When every automatic message sends

Every automatic message has a set moment in the patient's journey. You can see this same summary in the app under Settings > Messaging, in the When emails send table.

Around the appointment

Booking confirmation. As soon as the appointment is confirmed.
48-hour reminder. About 48 hours before the appointment. Off by default: most patients only need one reminder, so switch it on under Settings > Messaging if you want the extra touch.
24-hour reminder. About 24 hours before the appointment.
Aftercare advice. Just after the appointment, when an aftercare form is linked to the treatment.
Post-treatment check-in. About 48 hours after the appointment.

When things change

Cancellation notice. When an appointment is cancelled, with a link to rebook.
No-show follow-up. The day after a missed appointment.
Booking recovery. Shortly after a patient starts booking online but does not finish paying the deposit.
Waitlist slot offer. The moment a suitable slot is freed, to patients on your waitlist.

Bringing patients back

Review request. About 72 hours after the visit, once you have added a Google review link. Marketing opt-in only.
Treatment rebooking recall. When a treatment's rebooking interval is due, using the "Rebook after (days)" set on each treatment. Marketing opt-in only.
Rebook nudge. About 80 to 100 days after a lapsed patient's last visit, when they have nothing else booked. Marketing opt-in only.
Birthday greeting. On the patient's birthday. Marketing opt-in only.

Any of these can be switched off for your clinic, and the two reminders and the review request can be re-timed. See the articles on turning automations off and re-timing reminders.
