The reminder that actually gets people through the door
Two texts and an email are not a strategy. What we learned from forty million reminders about timing, wording, and the one message that fills a cancelled slot.
Mara Lindqvist
Head of Customer Operations, Thrive
Every practice sends reminders. Most send too many, at the wrong moment, in a voice that reads like a parking notice. Across the reminders that run through Thrive, a handful of patterns separate the messages that work from the ones that get muted.
Timing beats frequency
A reminder sent seven days out is a calendar entry. A reminder sent an hour before is an interruption. The message that changes behaviour lands the evening before, between six and eight, when people are planning tomorrow and can still act on it. One well-timed message outperforms three scattered ones, and it leaves room for the one that matters most.
Ask a question, not a favour
"Please confirm your appointment" gets ignored because it asks the patient to do something for you. "Still good for 9:30 tomorrow with Dr. Nair? Reply Y or N" gets answered because it is a question with a two-character answer. The reply rate roughly doubles, and the N replies are the whole point.
The message that fills the slot
A cancellation is only a problem if the slot stays empty. The practices with the lowest no-show rates are not the ones with the sternest reminders. They are the ones where a cancelled 9:30 triggers a message to the waitlist within a minute:
A slot has opened tomorrow at 9:30 with Dr. Nair. Want it? Reply Y and it is yours.The waitlist recipe, as shipped in Thrive
First to reply gets the slot; everyone else gets a polite "taken, we will keep you on the list". The practice does nothing. That is the entire mechanism, and it fills roughly two in five cancelled slots the same day.
Three rules to steal
- One reminder, the evening before, with a yes-or-no question.
- Every N answer triggers the waitlist before a human sees it.
- Write like a person. Use the clinician's name, use the patient's first name, and never write "failure to attend".
You can build all three as automations in Thrive in under ten minutes. Or you can run them by hand for a week and watch the empty slots disappear anyway — the software just keeps it going when the week gets loud.
