How to Send Appointment Reminders Automatically

A customer books a visit, then forgets the time or cannot find the address. A short reminder puts those details back in front of them. You can set it up once in your booking tool instead of writing each message by hand.

Key takeaways

Use one current appointment list.

Include the time, location and change link.

Choose a reminder time customers expect.

The short answer

Start with the reminder feature in your booking tool. Choose when it sends, include the date, time and location, and add a way to change the booking. Test cancellations and moved appointments before turning it on for customers.

Check the tool you already use

Open the settings for your booking page or appointment type. Look for reminders, notifications or automations. These names vary between tools.

Calendly, for example, offers meeting reminders through its Automations feature on supported plans. Check the current plan details before assuming email or text reminders are included. Your existing booking tool may already do enough.

If bookings arrive by phone and are written in a notebook, put them into one shared appointment list first. A reminder cannot use a booking that only exists on paper.

Begin with one useful reminder

For a first test, try one reminder the day before the appointment. That is an example starting point, not a rule for every business. A short online call and an on-site visit may need different notice.

Check what happens when someone books after that reminder time has passed. They should still get the booking details. They should not receive a late reminder for an appointment that has already ended.

Use the customer’s agreed time zone for remote meetings and show it in the message. Check that a late-night booking does not produce an unwanted text in the middle of the night.

Put the useful details in the message

Keep the reminder short enough to read on a phone. Include your business name, the appointment date and time, the address or call link, and a way to change the booking.

Sample: “Hi [name], your appointment with [business] is tomorrow, [date], at [time and time zone]. Join us here: [address or call link]. Need another time? Use [change link] or reply to this message.”

If replies are not monitored, give a contact method that is. Include one preparation note only when the customer needs it, such as bringing a reference number.

Make changed bookings change the reminder

A reminder should use the latest appointment details. If a customer moves Tuesday’s visit to Friday, the old Tuesday reminder must stop. If they cancel, the visit reminder must stop too.

Test this yourself with a spare email address. Book an appointment, move it, then cancel it. Check the messages you actually receive rather than relying only on a settings screen.

Keep reminders in one system where possible. Two tools sending the same reminder can make the booking look uncertain.

Example: a repair appointment

Imagine a repair business with a visit booked for Thursday at 10 am. The reminder sends Wednesday morning with the address and booking reference. The customer replies that they need Friday instead.

A team member moves the appointment in the booking system. Thursday’s reminder is cancelled, and the next reminder uses Friday’s details. The reply stays with the booking so the person making the visit can see the change.

If the message fails to send, the team gets a note to check the contact details. The system should not record “customer reminded” just because it tried to send.

Choose the channel your customer expects

Email is a useful first option if you already collect email addresses for bookings. Add text or WhatsApp reminders only through a supported business setup, using the customer’s contact preferences.

Keep appointment reminders about the appointment. A booking reminder is not a reason to add someone to a separate marketing list. Check message charges and any plan limits before enabling extra channels.

Check whether the setup helps

During the first week, review failed messages, replies and reminders sent with old details. Fix those before adding more messages.

You can also track missed appointments over comparable periods. Keep the number of bookings alongside that count. A quieter week alone does not show that the reminder worked.
