An appointment reminder template is a short, reusable message that tells a client what is booked, when, where, and how to change it. The method is simple: write three messages once (a confirmation, a reminder a day or two ahead, and a short day-of nudge), then send them on a schedule instead of from memory. You can do all of it free with Gmail's Schedule send and, on an eligible Google plan, the reminder emails built into Google Calendar booking pages. The free way holds for a handful of bookings a week. Past that, scheduling each message by hand becomes the job.
What every appointment reminder template needs
A reminder has one task: get the client to show up, or to cancel early enough that you can refill the slot. Every line should serve that. Clients skim reminders on a phone, often in a notification preview, so the first sentence has to carry the date and time. Everything else is support.
- Who and what. Your business name and the service, so the message is recognized in a second.
- When. Day, date, time, and the time zone if clients book from elsewhere.
- Where. The street address, or the video link, or a note that you will call.
- What to bring or do. Forms, parking, arrive ten minutes early.
- How to change it. A reply option or a reschedule link, plus your cancellation window.
Keep the cancellation rule to one sentence. A reminder that reads like a contract gets ignored. If someone else will see the client, name them in the reminder. Clients forgive a late cancellation more often than they forgive a surprise.
Most clients read the reminder in a phone notification preview. If the first line carries the day and time, the message works even unopened.
Email appointment reminders: three templates to copy
Email carries the detail: directions, preparation notes, the policy. Send the confirmation right after booking, the reminder 24 to 48 hours ahead, and a day-of note only for long or high-value sessions. Replace the bracketed parts and keep the subject lines; they are written to be read in an inbox list.
1. Booking confirmation
Subject: Confirmed: [Service] on [Day, Month Date] at [Time]
Hi [First name],
You're booked for [Service] with [Your name] on [Day, Month Date] at [Time] ([Time zone]).
Where: [Address, or video link, or We'll call you at this number]. Before you come: [One preparation note].
Need to change it? Reply to this email or use [Reschedule link]. Changes made at least [24 hours] ahead are free; later cancellations [your policy in one line].
See you then, [Your name], [Business name], [Phone]
2. Reminder, one or two days before
Subject: Reminder: see you [tomorrow / on Day] at [Time]
Hi [First name], a quick reminder of your [Service] on [Day, Month Date] at [Time].
[Address or link]. [Parking or arrival note.]
If something came up, reply or use [Reschedule link] today so we can offer the time to someone else.
[Your name], [Business name]
3. Day-of note
Subject: Today at [Time]: your [Service]
Hi [First name], we're ready for you today at [Time]. [Address or link]. Running late? Call [Phone].
The second template does the heavy lifting. Today, so we can offer the time to someone else gives a real reason to reply now, which works better than a vague please let us know.
Text message appointment reminders and the consent rule
Texts get read fast, so they should be short: one or two sentences, the time first. Before you text a client at all, settle consent. CTIA, the US wireless industry association, classes appointment reminders as informational messages: the client gives you their mobile number and agrees to receive texts for that specific purpose [1]. Add a line to your booking form or intake sheet that says what the texts are for.
The same guidance covers stopping. Each message should say how to opt out, using the standard word STOP. Plain-language requests such as stop, cancel, end or quit should also be honored. After an opt-out, the sender confirms once and sends nothing more. This is carrier guidance, not legal advice; it is the bar your texts are judged against.
Text template 1, the day before
[Business name]: Hi [First name], reminder of your [Service] tomorrow, [Day] at [Time]. Reply C to confirm or R to reschedule. Reply STOP to opt out.
Text template 2, two hours before
[Business name]: See you at [Time] today, [First name]. [Short address or link]. Reply STOP to opt out.
Put the business name first. A text from an unknown number that starts with Hi reads like spam.
Industry guidance expects the client to agree to reminder texts when they give you their number, and every text to say how to opt out with STOP.
Schedule email appointment reminders free with Gmail
Gmail can hold a message and send it later, which turns your template into a reminder without any extra tool. The steps on a computer, from Google's own help page [2]:
- Open Gmail and click Compose.
- Paste your template and fill in the client's details.
- At the bottom left, next to Send, click the Down arrow.
