven attempts, opt-outs rose to 6%.
Both together. An SMS within 10 seconds plus a call within 2 minutes booked 38% of leads, compared with 27% for SMS alone and 24% for a call alone. An AI conversation that booked directly performed best at 41%.