- Click Schedule send and pick the date and time.
The message then waits in the Scheduled folder. To change it, open it there, click Cancel send, edit, and schedule it again. Google notes three limits: a scheduled email may go out a few minutes late, it follows the time zone you scheduled it in, and you can hold up to 100 scheduled emails.
A mini example. A massage therapist books Tuesday 3 p.m. on Monday morning. She sends template 1 at once, then schedules template 2 for Monday at 3 p.m. Total effort is about two minutes. If the client moves to Thursday, both the calendar entry and the scheduled email need changing by hand.
Google Calendar appointment reminders on a booking page
If clients book through a Google Calendar appointment schedule, Google can send the reminders for you. You need a personal Google Account or a Workspace account, and a computer; appointment schedules cannot be created in the Calendar app for Android, iPhone or iPad [3]. In the schedule's settings:
- Open the section Booking confirmations and reminders.
- Turn on the confirmation email and set the first reminder.
- Click Add reminder for each extra one, up to five.
Two limits shape this. You cannot edit the text of the reminder emails, so your own wording stays in Gmail. And sending automatic email reminders is a premium feature: Google lists it for Google One Premium, Google AI Pro and Ultra, Workspace Individual, Business Standard and Plus, and Enterprise, Education and Nonprofit plans [4]. A free personal account or Business Starter gets a single booking page.
Google's booking-page reminders cannot be edited, so send your own template from Gmail for anything that needs preparation notes or a policy line.
Where the do-it-yourself reminder stops working
The free method breaks at three points, and most small businesses hit the first one. Volume: every booking means one or two scheduled emails (the confirmation goes out at once), and every reschedule means finding and redoing them. At about 20 appointments a week with a reminder and a day-of note each, that is 40 scheduled emails a week, so the 100-email queue holds only about two and a half weeks of bookings ahead, and the editing never ends.
Texts: Gmail and Google's booking page send email. Texting by hand from your own phone means typing each one and tracking every STOP yourself. Wording: Google's automatic reminders use Google's text, not your template.
For the wider plan behind reminders (deposits, policies, refilling slots), see how to reduce no-shows. When the manual queue becomes a chore, a scheduler sends the same templates from its own triggers. Calendly's reminder and follow-up workflows send email and text reminders with your wording from the Standard plan. Setmore emails one reminder per appointment on its Free plan; its setup guide covers the extra email and texts on Pro. TidyCal reminds bookers 1 day and 1 hour ahead on every plan, as its booking and reminder walkthrough shows.
Setmore emails a reminder for every appointment on its Free plan, timed anywhere from minutes to months ahead. Pro adds a second email reminder and a text reminder per appointment.
Every TidyCal plan emails the booker 1 day and 1 hour before. Paid plans let you pick up to two reminder times and write your own email template; Agency Lifetime and Pro add text reminders.
Calendly Workflows send email and text reminders before each meeting and a follow-up after, in your own wording. Marking an invitee a no-show skips the post-meeting messages.

Frequently asked questions
How far in advance should an appointment reminder go out?+
A common rhythm is a confirmation at booking, a reminder 24 to 48 hours before, and a short text two hours before. The day-before reminder matters most, because it still leaves time to refill the slot.
Should an appointment reminder include the cancellation policy?+
Yes, in one sentence: the notice you need and what happens after that. Put the full policy in the confirmation and only the cutoff in later reminders.
Can I send text message appointment reminders from my personal phone?+
You can, but each one is typed by hand and you must track every opt-out yourself. Past a few clients a week, a scheduler that sends the texts from its own triggers saves the typing; keep honoring every STOP reply.
Are email or text appointment reminders better?+
Use both for different jobs. Email carries the detail, such as directions and preparation, while a short text close to the time gets read fastest.
The bottom line
Write three emails and two texts once, using the templates above, and you have most of what reminder software sends. Gmail's Schedule send delivers them free, and an eligible Google plan can add automatic reminders to a booking page with Google's own wording. Get consent before you text and honor STOP every time. When reschedules start eating your week, or you need texts without typing them, move the same wording into a scheduler and let its triggers do the sending.
